Federal Motor Vehicle Safety Standards; Lamps, Reflective 
Devices, and Associated Equipment

AGENCY: National Highway Traffic Safety Administration (NHTSA), 
Department of Transportation.

ACTION: Final Rule.

-----------------------------------------------------------------------

SUMMARY: This document amends the Federal Motor Vehicle Safety Standard 
(FMVSS) No. 108 on lamps, reflective devices, and associated equipment 
by reorganizing the regulatory text so that it provides a more 
straightforward and logical presentation of the applicable regulatory 
requirements, which includes the agency's interpretation of the 
existing requirements. It also greatly reduces the need to consult 
relevant third-party standards by including applicable requirements 
directly into the main body of Standard No. 108, rather than 
incorporating such provisions by reference. This final rule does not 
impose any new substantive requirements on manufacturers.
    In addition, this document amends 49 CFR Part 564, Replaceable 
Light Source Information, by adding a newly created Appendix C, which 
relocates figures addressing sealed beam headlamps that currently 
reside in FMVSS No. 108 and a relevant Society of Automotive Engineers 
(SAE) standard there. We believe few lighting manufacturers still 
produce sealed beam headlamps, and their diminishing use is unlikely to 
draw new manufacturers of this type of lamp. Accordingly, we see no 
drawbacks to consolidating the information regarding sealed beam light 
sources with other light source information currently located in 49 CFR 
Part 564.

DATES: Effective date: The final rule is effective September 1, 2008 
with voluntary early compliance permitted immediately. The 
incorporation by reference of certain publications listed in the rule 
is approved by the Director of the Federal Register as of September 1, 
2008. Petitions for reconsideration: Petitions for reconsideration of 
this final rule must be received not later than January 18, 2008.

ADDRESSES: Any petitions for reconsideration should refer to the docket 
number of this document and be submitted to: Administrator, National 
Highway Traffic Safety Administration, 1200 New Jersey Avenue, SE., 
West Building, Ground Floor, Docket Room W12-140, Washington, DC 20590.

I. Executive Summary

    After carefully considering the public comments on its December 
2005 proposal, the agency has decided to adopt a final rule amending 
Federal Motor Vehicle Safety Standard (FMVSS) No. 108, Lamps, 
Reflective Devices, and Associated Equipment, by reorganizing the 
regulatory text and directly importing requirements from applicable SAE 
standards currently incorporated by reference into the regulatory text. 
In doing so, the agency has decided to make some changes from the NPRM, 
including modifying the organizational structure of the standard, 
relocating test procedures and performance requirements from attached 
tables to the regulatory text, and incorporating the substance of 
several additional interpretations into the standard. In addition, 
three SAE documents that the agency had proposed to continue to be 
incorporated by reference in the NPRM have now been integrated into the 
regulatory text, and the location of marking requirements within the 
standard has been further consolidated.
    Consistent with the NPRM, the final rule also establishes an 
Appendix C in 49 CFR Part 564, Replaceable Light Source Information, as 
a repository for dimensional and electrical information associated with 
standardized sealed beam headlamps that currently resides in figures in 
FMVSS No. 108.
    These modifications have furthered the objective of this rewrite by 
increasing clarity as follows: (1) Making requirements easier to find 
and comprehend; (2) presenting performance requirements and test 
procedures together through the inclusion of relevant provisions of 
third-party documents (previously incorporated by reference) directly 
into the regulatory text of the standard; and (3) updating Standard No. 
108 to reflect significant letters of interpretation. The rewrite of 
FMVSS No. 108 is considered administrative in nature because the 
standard's existing requirements and obligations are not being 
increased, decreased, or substantively modified. Accordingly, costs 
associated with manufacturer compliance with Standard No. 108 are not 
expected to change as a result of this regulatory action.

II. Background

A. Historical Overview of the Standard

    On December 30, 2005, NHTSA published a notice of proposed 
rulemaking \1\ (NPRM) to amend FMVSS No. 108, Lamps, Reflective 
Devices, and Associated Equipment, by reorganizing the regulatory text 
so that it provides a more straight-forward and logical presentation of 
the applicable regulatory requirements. The initial version of FMVSS 
No. 108 was adopted almost 40 years ago to increase motor vehicle 
safety by establishing minimum requirements for vehicle lighting, 
reflective devices, and associated equipment. In developing the 
standard, NHTSA incorporated requirements from a number of industry 
consensus standards, in particular SAE standards. At that time, motor 
vehicle technologies were relatively simple, as compared to today's 
designs. For example, motor vehicle headlighting systems were limited 
to ones consisting of either two

[[Page 68235]]

7-inch or four 5\3/4\-inch round sealed beam units. During the ensuing 
years, a number of rectangular sealed beam units, replaceable bulb 
headlamps, and integral beam headlamps were developed, and FMVSS No. 
108 was amended to permit the use of these new technologies. Later, the 
standard was further amended to add requirements for high-mounted stop 
lamps, side marker lamps, and side reflex reflectors, to allow for 
daytime running lamps, and to address the conspicuity needs of large 
vehicles.
---------------------------------------------------------------------------

    \1\ 70 Fr 77454, (Dec. 30, 2005) (Docket No. NHTSA-2006-23634-
3).
---------------------------------------------------------------------------

    However, such amendments were made on an ad hoc basis, which, over 
time, resulted in a patchwork organization for FMVSS No. 108. 
Furthermore, when regulated parties had questions regarding how FMVSS 
No. 108 should be interpreted (in many instances due to rapid advances 
in lighting technology not fully anticipated or addressed by the 
existing regulatory text), they submitted requests for interpretation 
to the agency on specific issues. Since its promulgation, a large 
number of interpretation letters have been issued pertaining to 
Standard No. 108. Thus, in its current state, FMVSS No. 108 has 
requirements that are located directly in its regulatory text, located 
in referenced and sub-referenced SAE standards, and elaborated upon in 
various agency interpretations. Since its inception, NHTSA has never 
completed a thorough reorganization of the entire standard.

B. The Need for an Administrative Rewrite of the Standard

    Due to concerns about being able to locate requirements efficiently 
and the apparent lack of clarity associated with the standard (as 
demonstrated by an abundance of letters of interpretation), we decided 
to undertake an administrative rewrite of FMVSS No. 108. The agency has 
also received complaints that the current text of FMVSS No. 108 
sometimes results in confusion, in part due to the way it is organized. 
Regulated parties have stated that the current organization of FMVSS 
No. 108 makes it difficult for them, at times, to be fully confident 
that all applicable requirements have been identified and satisfied 
prior to certification to the standard. Also, numerous interested 
parties have stated that the large number of interpretations that have 
been issued by the agency regarding Standard No. 108 make it difficult 
to locate and identify the agency's position on relevant issues. In 
addition, regulated parties have conveyed to the agency in recent years 
that some of the older versions of SAE standards incorporated by 
reference into FMVSS No. 108 are no longer readily available from SAE 
International.
    Throughout the past few decades, SAE has published revised, 
successor versions, with differing requirements, for many of their 
standards incorporated by reference into FMVSS No. 108. This appears to 
sometimes cause confusion on the part of regulated parties who, 
mistakenly, may believe that the most recent version of a SAE standard 
represents the regulatory requirement. The agency believes that 
interested parties should have easy access to the requirements of the 
standard, and, therefore, we believe there is value in publishing, 
without substantive change, applicable requirements that are currently 
contained in third-party documents directly within FMVSS No. 108 
itself. The same logic applies to our decision to include the results 
of relevant legal interpretations in the standard. Furthermore, several 
provisions currently in Standard No. 108 refer to regulatory inception 
dates that are several years in the past, so the agency is eliminating 
text citing such past dates.
    For these reasons, we believe that the benefits of an 
administrative rewrite of FMVSS No. 108 (e.g., making the standard more 
navigable and thereby facilitating compliance with existing 
requirements) justify the necessary commitment of agency resources to 
accomplish this reorganization of the standard.

III. December 2005 Notice of Proposed Rulemaking (NPRM) and Public 
Comments

A. The NPRM

    As noted above, NHTSA published a NPRM on December 30, 2005 that 
proposed to reorganize FMVSS No. 108 to improve the clarity of the 
standard's requirements, thereby increasing its utility for interested 
parties. This administrative rewrite attempted to make the standard 
more understandable by adopting a simplified numbering scheme, to 
improve organization by grouping related materials in a more logical 
and consistent sequence, and to reduce reliance on references to third-
party documents. As proposed, the reorganized standard progressed from 
vehicle-level requirements to device-level requirements, beginning with 
the most common requirements and then proceeding to exceptions.
    The NPRM also proposed to move figures addressing sealed beam 
headlamps that are currently included in FMVSS No. 108 and SAE J1383 
APR85, Performance Requirements for Motor Vehicle Headlamps, into 49 
CFR Part 564, Replaceable Light Source Information, as a newly created 
Appendix C. This modification would be consistent with the current 
practice of placing replaceable light source information in Part 564. 
The title of Part 564 would also be changed to ``Replaceable Light 
Source and Sealed Beam Headlamp Information'' to reflect the addition 
of the sealed beam headlamp content.
    Whereas Standard No. 108 currently references approximately 35 
different SAE documents in nearly 100 separate instances, the NPRM 
proposed reducing that number to eight documents, which were ones 
believed not to be routinely used by regulated parties. Accordingly, 
the NPRM proposed to incorporate the content of these frequently used 
SAE documents directly into the regulatory text and/or attached tables 
of Standard No. 108.
    The proposed tables included Table I, which listed the required 
lamps and reflective devices for the various vehicles regulated by 
FMVSS No. 108. The number of required lamps and reflective devices, 
their color, their mounting locations and height above the road 
surface, and their manner of activation were included in Table I, which 
resembles an expanded version of Tables I through IV of the current 
FMVSS No. 108. Table II detailed the requirements for the four 
different kinds of headlighting systems permitted by the standard. 
Table III contained the conspicuity system requirements for large 
trucks and trailers, while Tables IV and V provided, respectively, 
effective projected luminous lens area requirements and visibility 
requirements. Tables VI through XII and XIV through XX listed 
photometric requirements for individual lamp types. Table XIII detailed 
the target locations for license plate lamp photometry. Table XXI 
contained test procedures and performance requirements for all 
associated devices. Finally Tables XXII and XXIII contained non-
photometry test procedures and performance requirements for all lamps, 
reflective devices, replaceable light sources, and vehicle headlamp 
aiming devices (VHAD). In addition, several new figures were included 
to clarify some of the application requirements for conspicuity 
systems.
    From a regulatory perspective, it was the agency's intention, as 
expressed in the NPRM, that the administrative rewrite of Standard No. 
108 would neither result in any current obligation being diminished, 
nor any new obligation being imposed. In other words, the substantive 
requirements are identical to those of the current version

[[Page 68236]]

of FMVSS No. 108, including incorporated documents. Therefore, we do 
not believe that vehicle manufacturers and lighting manufacturers would 
have to make any changes to their respective products or production 
processes if the NPRM were made final.

B. Public Comments Received in Response to the NPRM

    The agency received comments from twenty seven entities in response 
to the December 2005 NPRM, which were submitted by 11 lamp or lamp 
component manufacturers, 11 manufacturer or user associations, three 
vehicle manufacturers, and two test organizations. Commenters included: 
Truck Manufacturers Association (TMA), Motorcycle Industry Council 
(MIC), Koito Manufacturing Co., Ltd., (Koito), Truck Trailer 
Manufacturers Association (TTMA), General Electric Automotive Plastics 
(GE-Plastics), General Motors North America (GM), Specialty Equipment 
Market Association (SEMA), Grote Industries, L.L.C., (Grote), 
Innovative Lighting, Inc., Calcoast Industrial Testing Laboratory 
(Calcoast), General Electric Automotive Lighting (GE), Valeo Sylvania, 
L.L.C. (VS), Guide Corporation (Guide), Alliance of Automobile 
Manufacturers (AAM), 3M Traffic Safety Systems (3M), Valeo Lighting 
Systems (Valeo), Association of International Automobile Manufacturers 
(AIAM), Owner-Operator Independent Drivers Association, Inc. (OOIDA), 
Atlas Material Testing Solutions (Atlas), American Trucking 
Associations, Inc. (ATA), Honda Motor Co., LTD. (Honda), Nissan North 
America, Inc., (Nissan), and Bayer Material Science, L.L.C., (Bayer). A 
joint response was submitted by Motor and Equipment Manufacturers 
Association (MEMA), Transportation Safety Equipment Institute (TSEI), 
and Motor Vehicle Lighting Council (MVLC), collectively the 
Associations (ASSN). Several months after the comment closing date the 
Associations submitted a supplementary response which was shortly 
followed by another supplementary response in conjunction with the 
Alliance (AAM/ASSN). All comments are available in Docket No. NHTSA-
2006-23634 and were considered in the promulgation of this final rule.
    The comments about the NPRM that we received can be divided into 
five general categories: (1) Administrative Considerations; (2) 
Omissions, Typographical Errors, and Inconsistent Language; (3) 
Organizational Structure; (4) Suggestions Beyond the Scope of the 
Rewrite; and (5) Suggestions Within the Scope of the Rewrite. A summary 
and analysis of each issue identified is provided below.

(a) 49 CFR Part 564

    We received only one substantive comment concerning the relocation 
of the sealed beam headlamp figures into a new Appendix C of Part 564 
of this chapter. GE requested a separate NPRM for this purpose and that 
the drawings that would be filed in Appendix C be made available for 
review.
    We stated in Summary of the Proposal in the NPRM that the final 
rule adopting the rewrite of Standard No. 108 would occur concurrently 
with the relocation of the sealed beam figures to Appendix C of Part 
564. We also provided, at the end of that notice, a complete listing of 
all the figures and where they currently reside in FMVSS No. 108 or SAE 
J1383 APR85, which is incorporated by reference in the current version 
of FMVSS No. 108, but we did not provide specific regulatory text for 
Appendix C in the NPRM. Ample opportunity was provided for public 
comment on this issue, so we are making the establishment of Appendix C 
of Part 564 of this chapter and the transfer of the identified figures 
to it part of the final rule. We believe that it would be beneficial 
for the sealed beam drawings to be relocated as part of this 
reorganization so that applicable requirements are transferred in an 
accurate manner, thereby satisfying our commitment not to change the 
existing requirements of the standard.

(b) 49 CFR 571.108
1. Administrative Considerations
    Some of the comments submitted in response to the NPRM were not 
focused upon the substance of the rewrite but rather addressed 
administrative concerns. Several commenters requested statements of 
reassurance that ``* * * no substantive changes from existing 
requirements are intended,'' and ``* * * state that the existing body 
of interpretations is still valid.'' On these points, we clarify as 
follows. First we reiterate that the administrative rewrite, as 
expressed in this final rule, does not make any substantive changes to 
the requirements of Standard No. 108. Furthermore, as stated in the 
NPRM, not all letters of interpretation were appropriate for inclusion 
into the regulatory language of FMVSS No. 108. Generally, we excluded 
those that we concluded did not add value to the regulatory text (i.e., 
one without broad applicability). However, all existing letters of 
interpretation, whether or not they are specifically integrated into 
the FMVSS No. 108 final rule, continue to reflect the legal opinion of 
the agency unless they contradict the explicit regulatory text of the 
standard or were overturned by subsequent interpretations.
    AAM suggested that the final rule should not be mandatory until 
September 1st, one year after publication of the final rule. We have 
established September 1, 2008 as the mandatory compliance date, with 
voluntary early compliance permitted immediately.
    ATA, OOIDA, and TMA all expressed concern about conflicts between 
FMVSS No. 108 and the regulations of the Federal Motor Carrier Safety 
Administration (FMCSA). They requested that the rewrite of Standard No. 
108 reconcile the differences that they perceive between it and the 
regulations of the FMCSA.
    The FMCSA has established regulations for lamps, reflective 
devices, and associated equipment for commercial vehicles in use and a 
few specialized types of commercial vehicles at time of manufacture. 
The FMCSA made significant revisions to its lighting regulations in 
2005 \2\ and some substantive differences do exist between the lighting 
regulations of FMCSA and FMVSS No. 108. These differences may have the 
potential to cause manufacturers of lamps and reflective devices that 
fall under the jurisdiction of both NHTSA and FMCSA to pursue different 
design, manufacturing, and compliance processes to satisfy the 
regulations of both agencies. However, any attempt at reconciliation 
here would be outside the scope of the rewrite process. Recently, FMCSA 
issued a final rule \3\ in response to a petition for reconsideration 
to its August 15, 2005 final rule, which resolved the differences 
between its regulations and FMVSS No. 108, as interpreted in NHTSA's 
July 28, 2005 interpretation to Mr. Clarke,\4\ concerning auxiliary 
lamps mounted near identification lamps. Regulated parties may want to 
consider other approaches to address the remaining differences between 
FMVSS No. 108 and 49 CFR Part 393. One such approach could be to submit 
rulemaking petitions to NHTSA and FMSCA requesting reconciliation of 
the differences between FMVSS No. 108 and 49 CFR Part 393.

2. Omissions, Typographical Errors, and Inconsistent Language
    Given the complexity of the proposed administrative rewrite of 
FMVSS No. 108, including the integration of the content of numerous SAE 
standards incorporated by reference into the regulatory text, some 
omissions and typographical errors occurred. Numerous comments were 
received identifying such occurrences. Accordingly, we have amended the 
regulatory text of the final rule to correct these errors.
    Some respondents have noted instances where they believe that the 
language of the regulatory text used in the NPRM was not faithful to 
the language and intent of the current FMVSS No. 108. In many instances 
where a claim of unfaithful language was made in the comments, the 
agency adopted a conservative approach, choosing to revise the language 
of the NPRM back to that of the original document in the final rule. 
Where such a revision was not made, we have stated our reasons for that 
decision.
    Two rather significant instances where contradictory regulatory 
language was found to exist in the current version of FMVSS No. 108 and 
its incorporated documents are discussed here. One has to do with the 
appropriate photometric requirement for a specific type of replaceable 
bulb headlamp and is discussed in detail in the section devoted to 
Table II. The other concerns the ratio between the stop lamp function 
and the taillamp function in a lamp where those functions are optically 
combined. The discussion related to Table IX contains an explanation of 
this issue. Both instances bolster our opinion that regulatory 
requirements should be stated once and only once in a document. Neither 
instance has ever generated an interpretation request nor did many 
respondents raise either issue in their comments to the docket. This 
reinforces our belief that, notwithstanding the existence of ambiguous 
regulatory language, the intent of the specific requirements was clear.
    Because correction of either situation would require a substantive 
change to FMVSS No. 108, we have decided to refrain from addressing 
these examples now. However, we may issue a notice of correction in the 
near future to address what we believe are mistakes and inconsistencies 
that have existed for some time in Standard No. 108.
3. Organization of the Standard
    The organizational structure of the reorganized standard, as 
presented in the NPRM, progressed from vehicle-level requirements to 
device-level requirements, beginning with the most common requirements 
and then proceeding to exceptions. Requirements in the rewrite of FMVSS 
No. 108 are consolidated into dedicated paragraphs. Paragraphs S1 
through S4 were organized in the same manner as the present standard. 
S4, Definitions, was expanded to incorporate relevant definitions from 
the applicable SAE standards previously incorporated as part of 
Standard No. 108. Paragraph S5 addressed the remaining references to 
SAE standards. Vehicle-level requirements were located in paragraph S6, 
including requirements by vehicle type. Following that, requirements 
were organized with dedicated sections for each type of lamp and 
reflective device, beginning with signal lamps, reflective devices and 
associated equipment under paragraph S7, and headlamp and headlighting 
requirements under paragraphs S8 through S13, and S16 through S18. 
Paragraph S14 addressed aimability performance requirements, while 
paragraph S15 contained requirements for replaceable light sources 
(including references to Part 564). In order to make requirements 
easier to find, a Table of Contents was added as an appendix to the 
standard.
    The most detailed comments about the organizational structure of 
the standard were those in the supplementary response from the ASSN/
AAM, which recommended a significantly different organizational 
structure that would divide the content of FMVSS No. 108 into four 
sections. Under the ASSN/AAM structure, the first section would contain 
general and specific lamp requirements, and the second section would 
consist of Tables I, II, III, VI, VII, VIII, IX, X, XI, XII, XIV, XV, 
XVI (split into three separate tables), XVII, XVIII, XIX, and XX. 
However, there would be some format changes to lamp photometry tables 
and the addition of graphical illustrations of photometric test points. 
These commenters similarly suggested three new tables that would 
graphically illustrate the required photometric test points, lines, and 
areas associated with upper beam headlamps, lower beam mechanically 
aimed headlamps, and lower beam visually/optically aimed headlamps. The 
third section would contain all the figures of the NPRM as well as 
Table XIII, License Plate Lamp Target Locations, redesigned as Figure 
19. The fourth section would be subdivided into five annexes which 
would contain photometric test procedures and the physical test 
procedures of Tables XXI, XXII, and XXIII.
    ASSN/AAM also suggested dividing Table I into five separate tables: 
one for vehicles less than 80 in (2032 mm) in overall width, another 
for vehicles 80 in (2032 mm) or more in overall width, one for 
trailers, one for motorcycles, and one for school buses. The activation 
requirements would be removed from these tables and located in a new 
paragraph titled ``Electrical.'' Tables IV and V covering projected 
luminous lens area and visibility would be eliminated and their 
requirements dispersed to the applicable individual lamp sections. 
These individual lamp sections would have a common format divided into 
14 subsections representing specific requirements. An additional table 
would be created that would contain all marking requirements.
    In consideration of the comments submitted by ASSN/AAM, we have 
decided to make significant changes to the structure of the standard 
presented in the NPRM. These structural changes include: (1) Relocating 
test procedures and performance requirements that were primarily 
contained in paragraph S6.8 and Tables XXI, XXII, and XXIII of the 
proposal, to paragraph S14 of the final rule; (2) expanding and 
standardizing the presentation of requirements in individual lamp and 
reflective device sections of the final rule beyond that of the 
proposal; (3) including the provisions from additional SAE documents, 
incorporated by reference in the proposal, in the regulatory text of 
the final rule; and (4) further consolidating the location of marking 
requirements in the final rule beyond that of the proposal.
    We believe there is value in adopting a structure in the final rule 
that is easy for regulated parties to navigate. There were some aspects 
of the ASSN/AAM recommended structure that we did not adopt due to our 
effort to avoid redundancies, streamline the standard, and avoid adding 
new material not currently contained in Standard No. 108, including 
graphs, which could cause confusion. We believe that our approach in 
modifying the structure of the NPRM will collectively provide the most 
value to all end-users.
    We have decided to adopt the ASSN/AAM recommendation regarding 
reorganization of the layout of several photometry requirement tables 
for reasons that follow. Standard No. 108 provides two alternative 
methods for demonstrating the photometric compliance of turn signal 
lamps, taillamps, stop lamps, backup lamps, parking lamps, and high-
mounted stop lamps. For these lamps compliance can

[[Page 68238]]

be demonstrated by achieving a minimum photometric intensity at each of 
18 to 22 discrete test points distributed within a pattern about 
20[deg] high and 40[deg] wide centered about the H-V axis.\5\ 
Alternatively, FMVSS No. 108 also permits these specific lamps to 
demonstrate compliance by meeting a minimum photometric intensity for 
groups of these test points. Individual test points in proximity to 
each other are organized into groups consisting of from two to six 
points. The minimum photometric intensity requirement of each group is 
approximately (but not always exactly) the arithmetic sum of the 
minimum photometric intensities of all included points. This allows a 
lamp where one or more test point(s) in a group do not meet their 
individual minimum values to be compliant provided the remaining test 
points in the group exceed their minimum values by enough to allow the 
group total to exceed the group requirement.\6\ Turn signal lamps, 
taillamps, stop lamps, and parking lamps have five groups of test 
points; while backup lamps have six groups, and high-mounted stop lamps 
have four groups.
---------------------------------------------------------------------------

    \5\ The pattern is wider for backup lamps and tighter for high 
mounted stop lamps.
    \6\ No individual test point photometric intensity can fall 
below 60% of the point requirement when the group photometric method 
is used. In addition, photometric values between adjacent test 
points are regulated.
---------------------------------------------------------------------------

    Tables VI, VII, VIII, IX, XII, XV, which detail photometry 
requirements for those lamps permitted to use both the individual test 
point and the grouped test point compliance methods, are formatted such 
that test points are organized in group order. Progressing from left to 
right horizontally, each test point group is identified by number, and 
then the individual test points included within that group are 
identified by their vertical and horizontal positions. Next, the 
minimum photometric intensity for each individual test point is shown, 
and finally, at the right end, the group minimum photometric intensity 
is shown.
    In contrast, the photometry requirements tables suggested by the 
ASSN/AAM, and endorsed by Calcoast, organize the lamp test points in a 
vertical, then horizontal, manner that requires the user to search for 
each point to include in a group and then consult a sub-table to find 
out the minimum photometric requirement for that group. We find this 
suggested approach unnecessarily complex and prone to increasing, not 
decreasing, the possibility of error in determining photometric 
requirements. Therefore, we have decided to retain the format of the 
photometric tables as presented in the NPRM with one simplification, 
which was to locate the horizontal and vertical test point positions in 
the same relative positions in each table.
    Calcoast suggested, and we agree, that the horizontal test point 
positions and the vertical test point positions should always appear in 
the same columns. In our earlier proposal, this was not the case, and 
we have made modifications consistent with Calcoast's suggestion. The 
final rule designates the horizontal test point positions in a column 
to the left of a column that designates the corresponding vertical test 
point positions.
    Nissan suggested that those lamps that are permitted to demonstrate 
photometric compliance by either the individual test point method or 
the grouped test point method have the required photometric intensity 
values for each individual test point reduced to 60 percent of the 
current requirement and only allow use of the grouped test point 
method. We did not adopt this suggestion because it would have reduced 
the number of compliance methods available to manufacturers, a 
substantive change beyond the scope of this administrative rewrite.
    The original response from the ASSN, as well as the comments from 
Guide, suggested abandoning Tables XVIII and XIX and incorporating 
headlamp photometry requirements in a series of tables similar to the 
current FMVSS No. 108. We were not persuaded that more headlamp 
photometric tables would add value to the standard. Upper beam headlamp 
requirements are not related to whether a headlamp is mechanically or 
visually/optically aimed and six beam patterns adequately cover all 
headlamps. Many photometric test points are common to all lower beam 
headlamps. Tables XVIII and XIX present all required beam patterns 
(except for certain motorcycle headlamps) in a clear and concise 
format. Table II directs the user to the appropriate beam pattern in 
Tables XVIII and XIX. We retained this format for headlamp photometry 
requirements in the final rule.
    Several commenters mentioned inconsistent use of a ``no 
requirement'' indicator where a test point appears in a photometry 
requirements table but there is no value required at that point. Our 
proposal used both a blank space and a N.R. notation. In the final 
rule, we have adopted a consistent indicator that there is no 
requirement for a test point. A dashed line (-) is used exclusively for 
this purpose in photometry requirements tables.
    Commenters generally favored the use of tables in the NPRM for 
presenting performance requirements. However, Nissan, Grote, and TTMA 
all commented that Table I was too lengthy and should be separated into 
several sections based on common content. The Alliance suggested 
splitting Table XXIII into three separate tables because it contains 
tests for three distinctive items: (1) Headlamps, (2) vehicle headlamp 
aiming devices (VHAD), and (3) replaceable light sources. The 
differentiation of content in Table II of the NPRM was mentioned as 
being a particularly appropriate method of providing distinction.
    Several commenters, including ASSN/AAM and Grote, noted that tables 
containing significant amounts of text, such as the test requirements 
in Tables XXI, XXII, and XXIII, would be difficult to use because of 
lengthy passages that contain several sentences and express several 
unique test conditions or requirements. We agree with these comments. 
The tabular format is best suited to displaying quantitative values or 
short textual requirements. In the final rule, we moved virtually all 
test procedures and performance requirements to S14, the last section 
of the standard. Specifically, the content of Table XXI of the NPRM has 
been moved to S14.9, Associated Equipment Physical Test Procedures and 
Performance Requirements, the content of Table XXII of the NPRM has 
been moved to S14.3, Motorcycle Headlamp Out of Focus Test Procedures 
and Performance Requirements, S14.4, General Test Procedures and 
Performance Requirements (consisting of the color test and plastic 
optical materials test), and S14.5, Signal Lamp and Reflective Device 
Test Procedures and Performance Requirements. In addition, the content 
of Table XXIII of the NPRM has been moved to S14.6, Headlamp Physical 
Test Procedures and Performance Requirements, S14.7, Replaceable Light 
Source Physical Test Procedures and Performance Requirements, and 
S14.8, Vehicle Headlamp Aiming Devices (VHAD) Physical Test Procedures 
and Performance Requirements.
    General test procedures and performance requirements that were 
located in S6.8 of the NPRM have been placed in S14.1 of the final 
rule. Similarly, the photometric test procedures of S6.8 of the NPRM 
are now in S14.2 of the final rule.
    In the final rule, we decided to split several of the tables into 
shorter, more distinctive, sections and we completely revised the 
content of Table III and Table XIII. Table I, Required Lamps and

[[Page 68239]]

Reflective Devices, is divided into three parts: (1) Table I-a for 
passenger cars, multipurpose passenger vehicles, trucks, and buses of 
all widths; (2) Table I-b for trailers, and (3) Table I-c for 
motorcycles. We decided upon sectioning Table I in this manner for 
several reasons. One is user diversity. Organizations that manufacture 
vehicles such as passenger cars, multipurpose passenger vehicles, 
trucks, and buses typically do not also manufacture trailers or 
motorcycles. Likewise, organizations that manufacture trailers 
typically do not manufacture self propelled vehicles, and those that 
manufacture motorcycles do not produce cars, trucks, or trailers. Some 
commenters suggested separate sections for narrow vehicles (less than 
2032 mm in width) and wide vehicles (those 2032 mm or wider). However, 
several manufacturers produce both narrow and wide vehicles, sometimes 
as different optional versions of the same vehicle, such as pickup 
trucks.
    Another consideration was commonality. Both narrow and wide 
vehicles are required to be equipped with a headlighting system, turn 
signal lamps, taillamps, stop lamps, side marker lamps, side and rear 
reflex reflectors, backup lamps and license plate lamps. Narrow 
vehicles are required to have parking lamps and high-mounted stop lamps 
while wide vehicles are not. Similarly, wide vehicles must have 
clearance and identification lamps which are not required on narrow 
vehicles. This same distinction occurs between narrow and wide 
trailers, for which common content significantly surpasses 
differentiated content. Therefore, we have concluded that it is 
unnecessary to section Table I by vehicle width.
    We are retaining the title of the three sections of Table I as 
Required Lamps and Reflective Devices, even though one of the lamps 
listed in Table I-a, Daytime Running Lamp (DRL), is not a required 
lamp. The heading above the DRL listing clearly describes it as being 
permitted but not required. However, because the DRL, when installed, 
is regulated in all attributes listed in Table I, Number and Color, 
Mounting Location, Mounting Height, and Device Activation (unlike other 
non-required lamps), the agency decided that Table I is the appropriate 
location for it.
    The three sections of Table IV, Effective Projected Luminous Lens 
Area Requirements, are now identified as: (1) Table IV-a covering turn 
signal and stop lamps; (2) Table IV-b for high-mounted stop lamps; and 
(3) Table IV-c for school bus signal lamps. The four sections of Table 
V, Visibility Requirements of Installed Lighting Devices, now include: 
(1) Table V-a for backup lamps, high-mounted stop lamps, and school bus 
signal lamps; (2) Table V-b which contains the lens area option for 
turn signal lamps, stop lamps, taillamps, and parking lamps; (3) Table 
V-c which has the luminous intensity option for turn signal lamps, stop 
lamps, taillamps, and parking lamps; and (4) Table V-d that has older 
alternative requirements for turn signal lamps, stop lamps, and 
taillamps.
    Table VI, Front Turn Signal Lamp Photometry Requirements, was split 
into two sections in the final rule. Table VI-a contains the base front 
turn signal lamp photometry requirements and also the values for 2\1/2\ 
times the base photometry requirements while Table IV-b contains values 
for 2 times the base photometry requirements and 1 the base photometry 
requirements
    New Table XIII consisting of: (1) Table XIII-a, Motorcycle Turn 
Signal Lamp Alternative Photometry Requirements, and (2) Table XIII-b, 
Motor Driven Cycle Alternative Photometry Requirements, includes the 
stop lamp requirements for certain motor driven cycles previously part 
of Table IX in the NPRM, as well as alternative turn signal 
requirements for motorcycles noted in paragraph S7.1.1.1 and S7.1.2.1 
of the NPRM but not previously tabularized. The three sections of Table 
XVI are now: (1) Table XVI-a, Reflex Reflector Photometry Requirements, 
(2) Table XVI-b, Additional Photometry Requirements for Conspicuity 
Reflex Reflectors, and (3) Table XVI-c, Retroreflective Sheeting 
Photometry Requirements.
    Table XIX has been split into Tables XIX-a, containing photometric 
requirements for lower beam patterns LB1M, LB1V, LB2M, and LB2V. Table 
XIX-b contains requirements for lower beam patterns LB3M, LB3V, LB4M, 
and LB5M while Table XIX-c contains requirements for lower beam pattern 
LB4V.
    As mentioned previously, the ASSN/AAM response proposed a common, 
templated organizational format for the individual lamp sections and 
expansion of their content to include 14 subsections representing 
specific requirements. The requirements that they suggested be included 
in each section include: (1) Number, (2) color of light, (3) 
arrangement, (4) position, (5) geometric visibility, (6) orientation, 
(7) effective projected luminous lens area, (8) electrical, (9) tell 
tale, (10) marking requirements, (11) other provisions, (12) plastic 
materials, (13) photometry, and (14) physical tests. Implementing this 
request presents a dilemma for several reasons. First, most of the 
requirements suggested to be listed in individual lamp sections are 
already stated in parts of Table I, Table IV, and Table V. Table I of 
the NPRM is an expansion of Tables I, II, III, and IV of the current 
version of Standard No. 108, tables which have been part of the 
standard for decades. The agency rarely receives questions or 
complaints about regulatory content contained in Tables I through IV, 
but instead, they are often considered the most useful feature of the 
current version. We received no comments, including the ASSN/AAM 
submission, which suggested elimination of Table I.
    We also believe that the suggestion of ASSN/AAM to remove the 
activation requirements from Table I and place them all in a new 
section titled ``Electrical'' was without merit. The activation 
requirements of the various types of lamps, like the other categories 
listed in Table I, are primarily vehicle-level requirements rather than 
device-level requirements, and are best presented along with those 
other requirements.
    Table V of the NPRM is a restatement of Figures 19 and 20 of the 
current version of Standard No. 108, which were added in a final rule 
\7\ published on August 11, 2004 which promulgated the current 
visibility requirements. The agency decided that it would not be 
appropriate to disperse the visibility requirements of Table V (and 
likewise the effective projected luminous lens area requirements of 
Table IV) into individual lamp sections. The primary reason was that in 
real world situations, many lamp functions are combined with other lamp 
functions, very often optically combined. It is not unusual for a 
vehicle to have a combination rear lamp where the taillamp, stop lamp, 
and rear turn signal lamp functions are optically combined. The same 
holds true for front turn signal lamps and parking lamps. The 
presentation of visibility requirements for all regulated lamp 
functions together in Table IV allows regulated parties to quickly 
determine the appropriate requirements for such combination lamps and 
perhaps aid the decision about which visibility alternative to use for 
certification.
---------------------------------------------------------------------------

    \7\ 69 FR 48805 (Aug. 11, 2004) (Docket No. 2004-18794-1).
---------------------------------------------------------------------------

    The decision to leave Tables I, IV, and V intact in the final rule 
means that adopting the ASSN/AAM template for individual lamp sections 
would result in large scale duplication of requirements in Standard No. 
108. Duplication of the same requirement in more than one location in a 
regulatory document has the potential for

[[Page 68240]]

unintended consequences. We intended to avoid those consequences by 
having each discrete requirement only stated once in Standard No. 
108.\8\
---------------------------------------------------------------------------

    \8\ See the discussions of Table II and Table IX for 
explanations of existing duplicated requirements in the current 
version of FMVSS No. 108.
---------------------------------------------------------------------------

    Therefore, to be responsive to the request of ASSN/AAM concerning 
the format of individual lamp sections while still maintaining the 
integrity of the standard by having only a single statement of each 
requirement, we have adopted the use of pointing statements. These 
pointing statements appear in those subsections of each lamp section 
where a requirement does exist but is stated in another location of the 
standard. For instance, in paragraph S7.4 pertaining to side marker 
lamps, subsections 7.4.1 Number, 7.4.2 Color of light, 7.4.3 Mounting 
location, 7.4.4 Mounting height, and 7.4.5 Activation, all conclude 
with the pointing statement ``See Tables I-a, I-b, and I-c.'' 
Similarly, S7.4.9 Markings points to S6.5 for details of the applicable 
marking requirements. S7.4.6 Effective projected luminous lens area, 
S7.4.7 Visibility, S7.4.8 Indicator, S7.4.10 Spacing to other lamps, 
S7.4.11 Multiple compartment and multiple lamps, and S7.4.12 Ratio all 
conclude with the term ``No requirement'' indicating a requirement for 
those specific items of lamp performance does not exist in Standard No. 
108.
    The entire content of Table III of the NPRM, dealing with 
conspicuity systems, was moved to paragraph S8.2 of the final rule. A 
new Table III was created to serve as a compilation of pointing 
statements directed to the locations within the final rule where 
marking requirements reside. While some headlamp marking requirements 
were relocated to paragraph S6.5 in the final rule, a number of other 
marking requirements continue to be dispersed within the document. In 
these cases, we have decided that the marking requirements are best 
located near the specific items to which they apply. However, these 
locations are all identified in Table III and consultation with this 
table should lead the user to all applicable marking requirements.
    Grote suggested that lengthy paragraphs of regulatory text be 
simplified by splitting them into separately numbered sub-paragraphs, 
particularly where the requirements were diverse. In a number of 
instances, we have been able to create such separation. Regulatory 
provisions (including renumbered paragraphs) where this has been done 
include: S6.1.3, S6.1.4.2, S6.1.5.2, S6.2.6, S6.5.3.3, S6.5.3.4, S6.6, 
S7.1.1.11, S7.1.1.12, S7.1.2.11, S7.1.2.12, S7.1.3, S7.2.11, S7.3.11, 
S7.3.12, S7.3.15, S7.7.13, S7.7.15, S7.9.14, S8.2.1, S8.2.2.3, S9.3.4, 
S9.8, S10.14.2, S10.17.1.1, S10.17.1.2, S10.17.1.3, S13, S14.1.4, 
S14.2.1, S14.2.3, S14.2.4, S14.2.5, S14.4.1, S14.4.2, S14.5, S14.6, 
S14.7, and S14.9. We have included the term ``split for clarity'' or 
similar language, often parenthetically, numerous places in the 
discussion of revisions to note where a section of text from the NPRM 
was divided into several smaller sub-sections in the final rule but not 
otherwise revised.
    Guide submitted numerous suggestions for reorganizing the NPRM by 
the reassignment of certain paragraphs within the organizational 
framework of the NPRM. In several instances, the agency concluded that 
the Guide suggestion proved to be a more appropriate location for a 
paragraph than the location proposed in the NPRM. We have noted these 
reassignments in our discussion (but without attribution to a Guide 
suggestion in some cases). This has caused numerous changes in the 
paragraph numbers throughout the regulatory text. Where a requirement 
in the final rule was identified differently in the NPRM, we have 
indicated the previous paragraph number in the revision summary.
    A number of Guide's suggested reassignments were not adopted, 
because we decided that the applicable textual provisions were already 
situated in the most appropriate location. Again, we did not mention 
every such rejection of Guide's suggested ordering or our reasoning for 
such decisions. While we believe that the final rule's organizational 
structure is the optimal choice, we recognize that it is not the only 
choice. Often, some of the requirements of Standard No. 108 intermix 
several attributes of lamps. Such an example is paragraph S7.11.2.1 
which contains requirements for a DRL spaced near a turn signal lamp 
(e.g., considerations for the actual separation distance, the luminous 
intensity of both the DRL and the turn signal lamp, whether the DRL is 
optically combined with a lower beam headlamp, and the activation 
properties of both the DRL and turn signal lamp). Requirements such as 
these do not fit neatly into a Mounting Location section or an 
Activation section, and their essence would not survive dispersion of 
the component requirements into these sections because of their 
interdependence on several diverse attributes.
    Another such situation involves the presentation of the 
requirements for conspicuity systems. The content of Table III of the 
NPRM was moved to paragraph S8.2 of the regulatory text to provide a 
more comprehensible presentation format. An argument could be made that 
this content should be split into two portions, one portion describing 
how conspicuity material is spaced and arranged and another portion 
describing where conspicuity material is to be placed on applicable 
vehicles. If this apportionment were made, the first portion could be 
considered a device-level requirement and the second portion a vehicle-
level requirement. Dispersing conspicuity system content in this way 
may seem correct from an organizational perspective, but would be in 
conflict with the goals of the rewrite of Standard No. 108 to present 
the requirements in a straight forward and logical manner.
    Our guiding principle in organizing the structure of the FMVSS No. 
108 final rule was to attempt to locate each requirement in the place 
where a user would be most likely to look for it. Accordingly, the 
final rule has been organized with the following major sections:

S1 Scope.
S2 Purpose.
S3 Application.
S4 Definitions.
S5 References to SAE publications.
S6 Vehicle requirements.
S7 Signal lamp requirements.
S8 Reflective device requirements.
S9 Associated equipment requirements.
S10 Headlighting system requirements.
S11 Replaceable light source requirements.
S12 Headlamp concealment device requirements.
S13 Replaceable headlamp lens requirements.
S14 Physical and photometry test procedures and performance 
requirements.

4. Suggestions Beyond the Scope of the Rewrite

Units of Measurements
    Several comments were received concerning the way quantities in the 
NPRM were measured, in terms of units. In some cases, measurements were 
only in metric units, others in only English units, and still others 
dual-dimensioned with both metric and English units. We note that this 
situation currently exists within Standard No. 108 and the SAE 
standards and Recommended Practices incorporated by reference. Such 
perceived inconsistencies in the final rule are the result of the 
agency's decision to make no substantive changes to Standard No. 108 
during the rewrite process. This means stating measurements in their 
original form consistent with their original source documents, instead 
of attempting to convert and standardize the units.
    ASSN preferred dual English/metric measurements for every quantity 
and requested that both be provided in the final rule. The commenter 
also preferred that linear measurements be expressed in both inches and 
centimeters. AAM requested dual units with metric units followed by 
English units and the use of direct conversions to establish those 
measurements that were only stated in one unit in the NPRM. Nissan 
argued that in recent rulemakings, the agency has consistently listed 
measurements using metric units with English units referenced 
parenthetically. Nissan preferred linear measurements that were in 
millimeters, except for photometric test distances which should remain 
dimensioned in meters. Conversely, Grote recommended that measurements 
be expressed in inches followed by centimeters in parentheses, 
believing that the vast majority of current users continue to use 
English measurements. SEMA also supported dual units of measurements 
with a preference for centimeters rather than millimeters. In 
supplemental comments, AAM/ASSN requested all quantities in FMVSS No. 
108 that are not now metric be converted to metric pursuant to 
Executive Order 12770 (Metric Usage in Federal Government Programs).
    The FMVSS No. 108 rewrite is considered an administrative action 
because existing requirements and obligations are not being increased, 
decreased, or substantively modified. The agency has decided that 
converting values and providing dual-dimensions is outside the scope of 
this final rule. The conversion process, in some cases, would result in 
substantive change in the current requirements of the standard. This is 
because such conversions rarely result in a whole number equivalent, 
but more likely in an unwieldy value with more digits than the value it 
was converted from. The converted unit may have a non-exact value 
requiring it to be truncated after several digits. Such rounding may 
have little effect on some attributes but significant effect on others. 
An additional complication is that some currently dual-dimensioned 
values in FMVSS No. 108 are not exact equivalents. For instance, the 
air pressure required to be applied to the replaceable light source in 
the replaceable light source pressure test is expressed as 70 KPa (10 
psig). However, the English equivalent of 70 KPa is 10.152641661 psig 
and the metric equivalent of 10 psig is 68.9475728 KPa. Thus, a user 
may conclude that a replaceable light source may be compliant with the 
standard if it withstands a pressure of 68.9475728 KPa and not 70 KPa.
    Additionally, the comments received in response to the NPRM show 
that users of FMVSS No. 108 do not have a consistent preference for a 
particular approach regarding units of measurement. In consideration of 
our principle not to change any existing requirements, as well as the 
wide range of opinions on the best approach for dual-dimensioning, the 
agency decided to present values consistent with the current standard 
instead of choosing one of the suggested options.
Photometric Maps
    As previously mentioned, the AAM/ASSN supplementary comments, the 
ASSN initial comments, and the NAL comments recommend inclusion of a 
number of new graphical maps that would show details of the 
requirements for the various photometric test patterns. The signal lamp 
maps would show the position of each individual test point and how 
those points are combined into groups. The headlamp maps would show 
individual test points, linear test elements, and zonal test elements.
    In reviewing the suggested graphical maps, it was unclear which 
test points were part of which zone. Furthermore, such maps are beyond 
the scope of the administrative rewrite. In addition, there were no 
compelling arguments presented addressing how their inclusion would 
advance the goals of the rewrite. Adding such graphical maps would 
provide redundant information, significantly increasing the risk of 
potentially conflicting requirements, and likely generate numerous 
interpretation requests, especially if users were confused by the new 
graphs.
    That is not to say that these types of illustrations have no value. 
They seem particularly well suited for use by design and manufacturing 
organizations use in their internal design standards or photometric 
test procedures documents. Standard No. 108, like all Federal Motor 
Vehicle Safety Standards, strives to present regulatory requirements in 
the clearest way possible. It is not intended to serve as an all-
inclusive working guide for designing, testing, or manufacturing lamps, 
reflective devices, or associated equipment. NHTSA

[[Page 68242]]

anticipates that user organizations will carefully incorporate the 
requirements of FMVSS No. 108 into their internal working documents.
Requests for New or Revised Definitions
    Commenters requested inclusion in the final rule of numerous 
definitions for specific terms. These include: ``center (of item),'' 
``fixed body panel,'' ``four lamp type headlamp,'' ``hazard warning 
lamps,'' ``obstruction,'' ``rigid part of vehicle,'' ``separately 
lighted areas,'' ``two lamp type headlamp,'' ``special tools,'' ``tools 
ordinarily available,'' ``supplemental lamp,'' and ``auxiliary lamp.'' 
There was also a suggestion for a revised definition for the term 
``color bleeding,'' alleging it could be mistaken for the term ``light 
bleed.'' A suggestion was also submitted for addition of definitions of 
all lamp types mentioned in the current version of FMVSS No. 108, with 
the specific example of fog lamp.
    In its initial submission, AAM suggested the final rule use the 
term ``* * * light source optical centers * * *'' in place of the term 
``* * * light sources * * *'' and the term ``* * * optical centers * * 
*'' in place of the term ``* * * optical axes * * *'' as revisions that 
would be technology-neutral in the specific case of a series wired 
array of LEDs being considered a single light source per the January 5, 
2006 letter of interpretation to AMECA.\9\ There were also suggestions 
that the term ``lighted section'' be used exclusively and in place of 
``multiple compartment'' and ``multiple lighted area.'' Adopting any of 
these suggestions would have been a substantive action which would be 
beyond the defined scope of this rewrite. For this reason we have not 
adopted any of these suggested modifications in the final rule.

5. Suggestions Within the Scope of the Rewrite
SAE Documents
    A significant initiative of the FMVSS No. 108 rewrite was the 
incorporation of requirements contained in SAE Standards and 
Recommended Practices (currently incorporated by reference or sub-
reference) directly into the body of the standard. The current version 
of Standard No. 108 relies heavily on the content of numerous SAE 
documents. It contains over 100 references to some 35 different SAE 
documents, many of which were issued in the 1960s. Some of these 
documents are incorporated in their entirety, whereas only portions of 
others are cited. The NPRM integrated much of the content of these SAE 
document directly into the regulatory language, resulting in only eight 
SAE documents continuing to be incorporated by reference.
    Generally commenters supported this action. SEMA requested that all 
referenced and sub-referenced SAE documents be included in the 
regulatory text of the final rule. While total elimination of documents 
incorporated by reference proved to be impractical, we did eliminate 
references to three additional SAE documents in the final rule as 
discussed below. We also restored a reference to SAE J567b, Bulb 
Sockets, in S14.2.1.6.2 of the final rule based upon comments by 
Calcoast. This reference exists in Footnotes 2 and 3, which follow 
Table IV, of the current version of FMVSS No. 108, but was eliminated 
in the NPRM. We agree with Calcoast that the exemption permitted in 
these footnotes stating that bulbs not listed in SAE J573d, Lamp Bulbs 
and Sealed Units, December 1968, are not required to use a socket that 
conforms to the requirements of SAE J567b, Bulb Sockets, April 1964, is 
needed in the final rule.
    SAE J577, Vibration Test Machine, April 1964, has been replicated 
as Figure 21, and all references to SAE J577 have been removed from the 
final rule. SAE J823b, Flasher Test Equipment, April 1968, describes a 
standard test circuit to be used in the performance testing of 
vehicular hazard warning signal flashers and turn signal flashers. This 
SAE standard also has specifications for power supplies used in these 
tests and describes the circuit adjustments necessary to perform valid 
tests. We have chosen to incorporate the content of SAE J823b into the 
final rule. New Figure 22, Flasher Standard Test Circuit, provides the 
test circuit schematic diagram from Figure 1 of SAE J823b. Paragraph 
S14.9.3.1 of the final rule states requirements for circuit adjustments 
applicable to flasher tests, and paragraph S14.9.3.2 provides separate 
power supply specifications for the various flasher performance tests. 
With the inclusion of paragraph S14.9.3 and Figure 22 in the final 
rule, all references to SAE J823b have been deleted.
    SAE J588e, Turn Signal Lamps, September 1970, incorporated by 
reference in FMVSS No. 108, is referenced in paragraph S5.1.1.1 of the 
current version of the standard solely to establish requirements for 
double-sided turn signal lamps installed on truck tractors. It was 
eliminated from the final rule by incorporating the content of 
paragraph 3.4 and a portion of paragraph 3.9.1 of SAE J588e into 
paragraph S6.1.1.3 of the NPRM. The remaining portion of paragraph 
3.9.1 was incorporated in Table VII, Rear Turn Signal Lamp Photometry 
Requirements, of the NPRM by revision to Footnote 6.
    The revised paragraph S6.1.1.3 now reads, `` * * * A truck tractor 
need not be equipped with turn signal lamps mounted on the rear if the 
turn signal lamps at or near the front are of double-face construction 
and are located such that they meet the photometric requirements for 
double-faced turn signal lamps specified in Footnote 6 of Table VII.'' 
Continuing, paragraph S6.1.1.3.1 states, ``The flashing signal from a 
double-faced signal lamp must not be obliterated when subjected to 
external light rays from either in front or behind, at any and all 
angles.'' The revised Footnote 6 to Table VII now states, ``A double-
faced turn signal lamp installed as described in paragraph S6.1.1.3 on 
a truck tractor need only meet the photometric requirements for a left 
side lamp where the lamp is mounted on the left side of the vehicle, 
and for a right side lamp where the lamp is mounted on the right side 
of the vehicle.''
    This same SAE standard, J588e, Turn Signal Lamps, September 1970, 
is cited in the current version of FMVSS No. 108 as containing the 
requirements for the illuminated pilot indicator for turn signal lamp 
failure. The NPRM had erroneously stated the requirements from SAE J588 
NOV84, Turn Signal Lamps. Paragraph S9.3 of the final rule now 
correctly states the illuminated area of the indicator and the 
acceptable modes of indication. Consistent with these changes, all 
references to SAE J588e have been removed from the standard.
    We undertook the effort to eliminate these additional SAE 
references in the final rule in part because the nature of some 
comments suggested that the relationship between FMVSS No. 108 and its 
incorporated SAE documents causes significant confusion.
    One example of such confusion is found in the comments of Grote and 
Koito in reference to the limitations in applying reduced photometric 
requirements to adjacent front and rear side marker lamps. This section 
is based upon paragraph S5.1.1.8 of the current version of Standard No. 
108 which states, ``For each motor vehicle less than 30 feet in overall 
length, the photometric minimum candlepower \10\ requirements for side 
marker lamps specified in SAE Standard J592e,

[[Page 68243]]

Clearance, Side Marker, and Identification Lamps, July 1972, may be met 
for all inboard test points at a distance of 15 feet from the vehicle 
and on a vertical plane that is perpendicular to the longitudinal axis 
of the vehicle and located midway between the front and rear side 
marker lamps.'' In this case, the limitation of vehicles less than 30 
feet in overall length recognizes that those vehicles are ones where 
intermediate side marker lamps (and intermediate side reflex 
reflectors) are not required to be installed. Table 1 of SAE J592e, 
detailing the photometric requirements of side marker lamps, also 
contains a footnote ``b'' further limiting the vehicles where reduced 
photometric requirements can be applied. Footnote ``b'' states that, 
``The requirements for side markers used on vehicles less than 80 
inches (2 meters) wide may be met for inboard test points * * * '' This 
vehicle width limitation is reflected in Footnote 1 of Table X. This is 
an example where the text of an incorporated SAE document applies 
limitations beyond those contained in the text of FMVSS No. 108.
---------------------------------------------------------------------------

    \10\ The term ``candlepower'' used in this context means the 
contemporary unit of measurement used to express the luminous 
intensity attribute.
---------------------------------------------------------------------------

    Another example is illustrated in the comments by AAM and Koito 
about the spatial relationship between front turn signal lamps and 
certain other front-mounted lamps and the photometric requirements the 
relationship imposes on the front turn signal lamp as stated in 
paragraph S7.1.1.2 of the NPRM (S7.1.1.10 of the final rule). Current 
FMVSS No. 108, at paragraph S5.3.1.7, imposes a multiplier of 2.5 on 
minimum photometric intensity requirements for a front turn signal lamp 
mounted less than 100 mm from the lighted edge of a lower beam 
headlamp. Turn signal lamps are also required to be designed to conform 
to referenced standards SAE J588 NOV84 for vehicles less than 2032 mm 
in overall width and SAE J1395 APR85 for vehicles 2032 mm or more in 
overall width. These documents provide, in paragraph 5.1.5.4 of SAE 
J588 and paragraphs 5.1.5.4, 5.1.5.5, and 5.1.5.6 of SAE J1395, 
additional photometric requirements for turn signal lamps based upon 
their construction. The method the turn signal lamp uses to project 
light (i.e., whether it primarily uses a reflector to direct light or 
not) determines how the relationship is measured between the turn 
signal lamp and the lower beam headlamp, or a surrogate lower beam 
headlamp such as an auxiliary lower beam headlamp or a fog lamp. Based 
upon this measurement, the turn signal lamp may be required to have a 
multiplier of 1.5, 2.0, or 2.5 times the minimum photometric intensity. 
Thus, it is possible for a turn signal lamp not to be required to have 
increased intensity based upon paragraph S5.3.1.7 of current FMVSS No. 
108 but still be required to have increased intensity because of its 
construction or proximity to another front lamp, such as a fog lamp. 
This is an example where an incorporated SAE document imposes 
requirements beyond those explicitly stated in the regulatory text of 
Standard No. 108.\11\
---------------------------------------------------------------------------

    \11\ The subject of turn signal lamp photometric requirements 
based upon spacing to other front lamps is discussed in several 
interpretations such as Matsui (9/20/95).
---------------------------------------------------------------------------

    In its comments, AAM stated that FMVSS No. 108 has never contained 
a requirement for a vehicular hazard warning signal pilot indicator as 
contained in paragraph S6.6 of the NPRM (paragraph S9.8 of the final 
rule). We note that this requirement came from SAE J910, Vehicular 
Hazard Warning Signal Operating Unit, January 1966, and SAE J945, 
Vehicular Hazard Warning Flasher, February 1966, both incorporated by 
reference in Tables I and III of the current version of FMVSS No. 108. 
The requirements from SAE J910 contained in paragraph 5 detail how the 
pilot indicator is to operate, how it can be combined with the turn 
signal indicator, and the size and color of a dedicated vehicular 
hazard warning signal pilot indicator. The requirements from SAE J945 
describe how the means of providing the indication can be incorporated 
into the flasher if it functions under all test conditions applied to 
the flasher and how an audible indication can be used in conjunction 
with the visible indication. This is an example where incorporated SAE 
documents contain a requirement that is not expressly stated in the 
text of FMVSS No. 108.
    AAM also stated in its comments that only the lighting equipment 
requirements of SAE J587 OCT81, License Plate Lamps (Rear Registration 
Plate Lamps), are incorporated by reference in Standard No. 108 (i.e., 
in paragraph S5.1.1 of the current version). AAM argued that a license 
plate holder is not an item of lighting equipment and that requirements 
for the holder would also apply to a front license plate holder. In 
response, we note that SAE J587 OCT81 does contain specific 
requirements for a license plate holder and its relationship with the 
license plate, the surface the vehicle stands on, and the license plate 
lamp. The performance of a license plate lamp is dependent upon its 
physical relationship with the license plate. The license plate must be 
secured in position to evaluate this performance. To alleviate AAM's 
concern with application of the requirement to a front license plate 
holder, we have revised the text of paragraph S6.6.3 of the final rule 
(paragraph S6.1.1 of the NPRM) to state, ``Each rear license plate 
holder must be designed and constructed to provide a substantial plane 
surface on which to mount the plate. The plane of the license plate 
mounting surface and the plane on which the vehicle stands must be 
perpendicular within  15[deg] '' (emphasis added).
    Grote commented that lamps designed to conform to SAE J1395 APR85, 
Turn Signal Lamps for use on Motor Vehicles 2032 mm or more in Overall 
Width, and SAE J1398 MAY85, Stop Lamps for use on Motor Vehicles 2032 
mm or more in Overall Width, incorporated by reference in Table I of 
the current version of FMVSS No. 108 for use on multipurpose passenger 
vehicles, trucks, trailers, and buses, of 80 or more inches in overall 
width, could also be used on vehicles less than 80 inches (2032 mm) 
overall width, without meeting the requirements listed in Table III for 
these lamps. Grote based its comment on a statement in the Scope of SAE 
J1395 stating that, ``Turn signal lamps conforming to this report may 
also be used on vehicles less than 2032 mm in overall width.'' The 
Scope of SAE J1398 has a similar statement concerning stop lamps. This 
assertion is simply not correct. Table III of the existing version of 
Standard No. 108 applies to all passenger cars and motorcycles, and 
multipurpose passenger vehicles, trucks, buses and trailers of less 
than 80 inches (2032 mm) in overall width. Table III clearly requires 
turn signal lamps to comply with SAE J588 NOV84 and stop lamps to 
comply with SAE J586 FEB84. Therefore, manufacturers may choose to 
design their lamps to also comply, respectively, with SAE J1395 APR85 
and SAE J1398 MAY85, but they also must be designed to comply, 
respectively, with SAE J588 NOV84 and SAE J586 FEB84. We do not agree 
with the argument that compliance with only SAE J1395 APR85 and SAE 
J1398 MAY85, respectively, is permitted, because this clearly 
contradicts the language in the existing regulatory text.
    Table III of the current version of FMVSS No. 108 requires that all 
passenger cars and motorcycles, and multipurpose passenger vehicles, 
trucks, trailers, and buses, of less than 80 inches (2032 mm) in 
overall width must be equipped with lamps designed to conform to the 
requirements of SAE J588 NOV84, Turn Signal Lamps for use on Motor 
Vehicles Less Than 2032 mm

[[Page 68244]]

in Overall Width, and SAE J586 FEB84, Stop Lamps for use on Motor 
Vehicles Less Than 2032 mm in Overall Width. Thus, if a turn signal 
lamp or stop lamp is not designed to conform with SAE J588 NOV84 or SAE 
J586 FEB84 respectively, it cannot be used on any passenger car or 
motorcycle or on any multipurpose passenger vehicle, truck, trailer, or 
bus of less than 80 inches in overall width, no matter whether it also 
is designed to conform to SAE J1395 APR85 or SAE J1398 MAY85. The 
explicit requirements of FMVSS No. 108 prevail over any seemingly 
contradictory language of an incorporated third-party document.
    Observing the confusion that exists because the current version of 
Standard No. 108 relies so heavily upon reference to third-party 
documents, we are convinced that our action to remove those references 
to the maximum extent possible was a correct decision. Remaining 
references to SAE documents in the final rule include:

Cited Interpretations
    In the rewrite proposal, the agency integrated the clarifications 
provided by key letters of interpretation into the regulatory text of 
the standard. The criteria used in determining whether an 
interpretation was significant focused on whether it provided value in 
clarifying the provisions in the standard. In the vast majority of 
cases, past requests for interpretation have identified questions 
regarding applicability of certain provisions of the standard to 
specific design configurations. However, influential interpretations 
that clarified provisions of the standard, and continue to provide 
guidance to various parties beyond the original requestor, were 
believed to be particularly useful additions to the regulatory text. In 
the NPRM, the agency solicited public comment about additional 
interpretations that might be included in the final rule.
    In their submissions, several commenters mentioned specific 
interpretations of FMVSS No. 108 as candidates for incorporation in the 
regulatory text of the final rule. In two instances, we decided that 
the cited interpretations would make the standard more precise and 
added them to the final rule. The two interpretations are discussed 
below. Several commenters suggested other potential interpretations for 
inclusion into the final rule; however the agency decided that none of 
these provided enough value in clarifying the provisions of FMVSS No. 
108.
    Nissan suggested that inclusion of the June 18, 1985 interpretation 
to Mr. Nakaya \12\ would more precisely define where the measurement of 
the height of a high-mounted stop lamp should be made with respect to 
the rear window of a passenger car. A more detailed description of this 
interpretation is found in the discussion of revised paragraph 
S6.1.3.2.1 of the final rule.
---------------------------------------------------------------------------

    \12\ http://isearch.nhtsa.gov/gm/85/1985-02.42.html_____________________________________-

    A suggestion of TTMA was to incorporate an interpretative rule \13\ 
published in 1999 into the standard. This interpretative rule 
quantifies the ``as near the top as practicable'' mounting requirement 
that applies to clearance lamps and identification lamps mounted on a 
vehicle with cargo doors. That rule states that NHTSA will presume it 
practical to mount these lamps above the cargo doors when the header 
above those doors extends at least 25 mm (1 inch) above them. A more 
detailed discussion of this issue is found in the discussion of Table 
I.

Revisions to the Proposal
S1 Through S3
    There were no comments submitted that related to S1, S2, or S3.
S4 Definitions
    AAM objected to mounting and spacing criteria being part of the 
definitions of a clearance lamp, identification lamp, and side marker 
lamp. In response, we note that all three of these definitions are 
faithful to the applicable, long-referenced, SAE standards whose 
content we have included in both the proposal and final rule text. 
These mounting and spacing criteria serve to clarify the spatial 
function of the lamps and are appropriate parts of the definitions. 
Therefore, we are keeping these criteria in the final rule.
    We removed the third sentence from the definition of ``effective 
projected luminous lens area,'' stating the term ``functional lighted 
lens area'' appearing in any SAE document had an identical meaning. The 
single instance of the term ``functional lighted (lens) area'' 
appearing in the NPRM was in paragraph S7.1.1.2.2 (S7.1.1.10.3 in the 
final rule) in reference to the procedure to determine the measurement 
point for a front turn signal lamp with a reflector. We replaced 
``functional lighted (lens) area'' in paragraph S7.1.1.10.3 with 
``effective projected luminous lens area'' and were thereby able to 
remove any reference to ``functional lighted lens area'' in the 
standard.
    Nissan observed that the definitions for ``mechanically aimable 
headlamp'' and ``material'' were not in alphabetical order in the NPRM. 
We have corrected this in the final rule.
    GE commented that the definition of ``replaceable light source'' in 
the NPRM was not identical to that of the current version of FMVSS No. 
108. As stated in the NPRM ``replaceable light source,'' means an 
assembly of a capsule, base, and terminals manufactured as a light 
source for an upper and/or lower beam of a replaceable bulb headlamp 
that is designed to conform to the requirements of Appendix A or 
Appendix B of 49 CFR part 564, Replaceable Light Source Information. 
The italicized text was added to the definition included in the current 
version of FMVSS No. 108 as part of an attempt to clarify that integral 
beam and replaceable bulb headlamps are allowed to incorporate 
``replaceable light sources'' that are used for purposes other than 
headlighting. However these ``replaceable light sources'' are not those 
defined in S4, but rather ones typically used for non-headlighting 
functions such as turn signal lamps, parking lamps, and front side 
marker lamps. In the final rule, as explained later in the discussion 
of S10 Headlighting system requirements, we have decided to address 
this issue by revising how these non-headlighting light sources were 
described. Because the revisions in language in S10 should eliminate 
confusion between headlighting and non-headlighting replaceable light 
sources, there is no need to change the definition in S4 and it is 
identical in the

[[Page 68245]]

final rule to that of the current version of FMVSS No. 108.
    Nissan commented that the definitions for ``vehicular hazard 
warning signal flasher'' from SAE J945, Vehicular Hazard Warning Signal 
Flasher, February 1966, and for ``vehicular hazard warning signal 
operating unit'' from SAE J910, Vehicular Hazard Warning Signal 
Operating Unit, January 1966, described the function of the hazard 
warning signal system in slightly different ways. Nissan contended, and 
we agree, that the description of the operation of the hazard warning 
signal system should be consistent. Therefore, we have revised the 
definition of ``vehicular hazard warning signal flasher'' from `` * * * 
means a device which, as long as it is turned on, causes all the 
required hazard warning lamps to flash'' to `` * * * means a device 
which, as long as it is turned on, causes all the required turn signal 
lamps to flash.'' Similarly the definition of the ``vehicular hazard 
warning signal operating unit'' was revised from `` * * * means a 
driver controlled device which causes all turn signal lamps, or other 
hazard warning lamps, to flash simultaneously to indicate to 
approaching drivers the presence of a vehicular hazard'' to `` * * * 
means a driver controlled device which causes all required turn signal 
lamps to flash simultaneously to indicate to approaching drivers the 
presence of a vehicular hazard''. This revision recognizes that the 
hazard warning signal of paragraph S6.1.5.1 only requires simultaneous 
flashing of sufficient turn signal lamps to meet the turn signal 
photometric requirements of Standard No. 108.
S5 References to SAE Publications
    In paragraph S5.2 of the NPRM we stated that ``A complete list of 
all SAE publications incorporated by reference in this standard are 
indexed at 49 CFR 571.5(j)''. This inclusion was in anticipation of a 
final rule based upon a NPRM \14\ that would have established 49 CFR 
571(j) to contain this list. This final rule has not been issued. 
Therefore, we have deleted this reference from the final rule.
---------------------------------------------------------------------------

    \14\ 70 FR 36094, (June 22, 2005)(Docket No. 2005-21600-1).
---------------------------------------------------------------------------

    AAM requested that the word ``required'' be inserted into the first 
sentence of paragraph S5.1 between the words ``Each'' and ``lamp'' to 
be faithful to paragraph S5.1.1 of the current version of FMVSS No. 108 
containing provisions for lamps, reflective devices, and associated 
equipment to be designed to comply with specific SAE Standards and 
Recommended Practices. We agree and have revised the final rule.
S6 Vehicle Requirements
    Proposed paragraph S6.1.1.1.1, allowing conspicuity material on a 
trailer to also serve as the required reflex reflectors if the 
conspicuity material was placed at the required locations of the reflex 
reflectors, has been relocated into the Reflex Reflectors portion of 
Table I-b of the final rule.
    Paragraph S6.1.1.3 was modified as stated in the SAE Documents 
section above to fully integrate the requirements of SAE J588e, Turn 
Signal Lamps, September 1970, relating to the use of double-faced turn 
signal lamps on truck tractors. This amendment also required a revision 
to Table XII and its Footnote 6 as well as the addition of paragraph 
3.9.1 of SAE J588e as paragraph S6.1.1.3 of FMVSS No. 108 and paragraph 
3.4 of SAE J588e as paragraph S6.1.1.3.1 of FMVSS No. 108.
    Paragraph S6.1.1.4 of the final rule, (paragraph S6.2.4 of the 
NPRM), was moved into the Vehicle requirements section based upon the 
Guide comment that it was a more appropriate location than the 
Impairment section. A typographical correction was also made to clarify 
that a parking lamp or a fog lamp may not be used as a DRL. This 
correction now results in language that is faithful to the current 
version of FMVSS No. 108 at paragraph S5.5.11(a).
    Paragraph S6.1.1.4, Hazard warning lamps, of the NPRM describing 
activation provisions for hazard warning lamps was moved to the 
Activation section where it became paragraph S6.1.5.1 in the final 
rule.
    The phrase ``fixed body panel'' in proposed paragraph S6.1.3.1 was 
objected to by Koito as being more restrictive than the phrase ``rigid 
part'' which is used in the current version of FMVSS No. 108 at 
paragraph S5.3. We have decided to retain ``rigid part'' in the final 
rule to be faithful to the original language and meaning. The phrase `` 
* * * the mounting location and * * * '' has been added to paragraph 
S6.1.3.1 ahead of ``height'' to be consistent with the references to 
Tables I, II, III, and IV of the current version of FMVSS No. 108 as 
referenced at paragraph S5.3 of that document. This clarification was 
recommended by Guide.
    Guide also suggested that the requirements of the second sentence 
of paragraph S6.1.3 of the NPRM, which becomes paragraph S6.1.3.2 of 
the final rule, deal more with photometry than lamp mounting location. 
We do not agree with this suggestion. This requirement deals with how 
to consider, for photometry purposes, the individual compartments or 
lamps of an array that consists of portions on both rigid and non-rigid 
parts of the vehicle as described in the July 12, 2000, letter of 
interpretation to Mr. King.\15\ Because this provision establishes 
photometric performance requirements based upon what kind of surface a 
lamp is mounted upon, its inclusion in the Mounting location section is 
appropriate. We have added a pointing statement in paragraphs 
S7.1.1.11.1 (front turn signal lamps), S7.1.2.11.1 (rear turn signal 
lamps), S7.2.11.1 (taillamps), and S7.3.11.1 (stop lamps) in the final 
rule to direct users to this requirement. Guide also stated that this 
section should also apply to the rear reflex reflector. However, as 
stated in several interpretations, reflex reflector requirements must 
be met by single reflectors, not a combination of separate reflectors. 
Supporting this position is the May 23, 2003 letter of interpretation 
to Mr. Babcock \16\ as well as the April 14, 2004 letter of 
interpretation to Mr. Strassburger.\17\

---------------------------------------------------------------------------

    Paragraph S6.1.4, License plate lamp, of the NPRM has been 
relocated to paragraph S6.1.3.3 of the final rule in recognition that 
it states a requirement for mounting location.
    Paragraphs S7.9.1, Accessibility, and S7.9.2 Interior mounting, 
(duplication at S6.1.3.2.2 deleted) of the NPRM referring to high-
mounted stop lamps (HMSL) were relocated in the final rule to be 
paragraphs S6.1.3.4.2 and S6.1.3.4.1 respectively. These requirements 
relate primarily to how the HMSL is mounted to the vehicle, so 
paragraph S6.1.3 is the most appropriate location in Standard No. 108 
for them.
    Guide commented that the content of paragraphs S8.1.3 and S8.1.4 of 
the NPRM, dealing with headlamp beam mounting, belonged in that part of 
Standard No. 108 related to lamp mounting location. We agree and have 
moved them intact to become paragraph S6.1.3.5 of the final rule.
    Grote, Guide, Innovative, TMA, and TTMA all noted the typographical 
error in paragraph S6.2.5 of the NPRM. Both the title and text of this 
section contained the phrase ``* * * auxiliary identification lamp * * 
*'' which should be ``* * * auxiliary lamp* * *'' The correction has 
been made in the final rule, and this requirement has been relocated to 
the Mounting location

[[Page 68246]]

section as paragraph S6.1.3.6, as it states a mounting limitation.
    Paragraph S6.1.3.2.1 of the NPRM becomes paragraph S6.1.4.1, High-
mounted stop lamp, in the final rule. Nissan suggested that the term 
``window'' in the text had been defined more precisely in the June 18, 
1985 letter of interpretation to Mr. Nakaya \18\ as ``glazing'' and 
suggested use of that term in the final rule. We agree and revised the 
text accordingly.
---------------------------------------------------------------------------

    \18\ http://isearch.nhtsa.gov/gm/85/1985-02.42.html_____________________________________-

    Guide commented that paragraph S6.1.5.1 of the NPRM, concerning 
optional activation of stop lamps by vehicle retarders, duplicated 
Table I. Upon review, we believe it is a duplication, and we have 
decided that Table I is the appropriate location for it. Therefore, in 
the final rule this allowance is included in the Stop lamp-Device 
Activation portion of Tables I-a, I-b, and I-c.
    We have relocated to paragraph S6.1.5.1 of the final rule the 
content of paragraph S6.1.1.4 of the NPRM stating requirements of the 
hazard warning signal. This is appropriate since, as we noted in our 
discussion of the definitions of vehicular hazard warning signal 
flasher and vehicular hazard warning signal operating unit, the only 
requirement of this system is simultaneous flashing of sufficient turn 
signal lamps to meet the turn signal photometric requirements of 
Standard No. 108.
    Another section relocated to S6.1.5, Activation, is paragraph 
S6.1.5.2 of the final rule, which details the requirements for 
simultaneous activation of lower beam and upper beam headlamps. These 
requirements had been included as paragraph S8.2 of the NPRM. We agree 
with the comment of Guide that this content was most appropriately 
located in the Activation section.
    We removed paragraph S6.2.3 of the NPRM, which addressed specific 
requirements for auxiliary lamps performing the function of a required 
lamp, from the final rule. Grote, Guide, SEMA, and TMA persuaded us 
that the proposed S6.2.3 contained language that was not faithful to 
the current version of FMVSS No. 108 and did not add to the 
understanding of impairment.
    Paragraph S14.2 of the NPRM was relocated to be paragraph S6.2.6 of 
the final rule. This section states the restrictions that apply to 
equipment in front of a headlamp lens. Paragraph S6.2, Impairment, was 
judged the most appropriate location for it. SEMA suggested revising 
the language of this section in a way that was inconsistent with the 
current version of Standard No. 108 by allowing obstructions if some 
undefined visibility requirement were met. This suggestion would be a 
substantive change outside the scope of this rewrite project, and, as 
such, was not adopted in the final rule.
    As previously mentioned, paragraph S6.2.4 of the NPRM stating the 
requirements for DRLs was relocated to be paragraph S6.1.1.4 of the 
final rule.
    The text of paragraph S6.3, Equipment combinations, of the final 
rule remains identical to that of the NPRM.
    Paragraph S6.4, titled Visibility and aiming in the NPRM, was re-
titled Lens area, visibility and aiming in the final rule, recognizing 
the lens area requirements of paragraph S6.4.1. References in paragraph 
S6.4 to Table IV were revised in the final rule to reference Table IV-
a, Table IV-b, or Table IV-c, as appropriate.
    AAM and Koito commented that the requirement of a manufacturer to 
irrevocably certify compliance to one of the visibility options of 
paragraph S6.4.3 was on a ``lamp function'' basis rather than a 
``lamp'' basis as stated in the NPRM. We agree and have revised the 
text of paragraph S6.4.3 accordingly to bring it in conformity to the 
final rule \19\ establishing these visibility requirements.

    \19\ 69 FR 48805 (August 11, 2004) (Docket No. 2004-18794).
---------------------------------------------------------------------------

    Nissan objected to the title of paragraph S6.4.4, SAE visibility 
alternative, of the NPRM stating they did not like the use of the term 
SAE as part of that title. Considering one of the goals of the FMVSS 
No. 108 rewrite was to reduce reliance upon third party documents, 
particularly SAE documents incorporated by reference, we have 
eliminated ``SAE'' from the paragraph S6.4.4 title in the final rule. 
The title of this section in the final rule is Legacy visibility 
alternative recognizing that it contains requirements that have long 
been a part of Standard No. 108.
    Nissan also commented that paragraph S6.4.5, Low-mounted lamps, 
duplicated requirements stated in footnotes to Tables V-b, V-c, VI, 
VII, VIII, IX, XI, XIV, XVI-a, and XVII. We agree with Nissan that 
these footnotes are the appropriate location for these requirements and 
have eliminated this subparagraph from the final rule.
    The addition of a new Table III to the final rule as a repository 
for listing the location in the regulatory text of each marking 
requirement of Standard No. 108 is noted in paragraph S6.5.
    AAM and Koito noted that the regulatory requirement identified in 
paragraph S6.5.1 of the NPRM for the ``DOT'' marking was stated as 
``the standard'' rather than ``49 U.S.C. 30115'' as stated in paragraph 
S7.2(a) of the current version of FMVSS No. 108. We have revised the 
text of this section in the final rule to be faithful to the existing 
language.
    Paragraph S6.5.2, DRL marking, has been revised in the final rule 
to include the phrase ``* * * on its lens * * *'' after ``DRL'' to be 
faithful to the marking requirement as stated in paragraph 
S5.5.11(a)(2) of the current version of FMVSS No. 108.
    Several sections of the NPRM containing marking requirements for 
headlamps have been relocated in their entirety and without revision to 
paragraph S6.5.3 of the final rule. These include: (1) Proposed 
paragraph S17.1 which becomes S6.5.3.1; (2) S17.2 which becomes 
S6.5.3.2; (3) S17.3 which becomes S6.5.3.3 (split into several sections 
for clarity); and (4) S17.4 which becomes S6.5.3.4 (split for clarity 
and updated section references). Similarly, proposed paragraph S17.5 
summarizing the location of other headlamp marking requirements becomes 
paragraph S6.5.3.5.
    Proposed paragraph S6.6 stating requirements for associated 
equipment on regulated vehicles has been updated to indicate that the 
specific requirements for associated equipment are located in paragraph 
S9 of the final rule.
    Proposed paragraph S6.6.1, License plate holder, has been 
redesignated as paragraph S6.6.3 in the final rule due to renumbering 
of portions of paragraph S6.6 for clarity. AAM objected to this 
provision as stated previously in our discussion of SAE documents. The 
clarification that this section applied to rear license plate holders 
appears in the final rule (emphasis added).
    Paragraph 6.7, Replacement equipment, of the NPRM continues as that 
paragraph in the final rule. AAM, ASSN, and SEMA noted a typographic 
error in paragraph S6.7.1.2 where the word ``to'' inadvertently appears 
in the phrase ``* * * designed so that it does not to take the vehicle 
* * *'' (emphasis added). This error was corrected by removing that 
word from paragraph S6.7.1.2 of the final rule. SEMA commented that the 
language of paragraph S6.7 ``* * * infers that the standard would not 
preclude the installation of newer technologies on older vehicles and 
there is no suggestion that the introduction of lighting equipment into 
the marketplace is tied to vehicle manufacturer certification,''

[[Page 68247]]

and requested confirmation of this assumption by a response to its 
letter of December 16, 2005 requesting an interpretation by the Chief 
Counsel. SEMA's comment sought clarification of a notice of 
interpretation published in the Federal Register on November 1, 2005 
\20\ rather than addressing the substance of the rewrite of Standard 
No. 108, and, thus, was beyond the scope of the rewrite. We note that 
SEMA's concern was addressed by the agency in an August 24, 2006 letter 
of clarification.\21\

    \21\ http://isearch.nhtsa.gov/files/SEMA.htm_____________________________________-

    In its comments, ASSN objected to the inclusion of the second 
sentence of paragraph S6.7.1.2 of the NPRM which states in part, ``* * 
* the determination of whether a vehicle would be taken out of 
compliance with this standard when an individual device is installed on 
the vehicle is made without regard to whether additional devices, 
including separate lamps or reflective devices sold together with the 
device, would also be installed.'' Its contention is that this language 
which ``converts its informal interpretation into a formal rule'' was 
included in the rewrite of FMVSS No. 108 without ``the required cost 
benefit analysis'' and would limit the ``opportunities for vehicle 
personalization.'' The incorporation of the replacement equipment 
interpretation of 70 FR at 65972, or any interpretation, does not 
constitute a change in the requirements of the standard. An 
interpretation simply clarifies the existing requirements of the 
standard and as such does not require the cost-benefit analysis or 
other rulemaking formalities as ASSN suggested. Regulated parties are 
bound by the regulatory requirements regardless of whether they are 
expressed in the regulatory text or in interpretations either by letter 
or publication. A vehicle owner can continue to modify the lighting on 
his vehicle, including obtaining devices for that purpose from 
regulated parties such as vehicle dealers, so long as the vehicle 
continues to meet the requirements of FMVSS No. 108 and the replacement 
lighting equipment provides all regulated functions of the device being 
replaced in a single unit.
    Grote also commented on paragraph S6.7, requesting that the 
provisions of paragraph S6.7.1.2 not be applicable to heavy vehicles. 
Grote was concerned that a replacement lamp, reflective device, or item 
of associated equipment which is designed or recommended for particular 
vehicle models must be designed per S6.7.1.2 so that it does not take 
the vehicle out of compliance with this standard when the individual 
device is installed on the vehicle. Grote suggested that in the heavy 
vehicle market that it primarily serves, an owner of a fleet of heavy 
vehicles may elect to remove the original equipment lamps and 
reflective devices and replace them with equally compliant lamps and 
devices but in different functional combinations. That means, for 
example, one of a set of original equipment lamps installed on a 
particular vehicle may contain the stop lamp, taillamp, and side marker 
lamp function, while the other separate lamp contains the turn signal 
lamp, backup lamp, and reflex reflectors. Grote would like to be able 
to recommend a set of replacement lamps for this vehicle where the 
individual lamps of the set do not have the required functions grouped 
in exactly the same combinations as those of the original equipment 
set.
    Grote believes that it should be permissible to do this because the 
agency stated in the interpretation \22\ published in the Federal 
Register on November 1, 2005 that, ``* * * while our interpretation of 
S5.8.1 [of the current version of FMVSS No. 108] is not dependent on 
the size of the vehicle for which a lamp is intended, it has a more 
limited application to aftermarket lighting equipment for heavy 
vehicles than to light vehicles.'' However, the agency continued the 
discussion by stating, ``The specific context of the questions asked by 
Calcoast was aftermarket combination lamps for light vehicles, such as 
passenger cars. These lamps are typically designed for specific models 
and can only be installed on those models in the same location as the 
lamps they replace. However, for heavy vehicles, lighting equipment is 
often generic and not designed for specific models. Truck-Lite, for 
example, commented on our notice of draft interpretation that it sells 
many kinds of lighting devices through catalog sales to hundreds of 
vehicle manufacturers whose equipment it has no way of knowing about. 
Consistent with our discussion in the October 2004 notice of 
interpretation, we note that our interpretation does not mean that the 
manufacturer of generic lighting equipment has the responsibility for 
ensuring correct selection and installation of its equipment. On the 
other hand, under our interpretation, a manufacturer of aftermarket 
lighting equipment could not design or recommend lighting equipment for 
a specific vehicle if the vehicle manufacturer could not have certified 
the vehicle using that lighting equipment instead of the lighting 
equipment it actually used.'' We did not suggest in this interpretation 
that when we spoke of a ``more limited application'' in reference to 
heavy vehicles, we intended to treat replacement lamps and reflective 
devices for heavy vehicles significantly different than those for light 
vehicles. We were merely pointing out that we did not consider 
manufacturers of generic lighting equipment responsible for ensuring 
the correct selection and installation of their equipment. Therefore, 
with the exception of the previously mentioned typographical error 
correction, paragraph S6.7 in the final rule is identical to that of 
the NPRM.

---------------------------------------------------------------------------

    Proposed paragraph S6.8 of the NPRM has been relocated to be part 
of paragraph S14 of the final rule. Substantive issues raised in the 
public comments to the NPRM will be discussed in paragraph S14.
S7 Signal Lamp Requirements
    Paragraph S7 of the NPRM contained specific requirements for signal 
lamps, reflective devices, and associated equipment. With the 
reorganization of the final rule, only the signal lamp requirements 
remain in S7. In some cases, the order of appearance of specific lamp 
types in S7 has changed from the NPRM.
    As previously mentioned, we have partially adopted the request of 
ASSN/AAM concerning the format of individual lamp sections. We have 
modified the individual signal lamp sections so that a series of 
specific types of requirements are listed for each lamp in the same 
order in a ``template'' format. These requirements, in order, are: (1) 
Number, (2) Color of light, (3) Mounting location, (4) Mounting height, 
(5) Activation, (6) Markings, (7) Effective projected luminous lens 
area, (8) Visibility, (9) Indicator, (10) Spacing to other lamps, (11) 
Multiple compartment and multiple lamps, and (12) Ratio. These are 
followed by sections on Photometry and Physical tests. In many cases, 
the text following one of these types of requirements will ``point'' to 
a table or another section of the standard. Also, there are numerous 
instances where the specific lamp has no performance requirement for a 
category, and the text states ``No requirement.''
    References to physical tests applicable to signal lamps contained 
in Table XXII of the NPRM have been revised in the final rule to refer 
to paragraphs S14.4 and S14.5.

[[Page 68248]]

    Paragraph S7.1 of the final rule continues to contain the 
requirements for turn signal lamps. Paragraph S7.1.1.3 of the NPRM, 
addressing multiple compartment and multiple front turn signal lamps, 
becomes paragraph S7.1.1.11 in the final rule and has been split for 
clarity. In this section, Nissan stated that the term ``compartments'' 
after the word ``three'' was incorrectly plural; it has been changed to 
singular form in the final rule.
    As mentioned in the discussion of definitions, we replaced the term 
``functional lighted area'' in paragraph S7.1.1.2.2 of the NPRM 
(paragraph S7.1.1.10.3 in the final rule), with the equivalent term 
``effective projected luminous lens area.'' Since this paragraph was 
the only instance in Standard No. 108 where the term ``functional 
lighted area'' was used, it was eliminated from the definition of 
``Effective projected luminous lens area'' in the final rule.
    Calcoast objected to the language of paragraph S7.1.1.3.1 of the 
NPRM which stated, ``* * * overall width must meet the photometric 
requirements specified for a single section and not * * *'' photometric 
requirements for lamps installed on vehicles 2032 mm or more in overall 
width. In the final rule, we have changed this language in paragraph 
S7.1.1.11.4 to be faithful to the language of paragraph S5.1.1.12 of 
the current version of FMVSS No. 108. It now states, ``* * * overall 
width require measurement of the photometrics for the entire lamp and 
not.* * *'' This same issue was raised concerning rear turn signal 
lamps and stop lamps. Therefore, similar changes were made in paragraph 
S7.1.2.11.4 of the final rule for rear turn signal lamps and in 
paragraph S7.3.11.4 for stop lamps.
    Paragraph S7.1.1.3.2 of the NPRM (containing requirements for the 
ratio between the photometric intensity of a front turn signal lamp and 
that of a parking lamp or clearance lamp where optically combined) has 
become paragraph S7.1.1.12 in the final rule and has been split for 
clarity.
    Paragraph S7.1.2.2 of the NPRM (addressing multiple compartment and 
multiple rear turn signal lamps) becomes paragraph S7.1.2.11 in the 
final rule and has been split for clarity. Once again, Nissan stated 
that in this section, the term ``compartments'' after the word 
``three'' was incorrectly plural; it has been changed to singular form 
in the final rule.
    Paragraph S7.1.2.3 of the NPRM (containing requirements for the 
ratio between the photometric intensity of a rear turn signal lamp and 
that of a taillamp or clearance lamp where optically combined) becomes 
paragraph S7.1.2.12 in the final rule and has been split for clarity.
    Paragraph S7.2.1.1 of the NPRM (addressing multiple compartment and 
multiple taillamps) becomes paragraph S7.2.11 in the final rule and has 
been split for clarity. Again, Nissan stated that in this section the 
term ``compartments'' after the word ``three'' was incorrectly plural; 
it has been changed to singular form in the final rule. Also, AAM and 
Koito commented that there was an incorrect reference to Table VII 
instead of Table VIII in the NPRM; this has been corrected in the final 
rule.
    Paragraph S7.2.12, Ratio, has been added in the final rule to point 
to the ratio requirements for rear turn signal lamps and stop lamps 
optically combined with taillamps.
    Paragraph S7.3.1.1 of the NPRM (addressing multiple compartment and 
multiple stop lamps) becomes paragraph S7.3.11 in the final rule and 
has been split for clarity. Again, Nissan stated that in this section 
the term ``compartments'' after the word ``three'' was incorrectly 
plural; it has been changed to singular form in the final rule.
    Paragraph S7.3.1.2 of the NPRM (containing requirements for the 
ratio between the photometric intensity of a stop lamp and that of a 
taillamp where optically combined) becomes paragraph S7.3.12 in the 
final rule and has been split for clarity.
    Koito commented about the limitation of the application of reduced 
photometry requirements of paragraph S7.4.1.1 of the NPRM to side 
marker lamps installed on vehicles less than 80 inches wide. This 
limitation is consistent with Table 1, footnote ``b'' of SAE J592e. A 
more comprehensive discussion of this issue is part of the section on 
SAE documents in this final rule.
    Paragraph S7.5.12, Ratio, has been added in the final rule to point 
to the ratio requirements for front and rear turn signal lamps 
optically combined with clearance lamps.
    Paragraphs S7.7.2, Photometry, and S7.7.1, Installation, of the 
NPRM (applicable to license plate lamps) have been split for clarity as 
paragraphs S7.7.13 and S7.7.15 respectively, in the final rule.
    A reference to new Figure 20, License Plate Lamp Measurement of 
Incident Light Angle, was added to paragraph S7.7.15.4 of the final 
rule (paragraph S7.7.1.1 in the NPRM.)
    Paragraphs S7.9.1, Accessibility, and S7.9.2, Installation, of the 
NPRM (applicable to high-mounted stop lamps) were relocated in the 
final rule to be paragraphs S6.1.3.4.2 and S6.1.3.4.1, respectively.
    Guide commented that paragraph S7.11.2.2(c) of the NPRM should be 
relocated to the DRL activation portion of Table I-a. We disagree. This 
requirement, which becomes paragraph S7.10.10.1(c) in the final rule, 
only specifies activation and deactivation of the DRL when the turn 
signal is activated on a vehicle where the DRL is in close proximity to 
a turn signal lamp. Given these constraints of limited application, its 
present placement in the final rule is the most appropriate location. A 
statement in the DRL activation portion of Table I-a does point to 
paragraph S7.10.10.1(c) to also alert users to this requirement.
S8 Reflective Device Requirements
    Requirements for reflex reflectors located in paragraph S7.10 of 
the NPRM have been relocated to paragraph S8.1 in the final rule. 
Paragraphs S8.1.1 through S8.1.10 are categorized identically to the 
organizational template of signal lamps. However, a section covering 
multiple compartment lamp and multiple lamps and a section covering 
ratio are clearly not applicable to reflex reflectors and are not 
included. Paragraph S8.1.11, Photometry, replaces paragraph S7.10.1 of 
the NPRM, while paragraph S8.1.12, Physical tests, replaces paragraph 
S7.10.2 and paragraph S8.1.13, Alternative reflex material, replaces 
paragraph S7.10.1.1.
    References to physical tests applicable to reflex reflectors 
contained in Table XXII of the NPRM have been revised in the final rule 
to refer to paragraphs S14.4 and S14.5.
    The final rule combines the content of paragraph S7.12 and Table 
III of the NPRM into paragraph S8.2. Specifically, proposed paragraph 
S7.12 becomes paragraph S8.2, proposed paragraph S7.12.1 becomes 
paragraph S8.2.1, Retroreflective sheeting, (split for clarity), and 
proposed paragraph S7.12.1.1 becomes paragraph S8.2.1.3, Certification 
marking.
    Following this, the text of the proposed Application pattern-
Alternating red and white materials-Retroreflective sheeting box of 
Table III is stated as paragraph S8.2.1.4, the text of the proposed 
Application location-Retroreflective sheeting box of Table III is 
stated as paragraph S8.2.1.5, and the text of the proposed Application 
spacing-Retroreflective sheeting box of Table III is stated as 
paragraph S8.2.1.6.
    3M commented that they believe that the use of the phrase ``* * * 
material is required to be installed * * *'' in both

[[Page 68249]]

the requirements for Application pattern-Retroreflective sheeting and 
Application pattern-Conspicuity reflex reflectors implies that there is 
only one method of meeting conspicuity requirements, not two 
alternative methods. To increase clarity of these alternative 
requirements, we have revised the first sentence of the Alternating red 
and white materials-Retroreflective sheeting, (now paragraph 
S8.2.1.4.1) requirement to read ``* * * where alternating material is 
installed * * *'' We have also eliminated the phrase ``Where 
alternating color material is required to be installed'' from the 
beginning of the first sentence of Alternating red and white materials-
Conspicuity reflex reflectors section (now paragraph S8.2.2.2.1).
    3M also commented that the language in the Application pattern-
White material-Conspicuity reflex reflectors section (paragraph 
S8.2.2.2.2 of the final rule) discussing the dimensional relationship 
between adjacent white conspicuity reflex reflectors would be more 
appropriately included in the Application location portion. We disagree 
because the requirements in the Application location portion refer to 
the location of the material on the vehicle while the requirements in 
the Application pattern portion only refer to the location of a 
reflector to an adjacent reflector.
    AAM commented that the language of the Application location-
Retroreflective sheeting portion begins with the phrase ``Not permitted 
* * *'' which imposes a different requirement than paragraph S5.7.1.4 
of the current version of FMVSS No. 108 which states ``* * * but need 
not be applied * * *'' We agree and have revised the requirement of the 
Application location-Retroreflective sheeting (now paragraph S8.2.1.5 
in the final rule) to begin, ``Need not be installed, as illustrated in 
Figure 12-2, * * *''
    Proposed paragraph S7.12.1.2, Photometry, becomes paragraph 
S8.2.1.7 in the final rule with no substantive changes. The photometry 
requirements reference was updated to Table XVI-c and the photometry 
test procedure reference to paragraph S14.2.3.
    Proposed paragraph S7.12.2, Conspicuity reflex reflectors, becomes 
paragraph S8.2.2 and proposed paragraph S7.12.1, Certification marking, 
becomes paragraph S8.2.2.1 in the final rule.
    Following this, the text of the proposed Application pattern-
Alternating red and white material-Conspicuity reflex reflectors box of 
Table III is stated as paragraph S8.2.2.2.1 and the proposed 
Application pattern-White material-Conspicuity reflex reflectors box of 
Table III is stated as paragraph S8.2.2.2.2. Regarding retroreflective 
sheeting, we have addressed the previously noted 3M comment about 
alternative methods of meeting conspicuity requirements by eliminating 
the phrase ``Where white material is required to be installed'' from 
the beginning of the first sentence of the Application pattern-White 
material-Conspicuity reflex reflectors (now paragraph S8.2.2.2.2) 
section.
    Proposed paragraph S7.12.2.2, Photometry, has become paragraph 
S8.2.2.3 (split for clarity) in the final rule.
    Paragraph S8.2.3 of the final rule contains the requirements for 
conspicuity systems installed on trailers that were part of Table III 
in the NPRM. Paragraph S8.2.3.1 (split for clarity) includes the 
requirements for the three conspicuity elements required on the rear of 
a trailer and paragraph S8.2.3.2 (split for clarity) states 
requirements for the alternating color side conspicuity treatment 
required on trailers.
    AAM requested that the specific grades of sheeting permitted be 
mentioned in the requirements for Trailer rear-Element 2-white, now in 
paragraph S8.2.3.1.2.1. Therefore, we have inserted the phrase ``* * * 
of Grade DOT-C2, DOT-C3, or DOT-C4 * * *'' between the word ``long'' 
and the word ``applied'' in the first sentence making the language of 
the requirement faithful to that of paragraph S5.7.1.4.1(b) of the 
current version of FMVSS No. 108.
    TTMA commented that certain tank trailers may not have a vertical 
surface suitable for installing the Trailer side-alternating red and 
white materials conspicuity material between 375 mm and 1525 mm above 
the road surface. If installed in a downward orientation, it would not 
be effective for its purpose. The requirement of this section states 
that the material must be installed in this height range if practicable 
and going beyond this range is permitted if it aids correct 
orientation. We believe that the language of paragraph S8.2.3.2.1 of 
the final rule, along with the illustrative examples of conspicuity 
treatment applied to tank trailers shown in Figure 11, adequately 
addresses this issue.
    Paragraph S8.2.4 of the final rule contains the requirements for 
conspicuity systems installed on truck tractors, which was part of 
Table III in the NPRM. Paragraph S8.2.4.1 (split for clarity) contains 
requirements for Element 1 (alternating color) and paragraph S8.2.4.2 
(split for clarity) states the requirements for Element 2 (white). One 
mounting alternative for conspicuity treatment requirements in Truck 
tractor-Element 1 was inadvertently omitted from the NPRM. This 
material is allowed to be mounted to ``plates attached to the mudflap 
support brackets'' as stated in the current version of FMVSS No. 108 at 
paragraph S5.7.1.4.3(a). We have inserted this alternative mounting 
location after ``mudflap support brackets'' and before ``or on the 
mudflaps'' in paragraph S8.2.4.1.1 of the final rule.
S9 Associated Equipment Requirements
    Section 7.14 of the NPRM, Associated equipment requirements, is 
relocated to paragraph S9 in the final rule.
    Koito and Nissan commented that the first sentence of paragraph 
S7.14.1 of the NPRM, now paragraph S9.1.1 of the final rule, virtually 
duplicated the definition of Turn signal operating unit in S4. We agree 
and removed that sentence from paragraph S9.1.1. Paragraph S9.1.2 of 
the final rule states that turn signal operating units must meet the 
applicable performance requirements of paragraph S14.9. These 
references are to paragraph S6.6 and Table XXI in the NPRM.
    Similarly, the first sentence of paragraph S7.14.2 of the NPRM, now 
paragraph S9.2.1 of the final rule, virtually duplicated the definition 
of Turn signal flasher in S4. We removed that sentence from paragraph 
S9.2.1. Paragraph S9.2.2 of the final rule states that turn signal 
flashers must meet the applicable performance requirements of paragraph 
S14.9. These references are to paragraph S6.6 and Table XXI in the 
NPRM.
    In the NPRM, paragraph S7.14.3 stated requirements for the turn 
signal pilot indicator. These requirements have been relocated to 
paragraph S9.3 (split for clarity) in the final rule. Paragraph 
S7.14.3.1 of the NPRM described the turn signal pilot indicator size 
and color requirements. These requirements were erroneously based on 
paragraph 5.4.3 of SAE J588 NOV84, Turn Signal Lamps for use on Motor 
Vehicles less than 2032 mm in Overall Width. These requirements should 
have been based upon paragraph 4.5 of SAE J588e, Turn Signal Lamps, 
September 1970, as specified by paragraph S5.5.6 of the current version 
of FMVSS No. 108. We have stated the correct requirements in paragraph 
S9.3.4 of the final rule. These corrected requirements include a 
visibility requirement that references SAE J941b, Motor Vehicle 
Driver's Eye Range, February 1969, rather than the incorrect reference 
to SAE J1050,

[[Page 68250]]

Describing and Measuring the Driver's Field of View, which was included 
in the NPRM.
    The incorporation in paragraph S7.14.3.2 of the NPRM of the 
language from the incorrect version of SAE J588 also caused the 
description of the modes of indication of the turn signal pilot 
indicator to be omitted as noted in the comments from AAM. We have 
corrected this in the final rule by inserting the phrase ``* * *by a 
``steady on'', ``steady off'', or by a significant change in the 
flashing rate* * *'' into the text of paragraph S9.3.6.
    We also neglected in the NPRM to cite the reason for our use of the 
failure indication criteria of ``* * *minimum photometric performance 
specified in Tables VI or VII* * *'' rather than the text of paragraph 
S5.5.6 of the current version of FMVSS No. 108, which states that 
criteria as ``Failure of one or more turn signal lamps to operate* * 
*.'' The language incorporated in the NPRM came from the July 10, 1998 
letter of interpretation to Mr. Binder.\23\ In that interpretation, the 
issue of how to indicate to the driver the failure of a turn signal 
lamp that consisted of a number of LED light sources was discussed. The 
failure indication criteria for this situation was stated in Binder in 
this way, ``If a light source fails in a turn signal lamp on a vehicle 
that is not equipped to tow a trailer, Standard No. 108 requires that 
the failure be indicated to the driver. We are not aware of any LED 
turn signals in use, or how manufacturers would design such a unit to 
comply with this requirement. However, we believe that a failure should 
be indicated to the driver at the point where an LED turn signal ceases 
to furnish the minimum photometric performance required by Standard No. 
108.'' The statements in the Binder interpretation also apply to turn 
signal lamps using conventional incandescent light sources. If a turn 
signal lamp using an incandescent light source fails, it obviously has 
zero photometric output. Therefore, we adopted the language of Binder 
in the NPRM but omitted mention of it as one of the incorporated 
interpretations. We are correcting that omission here and are 
preserving the failure indication criteria of the NPRM in paragraph 
S9.3.6 of the final rule.

    Paragraphs S7.14.4, Headlamp beam switching device, and S7.14.4.1, 
Semi-automatic headlamp beam switching device, of the NPRM, were re-
designated as paragraphs S9.4 and S9.4.1, respectively, in the final 
rule. Paragraph S9.4.1.4 of the final rule, which was paragraph 
S7.14.4.1.4 in the NPRM, had a second sentence added to it which 
states, ``The device shall not affect the function of the upper beam 
indicator light.'' which was inadvertently omitted from the NPRM. This 
requirement comes from paragraph 4.14 of SAE J565b, Semiautomatic 
Headlamp Beam Switching Devices, February 1969, which is incorporated 
by reference in the current version of FMVSS No. 108.
    Paragraph S9.4.1.7 of the final rule states that semi-automatic 
headlamp beam switching devices must be designed to conform to the 
performance requirements of paragraph S14.9. These references are to 
paragraph S6.6 and Table XXI in the NPRM.
    Paragraphs S7.14.5 Upper beam headlamp indicator, and S7.14.5.1 
Indicator size, location, and color, of the NPRM, become paragraphs 
S9.5 and S9.5.1, respectively, in the final rule. However, the term 
``color'' and the last sentence of paragraph S7.14.5.1 stating that the 
color of the indicator need not be red were deleted from paragraph 
S9.5.1. By removing this language and making Standard No. 108 silent 
about the color of the upper beam headlamp indicator, we have 
simplified the manner in which the requirement is presented. The 
current version of FMVSS No. 108 states in paragraph S5.5.2 that, 
``Each vehicle shall have a means for indicating to the driver when the 
upper beams of the headlamps are on that conforms to SAE Recommended 
Practice J564a, April 1964, except that the signal color need not be 
red''. The second paragraph of SAE J564a states that ``* * *The upper 
beam indicator should consist of a red light* * *.'' As noted in the 
comments of AAM, we incorporated in the NPRM the requirements of SAE 
J564a directly into the text of the Standard No. 108 without including 
the red color requirement because of the noted exclusion. However, we 
neglected to remove the excluding language from the NPRM. We are doing 
so in the final rule.
    Koito and Nissan commented that the first sentence of paragraph 
S7.14.6 of the NPRM, now paragraph S9.6.1 of the final rule, virtually 
duplicated the definition of Vehicular hazard warning signal operating 
unit in S4. We agree and removed that sentence from paragraph S9.6.1. 
Paragraph S9.6.3 of the final rule states that vehicular hazard warning 
signal operating units must meet the applicable performance 
requirements of paragraph S14.9. These references are to paragraph S6.6 
and Table XXI in the NPRM.
    Similarly, the first sentence of paragraph S7.14.7 of the NPRM, now 
paragraph S9.7.1 of the final rule, virtually duplicated the definition 
of Vehicular hazard warning signal flasher in S4. We removed that 
sentence from paragraph S9.7.1. Paragraph S9.7.2 of the final rule 
states that vehicular hazard warning signal flashers must meet the 
applicable performance requirements of paragraph S14.9. These 
references are to paragraph S6.6 and Table XXI in the NPRM.
    Requirements for the vehicular hazard warning signal pilot 
indicator from paragraph S7.14.8 of the NPRM are relocated intact to 
paragraph S9.8 (split for clarity) in the final rule. AAM commented 
that a vehicular hazard warning signal pilot indicator was not required 
by FMVSS No. 108. We direct AAM's attention to SAE J910, Vehicular 
Hazard Warning Signal Operating Unit, January 1966, specifically 
paragraph 5. When we removed J910 as a referenced document in the NPRM, 
we incorporated the requirements of paragraph 5 into paragraph S7.14.8, 
which we are now designating as paragraph S9.8 in the final rule. \24\
---------------------------------------------------------------------------

    \24\ SAE J945, Vehicular Hazard Warning Signal Flasher, February 
1966 incorporated by reference in the current version of FMVSS No. 
108 also discusses a visible pilot indicator for the vehicular 
hazard warning signal. The test condition requirement of S9.8.3 of 
the final rule comes from J945.
---------------------------------------------------------------------------

S10 Headlighting System Requirements.
    The headlighting system requirements of S8 of the NPRM become S10 
of the final rule.
    Paragraph S8.1 of the NPRM is now paragraph S10.1 (split for 
clarity) in the final rule. Guide commented that paragraphs S8.1.1 and 
S8.1.2 of the NPRM were redundant with the requirement, of paragraph 
S8.1, that the headlighting system conforms to one of the systems of 
Table II. We agree and eliminated paragraphs S8.1.1 and S8.1.2 from the 
final rule.
    We mentioned previously in the discussion of mounting location 
requirements that Guide commented that the content of sections 8.1.3 
and 8.1.4 of the NPRM, dealing with headlamp beam mounting, was most 
appropriately located in the lamp mounting location section. We agree 
and have moved them intact to become paragraph S6.1.3.5 of the final 
rule.
    Paragraph S8.1.5, Headlamp adjustments, of the NPRM was relocated 
to be paragraphs S10.18.1.1 and S10.18.1.2 of the final rule.
    We adopted, in S10 of the final rule, the ASSN/AAM suggested 
standard format similar to that of the signal lamp and reflex reflector 
sections. Those standardized criteria that apply to headlamps with the 
appropriate

[[Page 68251]]

pointing statements or ``no requirement'' notations become paragraphs 
S10.3 through S10.12 of the final rule.
    The requirements for a sealed beam headlighting system, which were 
S9 of the NPRM, become paragraph S10.13 in the final rule. Paragraphs 
S9 and S9.1 of the NPRM have been relocated intact to become paragraphs 
S10.13 and S10.13.1 respectively in the final rule. The simultaneous 
aim requirements for type ``F'' sealed beam headlamps, which were 
paragraph S9.2 in the NPRM, become S10.13.2 in the final rule, the only 
revision being the revised reference for the applicable photometry 
procedure. Paragraph S9.3, Photometry, of the NPRM becomes paragraph 
S10.13.3 in the final rule, again with a revised reference to the 
photometry procedure. The physical tests requirements of paragraph S9.4 
of the NPRM, which referenced Tables XXII and XXIII, become paragraph 
S10.13.4 (split for clarity) in the final rule, with updated references 
to the applicable test procedures and performance requirements in 
paragraph S14.
    The requirements for an integral beam headlighting system that were 
paragraph S10 of the NPRM become paragraph S10.14 in the final rule. 
Paragraphs S10 and S10.1 of the NPRM have been relocated to be 
paragraphs S10.14 and S10.14.1, respectively, in the final rule, with 
the only revision being the substitution of the term ``activated'' for 
the term ``mechanized'' used in the NPRM. Paragraphs S10.2, S10.3, and 
S10.4 of the NPRM have been relocated to become paragraphs S10.14.2 
(split for clarity), S10.14.3, and S10.14.4 respectively in the final 
rule.
    AAM and Koito both commented that the language in paragraph S10.5 
(repeated in paragraph S11.3) of the NPRM, stating that, ``An integral 
beam (replaceable bulb in paragraph S11.3) headlamp may incorporate 
replaceable light sources that are used for purposes other than 
headlighting'', could be interpreted to mean those ``replaceable light 
sources'' defined in S4 of the NPRM. This language came from paragraphs 
S7.4(i) and S7.5(j) of the current version of Standard No. 108. To 
alleviate concerns that this incorrect interpretation could be applied, 
we have revised the language of paragraph S10.5 (and paragraph S11.3) 
of the NPRM. Paragraph S10.14.5 (and paragraph S10.15.5) of the final 
rule now states, ``An integral beam (replaceable bulb in paragraph 
S10.15.5) headlamp may incorporate light sources that are used for 
purposes other than headlighting and are capable of being replaced.''
    Paragraph S10.6, Photometry, of the NPRM becomes paragraph S10.14.6 
in the final rule, with a revised reference to the photometry 
procedure. The physical test requirements of paragraph S10.7 of the 
NPRM, which referenced Table XXII and Table XXIII, become paragraph 
S10.14.7 (split for clarity) in the final rule, with updated references 
to the applicable test procedures and performance requirements in 
paragraph S14.
    The requirements for a replaceable bulb headlighting system, which 
were paragraph S11 of the NPRM, become paragraph S10.15 in the final 
rule. Paragraph S11 of the NPRM has been relocated intact to be 
paragraph S10.15 in the final rule. Koito commented that the language 
of paragraph S11.1 of the NPRM stating, ``* * *must consist of the 
correct number of designated headlamp units shown for* * *'' did not 
clearly express the requirement. We agree and have revised this phrase 
to, ``* * *must consist of either two or four headlamps shown for* * 
*'' in paragraph S10.15.1 of the final rule.
    Paragraph S11.2 of the NPRM becomes paragraph S10.15.2 in the final 
rule. Paragraph S11.4 of the NPRM has the phrase ``* * *be designed to* 
* *'' inserted before the word ``conform'' when it becomes paragraph 
S10.15.3 of the final rule.
    Paragraph S11.5 of the NPRM is relocated to become paragraph 
S10.14.4.1 of the final rule. It is supplemented by a new paragraph 
S10.15.4.2 stating the exception from the requirements of paragraph 
S10.14.4.1 (that were contained in paragraphs S7.5(d)(3)(i)(A) and 
S7.5(d)(3)(ii)(A) of the current version of FMVSS No. 108), which was 
omitted from the NPRM, as noted in the comments of Guide and Koito.
    As previously mentioned, paragraph S11.3 of the NPRM was revised 
for clarity and becomes paragraph S10.15.5 in the final rule.
    Paragraph S11.6, Photometry, of the NPRM becomes paragraph S10.15.6 
in the final rule, with a revised reference to the photometry 
procedure. The physical tests requirement of paragraph S11.7 of the 
NPRM, which referenced Table XXII and Table XXIII, becomes paragraph 
S10.15.7 (split for clarity) in the final rule, with updated references 
to the applicable test procedures and performance requirements in 
paragraph S14.
    The requirements for a combination headlighting system that were 
S12 of the NPRM become paragraph S10.16 in the final rule. Paragraphs 
S12 and S12.1 of the NPRM have been relocated to be paragraphs S10.16 
and S10.16.1, respectively, in the final rule, with the only revision 
being the substitution of the term ``activated'' for the term 
``mechanized'' used in the NPRM.
    Paragraph S12.2, Photometry, of the NPRM becomes paragraph S10.16.2 
in the final rule, with a revised reference to the photometry 
procedure. The physical test requirements of paragraph S12.3 of the 
NPRM, which referenced Table XXII and Table XXIII, become paragraph 
S10.16.3 (split for clarity) in the final rule, with updated references 
to the applicable test procedures and performance requirements in 
paragraph S14.
    The requirements for a motorcycle headlighting system that were S13 
of the NPRM become paragraph S10.17 in the final rule. Paragraphs 
S13.1, S13.1.1 (split for clarity), S13.1.2 (split for clarity), and 
S13.1.3 (split for clarity) of the NPRM are relocated intact to become 
paragraphs S10.17.1, S10.17.1.1, S10.17.1.2, and S10.17.1.3, 
respectively, of the final rule. Paragraph S13.4 of the NPRM becomes 
paragraph S10.17.2 of the final rule.
    Paragraph S13.2, Photometry, of the NPRM becomes paragraph S10.17.3 
in the final rule, with a revised reference to the photometry 
procedure. The physical test requirements of paragraph S13.3 of the 
NPRM, which referenced Table XXII, become paragraph S10.17.5 in the 
final rule, with updated references to the applicable test procedures 
and performance requirements in paragraph S14.
    Paragraphs S13.5.1, Modulation, S13.5.2, Replacement modulators, 
S13.5.2.1, Replacement performance, and S13.5.2.2, Replacement 
instructions, of the NPRM are relocated intact to become paragraphs 
S10.17.5.1, S10.17.5.2, S10.17.5.2.1, and S10.17.5.2.2, respectively, 
in the final rule.
    Headlamp aimability requirements that were located in S14 in the 
NPRM have been relocated to paragraph S10.18 in the final rule with one 
exception and with very few revisions. The exception is proposed 
paragraph S14.2 dealing with equipment in front of a headlamp lens. The 
requirements of this section were moved to paragraph S6.2.6 in the 
Impairment section of the final rule.
    Paragraph S14.8.2 of the NPRM, which becomes paragraph S10.18.7.2 
of the final rule, contains requirements for use of nonadjustable 
headlamp aiming device locating plates for five types of sealed beam 
headlamps. The language in the NPRM stated that these units should 
incorporate lens-mounted aiming pads specified in Figures a, b, c, d, 
or e of the NPRM. The figures referred to were intended to be 
placeholders in

[[Page 68252]]

a draft version of the NPRM. The NPRM should have stated that, ``* * * 
incorporate lens-mounted aiming pads as specified for those units in 
Appendix C of part 564 of this chapter,'' which is incorporated in 
paragraph S10.18.7.2 of the final rule.
    Koito requested that an alternative measurement distance of 25 m be 
permitted for the measurement of the cutoff parameter for a visually/
optically aimed headlamp. Paragraph S14.10.1.5 of the NPRM, based upon 
the April 6, 2000 letter of interpretation to Mr. Spingler,\25\ 
required the measurement distance to be 10 m. One of the objectives of 
the rewrite of Standard No. 108 is to improve the clarity of the 
document without changing the substance of the existing requirements. 
The referenced letter of interpretation states a specific measurement 
distance without alternatives. Therefore, Koito's request would be a 
substantive change beyond the scope of the rewrite and paragraph 
S10.18.9.1.5 of the final rule duplicates the requirement from the 
NPRM.

S11 Replaceable Light Source Requirements
    Paragraph S15 of the NPRM, Replaceable light source requirements, 
is relocated to S11 in the final rule. Paragraphs S15 and S15.1 from 
the NPRM become paragraphs S11 and S11.1, respectively, in the final 
rule. Paragraph S15.4, Ballast markings, of the NPRM becomes paragraph 
S11.2 in the final rule and paragraph S15.5, Gas discharge laboratory 
life, becomes paragraph S11.3. Paragraph S15.6 of the NPRM, containing 
requirements for physical tests of replaceable light sources, is split 
into paragraphs S11.4.1 and S11.4.2 in the final rule. Paragraph 
S11.4.1 references the deflection test and pressure test applicable to 
replaceable light sources, which were part of Table XXIII in the NPRM 
and have been relocated to paragraph S14.7 in the final rule. Paragraph 
S11.4.2 references a restated power and flux measurement test that is 
described in paragraph S14.7.3 of the final rule, noting that the 
performance requirements for this test do not reside in the main text 
of Standard No. 108, but in the applicable appendix of part 564 of this 
chapter.
    The NPRM contained paragraphs S15.2 and S15.3, both titled Power 
and flux measurement, which essentially described the same test of 
replaceable light sources. Recognizing that they were test procedures 
and striving to advance the objectives of the rewrite, we consolidated 
the procedures of paragraphs S15.2 and 15.3 into a single procedure, 
without revising or modifying the requirements, and relocated it to 
paragraph S14.7.3 of the final rule.
S12 Headlamp Concealment Device Requirements
    The headlamp concealment device requirements of S16 of the NPRM are 
relocated intact to S12 of the final rule.
S13 Replaceable Headlamp Lens Requirements
    The replaceable headlamp lens requirements of paragraph S18 of the 
NPRM are relocated intact (split for clarity) to paragraph S13 of the 
final rule.
S14 Physical and Photometry Test Procedures and Performance 
Requirements
    As previously mentioned, ASSN/AAM and Grote commented that tables 
containing significant amounts of text, such as the test requirements 
in Tables XXI, XXII, and XXIII of the NPRM, are difficult to use 
because of lengthy passages that contain several sentences and express 
several unique test conditions or requirements. We agree with these 
comments. In the final rule, we have moved virtually all test 
procedures and their associated performance requirements to S14.
    General test procedures and performance requirements that were 
located in paragraph S6.8 of the NPRM have been placed in paragraph 
S14.1 of the final rule. Similarly, the photometric test procedures of 
paragraph S6.8 of the NPRM are now paragraph S14.2 of the final rule.
    Part of Table XXII of the NPRM, the out of focus test applicable to 
motorcycle headlamps designed to conform to paragraph S10.17(b), 
becomes paragraph S14.3 in the final rule. The color test and plastic 
optical materials test of Table XXII become paragraph S14.4 in the 
final rule. The remaining tests of Table XXII, the vibration test, 
moisture test, dust test, and corrosion test, become paragraph S14.5 in 
the final rule.
    All tests applicable to complete headlamps included in Table XXIII 
of the NPRM have been relocated to paragraph S14.6 of the final rule. 
The tests in Table XXIII of the NPRM related to replaceable light 
sources become paragraph S14.7 in the final rule. Tests in Table XXIII 
of the NPRM that apply to vehicle headlamp aiming devices (VHAD) were 
relocated to be paragraph S14.8 in the final rule. Also, the tests 
applicable to associated equipment that were located in Table XXI of 
the NPRM become paragraph S14.9 in the final rule.
    S6.8.1 of the NPRM, stating that lamps, reflective devices, and 
associated equipment regulated by Standard No. 108 be designed to 
conform to applicable physical test requirements, becomes paragraph 
S14.1.1 of the final rule. This is followed by proposed paragraphs 
S6.8.4 and S.8.4.1 of the NPRM, applicable to plastic optical 
materials, which become paragraphs S14.1.2 and S14.1.3, respectively, 
in the final rule. Bayer had asked that the word ``reflex'' be placed 
before the word ``reflector'' in paragraph S14.1.2 but we prefer to 
keep the language faithful to paragraph S5.1.2 of the current version 
of Standard No. 108. Paragraph S14.1.4, Samples, of the final rule is 
paragraph S6.8.2 (split for clarity) of the NPRM, except for the 
sentence ``A mounting bracket with a sample headlamp installed must not 
have a resonant frequency in the 10-55 Hz. range'' which was relocated 
to paragraph S14.6.8.1 in the final rule because of its specific 
applicability to the vibration test for headlamps. Paragraph S6.8.3 of 
the NPRM is now paragraph S14.1.5 of the final rule.
    Paragraph S6.8.5 of the NPRM becomes paragraph S14.2, Photometric 
test procedures, in the final rule. Paragraph S6.8.5.1 was split for 
clarity and becomes paragraph S14.2.1 in the final rule. Nissan 
commented that the measurement distance requirements in paragraph 
S6.8.5.1 were confusing because they mentioned license plate lamps and 
headlamps. We agree and have revised the text of paragraph S14.2.1.3 of 
the final rule to expressly state the required distance for all lamps 
that paragraph S14.2.1 applies to. Nissan also noted that proposed 
paragraph S6.8.5.1 contained a requirement for photometric intensity 
between test points that was duplicated in several photometry 
requirements tables as a footnote. We eliminated this language from 
paragraph S14.2.1 of the final rule, deciding that the individual 
requirements tables were the appropriate location for the intensity 
between test point requirements.
    Paragraph S6.8.5.1.1 of the NPRM becomes, in its entirety, 
paragraph S14.2.1.4 (split for clarity) of the final rule. Paragraph 
S6.8.5.1.2, detailing requirements for photometry of multiple 
compartment lamps and multiple lamps, becomes paragraph S14.2.1.5 in 
the final rule. We adopted the suggestion of Koito to specifically 
indicate the type of lamps to which this section applies.

[[Page 68253]]

    Paragraph S6.8.5.2 of the NPRM becomes paragraph S14.2.1.6 (split 
for clarity) in the final rule. Paragraph S14.2.1.6.2 was added to this 
section at the suggestion of Calcoast, which observed that the NPRM had 
not included the content of Footnotes 2 and 3, which follow Table IV, 
of the current version of FMVSS No. 108. The last sentence of paragraph 
S6.8.2, which specifically addressed samples for the color test of 
reflex reflectors, was moved to be paragraph S14.4.1.1 of the final 
rule.
    Paragraph S6.8.5.3, License plate lamp photometry, of the NPRM 
becomes paragraph S14.2.2 in the final rule. Paragraphs S6.8.5.3.1 and 
S6.8.5.3.2 of the NPRM become paragraphs S14.2.2.1 and S14.2.2.2, 
respectively, in the final rule. Nissan observed that the language of 
paragraph S6.8.5.3.2 was awkward and suggested a revision that did not 
change the substance of the requirement. We adopted Nissan's suggestion 
in paragraph S14.2.2.2. We also added paragraph S14.2.2.3 to the final 
rule to clarify that the bulb requirements of paragraph S14.2.1.6 also 
apply to license plate lamp photometry.
    Proposed paragraph S6.8.5.4, stating requirements for reflex 
reflector and retroreflective sheeting photometry, becomes paragraph 
S14.2.3 in the final rule. For clarity, paragraph S6.8.5.4 of the NPRM 
has been split into paragraphs S14.2.3.1 through S14.2.3.6 and 
paragraph S6.8.5.4.1 has been split into paragraphs S14.2.3.7.1 through 
S14.2.3.8.2 in the final rule. Likewise, paragraph S6.8.5.4.1.1 in the 
NPRM becomes paragraph S14.2.3.8.3.1 in the final rule.
    3M commented that the language of paragraph S6.8.5.4.1 of the NPRM, 
which is paragraph S14.2.3.7 of the final rule, did not allow a 
complete photometric evaluation of retroreflective sheeting because a 
presentation angle was not specified. 3M's premise was that the test 
method of the current version of FMVSS No. 108 relies on conventions 
regarding orientation and presentation that are part of ASTM E 810, 
Standard Test Method for Coefficient of Retroreflection of 
Retroreflective Sheeting Utilizing the Coplaner Geometry, which is 
referenced by ASTM D 4956, Standard Specification for Retroreflective 
Sheeting for Traffic Control, a document 3M contends is no longer 
referenced in the NPRM. This contention is incorrect. The reference to 
ASTM D 4956, from paragraph S5.7.1.2 of the current version of FMVSS 
No. 108, is replicated in paragraph S7.12.1 of the NPRM and finally by 
paragraph S8.2.1.2 of the final rule, with consistent language 
throughout. Since the connection to ASTM E 810 still exists, we see no 
reason to modify the final rule as 3M suggested.
    Nissan suggested that the language concerning the mounting of a 
reflex test sample for photometry, which becomes paragraph S14.2.3.1 of 
the final rule, did not allow for a test chamber which does not provide 
a linear 100 foot test distance, but rather was arranged in a non-
horizontal orientation. We do not agree and, therefore, have not 
changed the text from the NPRM to the final rule. The procedure of 
paragraph S14.2.3.1 is faithful to the language of paragraph 3.1.7 of 
SAE J594f, Reflex Reflectors, January 1977, incorporated by reference 
in the current version of FMVSS 108.
    The reflex reflector photometry test, like all tests in Standard 
No. 108, describes a procedure that NHTSA would use to test a reflex 
reflector for purposes of compliance. It also describes the performance 
requirements that the reflector must be designed to conform to, when 
tested according to the procedure. If a manufacturer chooses to use a 
procedure that differs with that described in FMVSS No. 108 as its 
basis of compliance, or to establish a basis of compliance that does 
not rely on an actual test, it is free to do so. However, the 
manufacturer must exercise due care in designing its product to conform 
to the performance requirements of all applicable tests in Standard No. 
108 when tested according to the procedures stated in the standard.
    Paragraph S6.8.5.5, Daytime running lamp (DRL) photometry 
measurements, of the NPRM becomes paragraph S14.2.4 (split for clarity) 
of the final rule. Paragraph S14.2.4.3 was added to the final rule to 
clarify that the bulb requirements of paragraph S14.2.1.6 also apply to 
DRL photometry.
    Nissan expressed some confusion regarding how a dedicated DRL, 
without any equipment that alters or conditions the voltage, should 
have power applied to it for photometric testing as stated in paragraph 
S14.2.4. We are unable to answer this question as part of the rewrite 
process and note Nissan can request an interpretation for this specific 
situation.
    Paragraph S6.8.5.6 of the NPRM, covering photometry measurements of 
headlamps, becomes paragraph S14.2.5 in the final rule. Some 
rearrangement of content and splitting of sections for clarity was 
incorporated into the final rule. Specifically, paragraph S14.2.5.1 of 
the final rule contains the first sentence of paragraph S6.8.5.6 of the 
NPRM, paragraph S14.2.5.2 contains the last sentence of paragraph 
S6.8.5.6.5, paragraph S14.2.5.3 contains the last sentence of paragraph 
S6.8.5.6, paragraph S14.2.5.4 duplicates paragraph S6.8.5.6.1, 
paragraph S14.2.5.5 duplicates paragraph S6.8.5.6.2, paragraphs 
S14.2.5.5.1 and S14.2.5.5.2 duplicate paragraphs S6.8.5.6.2(a) and 
S6.8.5.6.2(b) respectively, paragraph S14.2.5.5.3 (split for clarity) 
duplicates paragraph S6.8.5.6.2(c), paragraph S14.2.5.5.4 duplicates 
paragraph S6.8.5.6.2(d), paragraph S14.2.5.5.5 (split for clarity) 
duplicates paragraph S6.8.5.6.2(e), paragraph S14.2.5.5.6 (split for 
clarity) duplicates paragraph S6.8.5.6.2(f), paragraph S14.2.5.5.7 
(split for clarity) duplicates paragraph S6.8.5.6.2(g), paragraph 
S14.2.5.5.8 duplicates paragraph S6.8.5.6.2(i), and paragraph 
S14.2.5.5.9 duplicates paragraph S6.8.5.6.2(j). Paragraph S6.8.5.6.2 of 
the NPRM becomes paragraph S14.2.5.6 of the final rule, paragraph 
S6.8.5.6.4 becomes paragraph S14.2.5.7 (split for clarity), paragraph 
S6.8.5.6.5 (less the last sentence) becomes paragraph S14.2.5.8 (split 
for clarity), and paragraph S6.8.5.6.6 becomes paragraph S14.2.5.9. 
Guide commented that paragraph S6.8.5.6.2(h) of the NPRM described 
photometry measurement for moveable reflector headlamps rather than an 
aiming procedure and did not belong where it was located. We agree and 
have designated this provision as paragraph S14.2.5.10 in the final 
rule.
    AAM and Honda objected to the word ``specified'' which appeared 
before ``position relative to the * * *'' in the NPRM. We omitted 
``specified'' in the final rule to be faithful to paragraph S7.8.2.2(b) 
of the current version of FMVSS No. 108. We also added a horizontal 
range exclusion for visually/optically aimed moveable reflector 
headlamps with a fixed horizontal aim to be faithful to paragraph 
S7.8.2.2(d) of the current version of FMVSS No. 108, as noted in the 
comments of Nissan.
    Paragraph S14.3 of the final rule contains the out of focus test 
that was part of Table XXII of the NPRM. This test only applies to 
motorcycle headlamps that are designed to conform to paragraph 
S10.17(b) of the final rule. AAM identified two typographical errors in 
the out of focus test procedure where there were no periods after the 
abbreviations ``in''. Our practice is to not include a period after 
such abbreviations, so the text identified by AAM is correct although 
in several other instances we did include a period after such an 
abbreviation. In the final rule we have removed periods after all such 
abbreviations, except in those situations where other grammatical

[[Page 68254]]

requirements, such as the end of a sentence, require a period.
    Paragraph S14.4 of the final rule, General test procedures and 
performance requirements, contains the color test and plastic optical 
materials test, along with applicable requirements, from Table XXII of 
the NPRM. In both tests, the text as stated in the NPRM has been split 
for clarity in the final rule.
    AAM noted that the Scope of SAE J578c, Color Specification for 
Electric Signal Lighting Devices, February 1977, contains limitations 
on the application of this standard that may be important to lighting 
manufacturers. This portion of SAE J578c was inadvertently left out of 
Table XXII in the NPRM. In the final rule, we have added it as 
paragraph S14.4.1. This section will now read, ``The requirement 
applies to the overall effective color of light emitted by the device 
and not to the color of the light from a small area of the lens. It 
does not apply to any pilot, indicator, or tell-tale lights. The color 
of the sample device * * *''
    Paragraph S14.4.1.1 of the final rule, detailing alternatives for 
samples used in the color test of reflex reflectors, originated from 
the last sentence of paragraph S6.8.2 of the NPRM.
    Koito, 3M, and Honda commented that the language of the performance 
requirement for the color test for the color yellow using the visual 
evaluation method omitted a key word. In the NPRM, the requirement is 
stated as, ``Yellow (Amber) is acceptable if it is less saturated 
(paler), greener, or redder than the limit standard.'' The revised text 
in the final rule states, ``Yellow (Amber) is not acceptable if it is 
less saturated (paler), greener, or redder than the limit standard'' 
[emphasis added].
    AAM commented that the color restricted blue should be included in 
the final rule because it appears in SAE J578c. We know of no 
requirements in Standard No. 108 for the light from a lamp or the color 
of a lens material to be restricted blue. We also observed that there 
are also no such requirements for the colors green or blue. Therefore, 
we have not only decided against adding requirements for restricted 
blue but also have removed the requirements for the colors blue and 
green for both the visual evaluation method and the tristimulus 
evaluation method of the color test of paragraph S14.4.1 in the final 
rule.
    AAM commented that Section 3.2, Tristimulus Method, from SAE J578c 
is not stated in its entirety in the procedure column of the color test 
of proposed Table XXII. We have reviewed SAE J578c and the text of the 
Tristimulus Method procedure from proposed Table XXII. We do not find 
that the text of proposed Table XXII omitted any substantive portion of 
SAE J578c that describes how the test is performed. In the absence of 
any specific explanation of its comments by AAM, we are not revising 
the Tristimulus Method section, now located in paragraph S14.4.1.4 of 
the final rule.
    Paragraph S14.4.2 of the final rule contains the plastic optical 
materials tests from Table XXII of the NPRM. Atlas, Bayer, Grote, and 
AAM commented that the performance requirement for headlamp lens 
materials after the outdoor exposure test portion of the plastic 
optical materials tests in Table XXII of the NPRM was not identical to 
that stated in Section 4.2.3 of SAE J576 JUL91. The language of the 
NPRM stated that the requirement was no haze greater than 0% when 
measured by ASTM D 1033 (1992). SAE J576 JUL91 states the requirement 
as ``shall show no deterioration.''
    Koito noted that while the measurement method of ASTM D 1033 (1992) 
was required for evaluation of the post exposure haze of other 
materials, it was not required for the evaluation of headlamps. Koito 
also stated that the post exposure performance requirements for 
luminous transmittance and color required by SAE J576 at Sections 4.2.1 
and 4.2.2 are missing from the NPRM. We agree with these comments and 
have revised the plastic optical materials test outdoor exposure test 
portion performance requirements accordingly. Specifically, the 
performance requirement section for headlamp lenses, now paragraph 
S14.4.2.2.4.2 of the final rule, no longer requires evaluation by ASTM 
D 1033 (1992) and states, ``After completion of the outdoor exposure 
test, materials used for headlamp lenses must show no deterioration.'' 
The performance requirement section for luminous transmittance, now 
paragraph S14.4.2.2.4.4, states, ``After completion of the outdoor 
exposure test, all materials, when compared with the unexposed control 
samples, must not have their luminous transmittance changed by more 
than 25% when tested in accordance with ASTM E 308-66 (1973) using CIE 
Illuminant A (2856K).'' The performance requirement section for color, 
now paragraph S14.4.2.2.4.5, states, ``After completion of the outdoor 
exposure test, all materials must conform to the color test of this 
standard in the range of thickness stated by the material 
manufacturer.''
    Bayer stated that specifying 2.3 mm thick test samples for the 
plastic optical materials tests represents a change from the current 
version of FMVSS No. 108 and may increase the testing burden of the 
industry. We do not believe that specifying 2.3 mm thick samples is a 
change from current requirements. SAE J576 JUL91 does only suggest 2.3 
mm samples, paragraph S5.2.1 of the current version of FMVSS No. 108 
(and paragraph S5.1 of the NPRM) states that, ``The words `It is 
recommended that', `recommendations', or `should be' appearing in any 
SAE Standard or Recommended Practice referenced or subreferenced by 
this standard shall be read as setting forth mandatory requirements * * 
*'' We consider the term ``suggest'' to have a similar meaning as the 
term ``should be'' and have therefore included 2.3 mm as one of the 
sample thicknesses used for the plastic optical material test. We 
believe there is value in specifying sample thickness. The inclusion of 
the 2.3 mm sample thickness also serves to alert regulated parties that 
should the agency choose to perform a compliance test, it will perform 
the test on this sample thickness.
    AAM suggested eliminating the notation concerning test samples 
having 32 sq cm of exposed area from the Procedure column of Table XXII 
of the NPRM and allowing it to remain in the Samples column of the 
outdoor exposure test portion of the plastic optical materials tests. 
We do not agree with this suggestion. The area requirement is important 
in both the preparation of the samples and their mounting orientation 
for the exposure test. An area specification is appropriate in both 
places and is included in both paragraph S14.4.2.1.2 and paragraph 
S14.4.2.2.3.1 of the final rule.
    The NPRM omitted the third sentence of SAE J576 JUL91 Section 3.3.2 
requiring that samples be mounted in the open with a minimum 30 cm 
(11.8 in) separation from their background. This has been corrected in 
the final rule by including the separation requirement in paragraph 
S14.4.2.2.3.1.
    AAM suggested that content of the Samples column of Table XXII of 
the NPRM for the outdoor exposure test portion of the plastic optical 
material tests be repeated for the heat test portion separately. We 
agree that this would add clarity. We have revised the heat test 
portion of the plastic optical materials tests to appear as a test 
separate from the outdoor exposure test and have placed content 
specific to the heat test into paragraph S14.4.2.3 of the final rule.
    Paragraph S14.5 of the final rule, Signal lamp and reflective 
device test procedures and performance requirements, contains the 
vibration,

[[Page 68255]]

moisture, dust, and corrosion tests that were located in Table XXII of 
the NPRM.
    As previously mentioned, the references in the NPRM to SAE J577, 
Vibration Test Machine, April 1964, have been eliminated in the final 
rule with the incorporation of the drawing and mechanical details of 
the vibration machine as Figure 21. The reference in the vibration test 
procedure to SAE J577 has been revised to Figure 21 in paragraph 
S14.5.1.1 of the final rule.
    AAM, Honda, and Guide commented about the inadvertent omission of 
the phrase ``one hour'' from the moisture test procedure of Table XXII 
of the NPRM. This is corrected in the final rule where paragraph 
S14.5.2.1, second sentence, states, ``* * * followed by a one hour 
drain period * * *''
    We have decided that the first sentence of the moisture test 
performance requirements of the NPRM stating, ``After completion of the 
moisture test * * *'' is more appropriately part of the test procedure. 
Therefore, we are relocating it to be the last sentence of paragraph 
S14.5.2.1 of the final rule.
    Calcoast commented that the moisture test performance requirement 
for a sealed reflex unit stated in SAE J594f, January 1977, at Section 
3.1.4 is ``any visible moisture constitutes a failure.'' We agree and 
have revised the moisture test performance requirements of paragraph 
S14.5.2.2 in the final rule to state ``Accumulation of moisture in 
excess of 2 cc, or any visible moisture in a sealed reflex unit, must 
constitute a failure.''
    AAM noted that the dust test of Table XXII of the NPRM is not 
required to be performed on sealed units per SAE J575d, August 1967, 
Section G, and SAE J575e, August 1970, Section G. We agree and in the 
final rule paragraph S14.5.3.1, Samples states, ``A sealed unit is not 
required to meet the requirements of this test.'' We also decided that 
the first sentence of the performance requirements of the dust test 
stating, ``After completion of the dust test the exterior surface of 
the device must be cleaned'' was part of the test procedure rather than 
a performance requirement so that sentence was moved to paragraph 
S14.5.3.2 in the final rule.
    Paragraph S14.6 of the final rule, Headlamp physical test 
procedures and performance requirements, consists of all headlamp test 
procedures from Table XXIII of the NPRM, except for those that apply 
specifically to replaceable light sources or vehicle headlamp aiming 
devices (VHAD). Several of the tests that become paragraph S14.6 had 
significant portions of their text split for clarity as part of their 
relocation from Table XXIII of the NPRM to paragraph S14.6 of the final 
rule. These tests include: (1) Abrasion test, (2) chemical resistance 
test, (3) corrosion connector test, (4) dust test, (5) temperature 
cycle test, (6) internal heat test, (7) humidity test, (8) sealing 
test, (9) chemical resistance of reflectors of replaceable lens 
headlamps, (10) corrosion resistance of reflectors of replaceable lens 
headlamps, (11) torque deflection test, and (12) both aiming adjustment 
tests.
    Honda commented that the pad cycling rate of the abrasion test 
procedure of Table XXIII of the NPRM contained typographical errors. We 
agree and have revised the text in paragraph S14.6.1.1.3 of the final 
rule from ``11 cycles at 10  cm per second * * *'' to the 
correct language from the current version of FMVSS No. 108 paragraph 
S8.2(b) which is, ``* * * 11 cycles at 4  0.8 in (10  2 cm) per second * * *.''
    AAM stated the requirement that the same sample headlamp be used in 
both the temperature cycle test and the internal heat test was not 
supported in the current version of FMVSS No. 108. We disagree. The 
current version of Standard No. 108 states, concerning integral beam 
headlamps at paragraph S7.4(h)(5), ``The headlamp shall meet the 
requirements of subparagraph (i) and then those of subparagraph (ii) 
[emphasis added]. Subparagraph (i) describes a temperature cycle test 
in accordance with paragraph S8.6.1 and subparagraph (ii) describes an 
internal heat test in accordance with paragraph S8.6.2. Paragraph 
S7.5(h)(i) requires replaceable bulb headlamps to meet the same 
physical tests in paragraphs 7.4(g) and S7.4(h) that are required of an 
integral beam headlamp. Thus, there is a very clear requirement that a 
single headlamp sample be used, in sequence, in the temperature cycle 
test and then the internal heat test.
    Guide and VS commented that the humidity test of Table XXIII of the 
NPRM incorrectly included a performance requirement of post-test 
photometry. We agree, and the post-test photometry provision has been 
removed from the humidity test, which is contained in paragraph 
S14.6.7.2 of the final rule.
    Honda and AAM observed a typographical error in the tolerance for 
air flow uniformity in paragraph (d) of the humidity test procedure. 
The text of the NPRM states, ``* * * each grid point is 10% of the 
average * * *'' while the corrected text of paragraph S14.6.7.1.6 of 
the final rule states, ``* * * each grid point is  10% of 
the average* * *'' which is faithful to paragraph S8.7(d) of the 
current version of FMVSS No. 108.
    As we mentioned in the discussion of paragraph S14.5, the 
references in the NPRM to SAE J577, Vibration Test Machine, April 1964, 
have been eliminated in the final rule with the incorporation of the 
drawing and mechanical details of the machine as Figure 21. The 
reference in the vibration test procedure of Table XXIII of the NPRM to 
SAE J577 has been revised to Figure 21 in the final rule.
    Nissan observed that the applicability of the chemical resistance 
of reflectors of replaceable lens headlamps test and the corrosion 
resistance of reflectors of replaceable lens headlamps test did not 
include integral beam headlamps, as required by paragraph S5.8.11 of 
the current version of FMVSS No. 108. Its comment is correct and 
paragraph S10.14.7.6 of the final rule correctly states the requirement 
for these two tests.
    Koito and Nissan questioned whether the inward force test of Table 
XXIII applied to headlamps other than sealed beams, particularly those 
headlamps that utilize a VHAD or are visually/optically aimed. This 
requirement comes from paragraph S7.8.5.1(b) of the current version of 
FMVSS No. 108. That paragraph states, ``when a headlamp is installed on 
a motor vehicle, its aim in any direction shall not change by more than 
0.30 degree nor shall the lamp recede more than 0.1 in (2.5 mm) after 
being subjected to an inward force of 50 pounds (222 newtons) applied 
evenly to the lens parallel to the mechanical axis.'' There is no 
distinction in this paragraph to any particular type of headlamp, so it 
must be applied to all headlamps.
    Nissan commented that the performance requirements of the aiming 
adjustment test (laboratory) were ``difficult to read'' as presented 
but did not explain the difficulties or suggest alternative language. 
In the final rule, we have split the performance requirements of this 
test into paragraphs S14.6.17.2.1, S14.6.17.2.2, and S14.6.17.2.3, 
which we believe will improve clarity.
    Paragraph S14.7 of the final rule, Replaceable light source 
physical test procedures and performance requirements, consists of the 
deflection test for replaceable light sources and the pressure test for 
replaceable light sources from Table XXIII of the NPRM, along with a 
replaceable light source power and flux measurement procedure. The text 
of all of these items has been split for clarity in the final rule. 
There were no comments submitted that impacted the substance of these

[[Page 68256]]

procedures and requirements. However as mentioned in the discussion of 
paragraph S11, the NPRM contained paragraphs S15.2 and S15.3, both 
titled Power and flux measurement, that essentially described the same 
test of replaceable light sources. We consolidated the procedures of 
paragraphs S15.2 and S15.3 into a single procedure, without revising or 
modifying the requirements, and relocated it to paragraph S14.7.3 of 
the final rule.
    Paragraph S14.8 of the final rule, Vehicle headlamp aiming device 
(VHAD) physical test procedures and performance requirements, consists 
of the six VHAD tests that were part of Table XXIII of the NPRM. There 
were no comments submitted that impacted the substance of these 
procedures and requirements.
    Paragraph S14.9 of the final rule, Associated equipment physical 
test procedures and performance requirements, consists of the tests 
contained in Table XXI of the NPRM. These test procedures and 
performance requirements, as written in Table XXI of the NPRM, were in 
block paragraph form. As we have done in several places throughout the 
final rule, we have split some of these longer paragraphs into several 
smaller sections, which are grouped according to similar content, in an 
effort to improve clarity.
    One of the goals of the FMVSS No. 108 rewrite was to remove 
outdated requirements from the document. The physical test requirements 
for associated equipment presented an opportunity to pursue this goal. 
The applicable SAE documents incorporated by reference in FMVSS No. 108 
were adopted between 1964 and 1969 and several of them contained 
specifications for both vehicles with a nominal 12 volt electrical 
system as well as those with a nominal 6 volt electrical system. 
Believing that few, if any, vehicles manufactured after the effective 
date of FMVSS No. 108 have been equipped with a nominal 6 volt 
electrical system, we deleted references to that voltage in the 
proposal.
    In its comments, AAM requested that we restore the nominal 6 volt 
requirements to the physical test requirements for associated 
equipment. Presumably, this comment was based upon the knowledge that 
one of its constituent organizations was producing a 6 volt device for 
a regulated vehicle or had plans to do so. While we continue to believe 
that those requirements are not currently being used by any regulated 
party, we do not want to eliminate a compliance option that has value. 
Therefore, we have restored the applicable language from the SAE 
documents \26\ incorporated by reference in the current version of 
FMVSS No. 108 for testing devices used in a nominal 6 volt electrical 
system. The restoration of nominal 6 volt requirements necessitated 
revisions in the following portions of paragraph S14.9 of the final 
rule: (1) S14.9.1 turn signal operating unit durability test procedure, 
(2) S14.9.2.2 vehicular hazard warning signal operating unit durability 
performance requirements, and (3) S14.9.3 turn signal flasher and 
vehicular hazard warning signal flasher test procedure and performance 
requirements.
---------------------------------------------------------------------------

    \26\ SAE J589, Turn Signal Operating Units, April 1964; SAE 
J910, Vehicular Hazard Warning Signal Operating Unit, January 1966; 
SAE J945, Vehicular Hazard Warning Signal Flasher, February 1966; 
SAE J590b, Automotive Turn Signal Flashers, October 1965; and SAE 
J823b, Flasher Test Equipment, April 1968.
---------------------------------------------------------------------------

    AAM and Honda commented that the reference in the turn signal 
operating unit durability test procedure in Table XXI of the NPRM 
incorrectly stated the ripple voltage tolerance of the power supply. We 
agree and have revised the language of that procedure in the final 
rule. The text `` * * * ripple voltage of less than 5% * * * was 
changed to `` * * * ripple voltage of not more than 5% * * *.''
    The turn signal flasher and vehicular hazard warning signal flasher 
both maintained their reference to SAE J823b, Flasher Test Equipment, 
April 1968, in the NPRM. As previously mentioned, this document was 
eliminated from the final rule by incorporating its content directly 
into Standard No. 108. This was accomplished in the final rule by 
creating Figure 22, Flasher Standard Test Circuit, for the circuit 
diagram of Figure 1 of SAE J823b, and also by listing the test setup 
requirements of Sections 3 through 9 of SAE J823b in paragraph S14.9.3 
of the final rule as well as the power supply specifications for 
testing performance requirements and those specifications for testing 
durability requirements that were Section 10 of SAE J823b into 
paragraph S14.9.3.2 of the final rule.
    Koito commented on the load requirements (from paragraph S5.1.1.19 
of the current version of FMVSS No. 108) for variable load turn signal 
flashers for the turn signal flasher starting time test and the flash 
rate and percent current ``on'' time test. In the proposal, this 
information was located parenthetically after the notation ``Starting 
time test'' and ``Flash rate and percent current ``on'' time test''. We 
agree with Koito that this is not the optimum location for this 
provision, and have inserted it into the applicable test procedure in 
the final rule. Where those proposed procedures stated ``* * * with the 
design load connected * * *'' the text of the final rule now states ``* 
* * with the design load (variable load flashers are tested with their 
minimum and their maximum design load) connected * * *.''
    Koito and AAM observed that load specifications stated in the 
procedure for the turn signal flasher voltage drop test and durability 
test procedures did not clearly replicate the requirements from 
paragraph S5.1.1.19 of the current version of FMVSS No. 108, and SAE 
J590b, October 1965, Section 2. We have revised the language of those 
procedures in the final rule to clarify the load specifications. The 
proposed procedures stated ``* * * with the maximum design load 
connected * * *'' which has changed in the final rule to state `` * * * 
with the design load (variable load flashers are tested with their 
maximum design load) connected * * *.''
    Honda observed that the durability test performance requirements 
for the vehicular hazard warning signal flasher did not include the 
notation from SAE J945, February 1966, Section 7, requiring the post 
durability test to incorporate pilot lamps as part of the maximum 
design load. We agree and have revised the language of the performance 
requirements in paragraph S14.9.3.10.3 of the final rule from `` * * * 
maximum design load at an ambient * * * '' to ``maximum design load, 
including pilot lamps as specified by the manufacturer, at an ambient* 
* *.''
    Honda, AAM, and Koito all commented that the column headings for 
the semiautomatic headlamp beam switching device sensitivity test 
performance requirements were incorrect. We agree and have revised them 
in paragraph S14.9.3.11.2.3.1 of the final rule. They now read from 
left to right: Test position (degrees) [above the two columns of 
lateral and vertical test points], Dim (cd at 100 ft), and Hold (cd at 
100 ft).
    Honda observed that the maximum dim sensitivity at test point H-5R 
was incorrectly stated in the NPRM as 100 (cd at 100 feet). The correct 
value is 150 (cd at 100 feet) as shown in Table 1 of SAE J565b, 
February 1969. We incorporated this revision in the final rule.
    Koito also commented that the semiautomatic headlamp beam switching 
device voltage regulation test procedure incorrectly refers to ``dim'' 
sensitivity in the NPRM. The correct notation is ``hold'' sensitivity 
and that is

[[Page 68257]]

what appears in paragraph S14.9.3.11.3.1.2 of the final rule.
    AAM commented that the language of the semiautomatic headlamp beam 
switching device warmup test performance requirement of the NPRM was 
not faithful to SAE J565b, February 1969, Section 4.5. We have revised 
that language in paragraph S14.9.3.11.5.2 of the final rule to be 
identical to the first sentence of Section 4.5, specifically, ``If the 
warmup time of the device exceeds 10 seconds, it must maintain the 
headlamps on lower beam during warmup.''
Tables
Table I-a Portion of Proposed Table I
    As mentioned previously, we have decided to split Table I of the 
NPRM into three sections. Table I-a lists lamp and reflective device 
requirements for passenger cars, multipurpose passenger vehicles, 
trucks, and buses of all widths. Where we refer to comments about the 
content of Table I-a, it indicates that those comments were submitted 
about the content of the portion of Table I of the NPRM now contained 
in Table I-a of the final rule.
    Based on comments submitted to the docket regarding our proposal, 
we have decided to make several revisions to Table I-a. One of these 
revisions was the inclusion of the abbreviation ``MPV'' in parenthesis 
after the term ``Multipurpose Passenger Vehicle'' in the title of Table 
I-a. We have subsequently used this abbreviation several times in this 
document.
    Guide commented that the reference in Table I for the number and 
color of headlamps does not directly state a number but instead makes 
an additional reference to Table II. We do not find this method 
difficult or complex, it somewhat duplicates the method of the current 
version of FMVSS No. 108. Sub-referencing is necessary because the 
number of headlamps actually used depends on the headlighting system 
chosen. We clarified the language of Table I-a for the number of upper 
beam and lower beam headlamps from `` * * * type and number * * * '' to 
`` * * * headlighting system * * * '' to more precisely describe this 
sub reference.
    AAM and Koito commented about the inclusion of the phrase `` * * * 
equal to or wider than the upper beam headlamps'' in the mounting 
location description for lower beam headlamps along with the 
corresponding phrase `` * * * equal to or narrower than the lower beam 
headlamps'' in the mounting location description for the upper beam 
headlamps. They, along with Honda, which commented about the same 
language in Table I relating to motorcycle headlamps, believe that this 
phrase is inconsistent with the current FMVSS No. 108 requirement. We 
agree that it does not fully describe the relationship required between 
upper and lower beam headlamps. We removed this language from Tables I-
a and I-c of the final rule and incorporated headlamp beam spacing 
requirements in paragraph S6.1.3.5.
    AAM commented that the activation requirement for turn signal lamps 
stating, ``Current 108 paragraph S5.1.1.19 references SAE J590b * * * 
in which Figure 1 combines flash rate and percent current ``on'' time. 
This figure appears as Figure 2 in Rewrite 108. There is no reference 
to percent current ``on'' time in Rewrite 108 Table I. We are unable to 
find a reference to Rewrite Figure 108 anywhere within the Rewrite 108 
text.'' The reference to NPRM Figure 2 is contained in Table XXI which 
details the performance of turn signal (and vehicular hazard warning 
signal) flashers, specifically in the performance requirements for the 
Flash Rate and Percent Current ``On'' Time Test. We agree that 
including the rate of 60 to 120 flashes per minute in Table I is a 
detail that is not needed. The flash rate will be determined by the 
choice of flasher and its performance when subjected to the test of 
paragraph S14.9.3. Therefore, we are revising the Device Activation 
requirement for turn signal lamps in Table I-a (and the corresponding 
requirement in Table I-b for trailers and in Table I-c for motorcycles) 
to read, ``Flash when the turn signal flasher is actuated by the turn 
signal operating unit.'' This statement more accurately describes the 
process by which the turn signal lamps are caused to flash.
    AAM, Honda, and Koito commented about the activation requirements 
for taillamps, side marker lamps, and license plate lamps with respect 
to their required activation when the parking lamps are activated. AAM 
contended that the NPRM does not clearly state that the taillamps, side 
marker lamps, and license plate lamps are required to be activated when 
the parking lamps are activated only on vehicles less than 2032 mm in 
overall width. To clarify those requirements, we revised the language 
of the activation requirement from * * * ``Must be activated when the 
headlamps are activated in a steady burning state or the parking lamps 
are activated (not a requirement for vehicles 2032 mm or more in 
overall width)``, to * * * ``Must be activated when the headlamps are 
activated in a steady burning state or the parking lamps on passenger 
cars and MPVs, trucks, and buses less than 80 inches in overall width 
are activated.'' This revision was made to the Device Activation 
requirements for taillamps, side marker lamps, intermediate side marker 
lamps, and license plate lamps in Table I-a.
    AAM also commented that the activation requirement for a stop lamp 
optically combined with a turn signal lamp was not stated in Table I 
using the language from SAE J586 FEB84, at Section 5.4.2 and SAE J1398 
MAY85, also at Section 5.4.2. One of the stated intentions of the 
rewrite is to clarify requirements without making substantive changes 
to them. Although we were satisfied with the language of the NPRM in 
this situation, we revised the language to be faithful to the original 
SAE language. We replaced the third sentence of the Device Activation 
requirement for stop lamps in Table I-a with ``When a stop signal is 
optically combined with the turn signal, the circuit must be such that 
the stop signal cannot be turned on if the turn signal is flashing.'' 
Identical revisions have been made in Table I-b for trailers and Table 
I-c for motorcycles.
    We have corrected an omission in Table I-a with respect to the 
requirements applicable to a truck tractor. The current version of 
FMVSS No. 108 excludes, in paragraph S5.1.1.2, a truck tractor from 
being required to be equipped with any rear side marker devices, rear 
clearance lamps, and rear identification lamps. The NPRM included this 
exclusion for rear side marker lamps, rear clearance lamps, and rear 
identification lamps but failed to include the notation for rear side 
reflex reflectors. This has been corrected in the final rule.
    TTMA stated in its comments that the partial photometric output 
exclusion for clearance lamps mounted other than on the front or rear 
of a vehicle where necessary to indicate overall vehicle width or 
protect the lamps from damage, appearing in paragraph S5.3.2.1 of the 
current version of FMVSS No. 108, does not appear in the NPRM. The 
exclusion for mounting location does appear in the Mounting Location 
portion of Table I-a for both front and rear clearance lamps (and has 
been added to Table I-b for trailer clearance lamps). The photometric 
output exclusion for such lamps appears in Table XI as Footnote 4, 
which is the appropriate location for this detail.
    TTMA also called attention to an interpretative rule issued by the 
agency in 1999 and published at 64 FR 16358 \27\

[[Page 68258]]

which quantifies the requirement that clearance lamps and 
identification lamps be mounted ``as near the top as practicable'' and 
describes how ``practicability'' will be determined for these lamps 
when mounted on a vehicle with cargo doors. We agree that this 
interpretative rule concerning presumption of practicability is 
important to include in FMVSS No. 108. Therefore, we have added to the 
Mounting Height portion of Table I-a, applicable to rear clearance 
lamps and rear identification lamps (and to those same lamps in Table 
I-b applicable to trailers), the sentence ``Practicability of locating 
lamps on the vehicle header is presumed when the header extends at 
least 25 mm (1 inch) above the rear doors.''
---------------------------------------------------------------------------

    \27\ 64 FR 16358, (April 5, 1999).
---------------------------------------------------------------------------

    ASSN commented that the incorporation of the May 26, 2000 letter of 
interpretation to Mr. Farber \28\ permitting stop lamps to be activated 
when a vehicle is slowed by a device designed to retard the motion of a 
vehicle, should also be extended to activation of a high-mounted stop 
lamp. The Farber interpretation was issued several years after high-
mounted stop lamps were first required on vehicles but does not 
explicitly address their activation. The current version of FMVSS No. 
108 contains, in paragraph S5.5.4, slightly different activation 
requirements for stop lamps and for high-mounted stop lamps. It states, 
``The stop lamps on each vehicle shall be activated upon application of 
the service brakes. The high-mounted stop lamp on each vehicle shall be 
activated only upon application of the service brakes'' (emphasis 
added). This difference in activation requirements is explained in the 
September 10, 1990 letter of interpretation to Mr. Henneberger \29\ 
which states, `` * * * The second sentence of S5.5.4 restricts 
operation of the center stop lamp to application of the service brakes, 
but no such restriction exists in the first sentence. Although the 
first sentence requires operation of the stop lamps upon application of 
the service brakes, when considered in conjunction with the restriction 
stated in the second sentence, it can be read as implying that there 
may be other conditions under which activation of the stop lamps is 
permissible. However the reason for the difference in the two sentences 
is otherwise. Commonly, in red rear combination lamps, the same 
filament serves both the stop and turn signal functions. If the turn 
signal is functioning when the brakes are applied, the first sentence 
ensures that the stop signal overrides the turn signal.''
---------------------------------------------------------------------------

    \28\ http://isearch.nhtsa.gov/files/21341.ztv.html    \29\ http://isearch.nhtsa.gov/gm/90/nht90-3.93.html

    The Farber interpretation was incorporated into the NPRM because of 
its conclusion that, `` * * * when a vehicle is slowed by downshifting 
or an engine retarder, from the perspective of the following driver, it 
would be equivalent to what would occur if the service brakes were 
applied. Therefore, it would be permissible for the stop lamps to be 
illuminated under this scenario, since such illumination would not 
create any confusion in the mind of a following driver and thus would 
not ``impair the effectiveness'' of the required stop lamps.'' Clearly, 
the Farber interpretation establishes a situation where the action of a 
retarder or similar device is equivalent to the action of applying the 
service brakes. Since S5.5.4 of the current version of FMVSS No. 108 
requires activation of the high-mounted stop lamp when the service 
brake is applied, it follows that it may also be activated by 
application of a retarder. Table I-a of the final rule has been revised 
to include this permitted activation.
    AAM recognized a typographical error in Table I-a in describing the 
mounting location requirements for school bus signal warning lamps. AAM 
suggested language that is more faithful to that of SAE J887, School 
Bus Red Signal Lamps, July 1964, the document incorporated by reference 
in the current version of Standard No. 108. We have revised the 
language of the final rule applicable to the mounting location of these 
lamps to state, `` * * * but in no case shall the spacing between lamps 
be less than 40 inches'', which is more faithful to SAE J887.
    Nissan commented that inclusion of the Daytime Running Lamp (DRL) 
in a Table titled Required Lamps and Reflective Devices implied that 
the DRL was the only non-required lamp permitted on regulated vehicles. 
We have discussed previously that we believe Table I-a is the 
appropriate location for the DRL in the standard. However, we have 
clarified the portion of Table I-a applicable to the DRL by revising 
the title from ``Additional Lamps Allowed * * *'' to ``Daytime Running 
Lamps Allowed * * *.''
    Nissan and AAM commented that Table I-a did not completely describe 
all mounting height restrictions on DRLs in the appropriate portion of 
the table. We have clarified in Table I-a that additional requirements 
do apply and are included in paragraph S7.10.13(b) of the final rule.
    Guide commented that additional DRL activation requirements are 
contained in paragraph S7.11.2 of the NPRM and should be added to Table 
I-a. We disagree. There is language in Table I-a calling attention to 
these additional requirements and directing users to paragraph 
S7.10.10.1(c) of the final rule, a notice that we believe is adequate.
Table I-b Portion of Proposed Table I
    In addition to those revisions to Table I-b that were listed in the 
preceding section, several others have been incorporated in the final 
rule.
    AAM commented that the width criteria for installing a single 
taillamp, stop lamp, or rear reflex reflector on a trailer was 
incorrectly dimensioned. Table I-b stated that the installation of a 
single such device can occur ``* * * on trailers less than 760 mm 
wide.'' The correct dimension from paragraph S5.1.1.14 of the current 
version of FMVSS No. 108 is 30 inches, and the final rule states that 
dimension for all three devices. Current paragraph S5.1.1.14 also 
states that when single devices are used, they shall be located ``* * * 
at or near its vertical centerline.'' To clarify this requirement, we 
have revised the Mounting Location requirement language from ``A single 
lamp (reflector) must be mounted at or near the vertical centerline'' 
to ``When a single lamp (reflector) is installed, it must be mounted at 
or near the vertical centerline.''
    AAM, Grote, and Koito all commented that the NPRM did not include 
the mounting height limitation of 60 inches for rear side marker lamps 
installed on trailers 2032 mm or more in overall width, which is stated 
in Table II of the current version of FMVSS No. 108. This omission is 
corrected in Table I-b in the final rule.
    TTMA commented on the appropriate location for the requirement 
stating that conspicuity treatment on a trailer can serve as the 
required reflex reflectors if the conspicuity treatment is placed at 
the locations required for reflex reflectors. This alternative is 
contained in paragraph S6.1.1.1.1 in the NPRM, but we agree it is best 
located in Table I-b and have moved it there, following the listing of 
``Reflex Reflectors'' and ``Intermediate Reflex Reflectors'', and have 
eliminated paragraph S6.1.1.1.1 from the final rule.
    TTMA commented that the requirements for mounting height for 
clearance lamps and identification lamps in Table I-b was missing. We 
have corrected this by adding the appropriate language from Table II of 
the current version of FMVSS No. 108,

[[Page 68259]]

``As near the top as practicable.'' We have also added language to the 
Mounting Height portion of the rear clearance lamp section stating 
that, similar to Table I-a, they are not required to be mounted as near 
the top as practicable when the rear identification lamps are mounted 
at the extreme height of the vehicle, an exclusion provided by 
paragraph S5.3.1.4 of the current version of FMVSS No. 108 and 
inadvertently omitted from the NPRM.
Table I-c Portion of Proposed Table I
    Consistent with the revision in language to the Number and Color 
portion of headlamps in Table I-a, we have revised Table I-c. It 
previously stated ``* * * of a type and number listed * * *,'' but now 
states ``* * * of a headlighting system listed * * *.'' We believe that 
this revision more precisely describes this requirement.
    AAM commented that there are additional motorcycle headlamp 
mounting restrictions that are not acknowledged in Table I-c. We agree 
and have added language to direct the reader to paragraphs S10.17.1.1, 
S10.17.1.2, and S10.17.1.3 of the final rule for additional headlamp 
mounting requirements.
    We have inserted the language ``a turn signal'' between the words 
``between'' and ``lamp'' in the last sentence of the Mounting Location 
portion of the front turn signal lamp requirements section of Table I-c 
of the final rule to clarify that requirement. Also, the language of 
the last sentence of the Mounting Location portion of the rear turn 
signal lamp requirements section of Table I-c was revised so that it 
now states, ``* * * between the turn signal lamp and taillamp or stop 
lamp is 4 inches * * *,'' a change that clarifies the requirement in 
the final rule.
Table II-a Headlighting Systems--Sealed Beam
    GE, Honda, AAM, and Koito commented that the reference to 
photometry requirements in Table XIX of the NPRM for a lower beam 
visual aim ``LF'' headlamp erroneously stated ``LB1(1)'' 
rather than ``LB1V(1).'' We agree and this has been 
corrected in the final rule.
Table II-b Headlighting Systems--Combination
    GE, Honda, AAM, and Koito commented that the reference to 
photometry requirements in Table XIX of the NPRM for a 4 lamp system, 
lower beam visual aim headlamp erroneously stated ``LBV(4)'' 
rather than ``LB1V(4).'' We agree and this has been 
corrected in the final rule.
    Koito commented that if an integral beam headlamp was used in a 
combination headlighting system, it could consist of beam contributors 
and if so, they would be subject to the photometric allocation formula 
described in paragraph S6.8.5.6.6 of the NPRM. Koito requested that a 
footnote be added to call attention to that possibility. We agree and 
have added Footnote 7 to the final rule stating ``Beam contributor 
photometric allocation formula of paragraph S14.2.5.9 may apply.''
Table II-c Headlighting Systems--Integral Beam
    Footnote 6 was revised for clarity in the final rule to read, 
``Beam contributor photometric allocation formula of paragraph 
S14.2.5.9 applies.''
    Koito commented that the lower beam photometry requirements 
reference in the NPRM for the headlamp in a four lamp system that 
provides a portion of the upper beam and the lower beam should be 
``LB3M'' rather than ``LB4M'' for a mechanically aimed headlamp and 
``LB3V'' rather than ``LB2V'' for a visually/optically aimed headlamp. 
These references are taken from paragraph S7.4(a)(1)(iii) of the 
current version of FMVSS No. 108, which specifies Figure 28-1 or Figure 
28-2. LB4M is a restatement of the requirements of Figure 28-1 and LB2V 
similarly of Figure 28-2.\30\ We do not agree with Koito's comment and 
are therefore making no revision in the final rule.
---------------------------------------------------------------------------

    \30\ And also Figure 17-2 which has identical requirements.
---------------------------------------------------------------------------

Table II-d Headlighting Systems--Replaceable Bulb
    AAM and Koito commented that the references in Table II-d to 
photometry requirements in Table XIX for UB1, LB1M, and LB1V should 
include Footnote 4, ``Lower beams may remain activated when upper beams 
are activated,'' based upon paragraph S5.8.8 of the current version of 
FMVSS No. 108. We agree that the UB1, LB1M, and LB1V requirements are 
derived from Figures 15-1 and 15-2 of the current version of FMVSS No. 
108. Paragraph S5.8.8 states that a headlighting system designed to 
conform to the photometric requirements of Figures 15-1 and 15-2 may be 
so wired. That footnote has been added to the final rule.
    Koito and AAM commented that the photometric requirement reference 
in Table II-d of the NPRM for the upper beam of a 2 lamp system with a 
light source composition of HB2 or any single filament type used alone 
or with any other single or dual filament type, should include UB3 
(Figure 27-1 or 27-2 in the current version of FMVSS No. 108) as well 
as the listed UB2 (Figure 17-1 or 17-2 in the current version of FMVSS 
No. 108). They provide the rationale that this is permitted by 
paragraph S7.5(d)(2)(ii)(A)(1) of the current version of FMVSS No. 108. 
Indeed, a literal reading of that text could lead to such a conclusion. 
However, Figure 26, Table for Determining the Photometric Requirements 
of Replaceable Bulb Headlamp Systems, of the current version of FMVSS 
No. 108 clearly shows, in the box where the row marked ``Two-Headlamp 
System'' intersects the column marked ``HB2 or Any Single Filament Type 
used Alone or with Any Other Single or Dual Filament Type,'' that the 
applicable photometry requirements are those of Figure 17-1 or 17-
2.\31\ Faced with the seeming contradiction between paragraph S7.5 
(d)(2)(ii)(A)(1) and Figure 26, we looked for other cues in FMVSS No. 
108 that would confirm the correct requirement. One such cue is in 
paragraph S7.5(b) which states that, ``The photometrics as specified in 
subparagraphs (c) through (e) of this paragraph (depicted in Figure 
26), using any light source of the Type intended for use in such 
system.'' This clearly indicates that paragraph S7.5 and Figure 26 
provide identical information. Another cue is the language in paragraph 
S7.5(d)(2)(i)(A)(2) which states that only the photometry requirements 
of Figure 17-1 or 17-2 are to be used for lower beam with a two lamp 
system that uses an HB2 source.
---------------------------------------------------------------------------

    \31\ The current version of FMVSS 108 presents headlamp 
photometry requirements in sets of related tables that differ only 
by application to type of aiming system used. In this instance Table 
17-1 applies to mechanically aimed headlighting systems while Table 
17-2 applies to visually/optically aimed headlighting systems.
---------------------------------------------------------------------------

    The specific language of paragraph S7.5(d)(2)(ii)(A)(1) first 
appeared in Standard No. 108 several years ago during a revision in 
text. Instead of concluding with ``* * * light sources that include 
Type HB2 * * *'' paragraph S7.5(d)(2)(ii)(A)(1) should have concluded 
with ``* * * light sources other than Type HB2 * * *'' This would make 
it consistent with paragraph S7.5(d)(2)(i)(A)(1), which addresses the 
lower beam, and Figure 26.
    Because this ambiguity has existed for a considerable length of 
time, it would be a substantive change to revise it in the final rule 
and thus is outside the scope of the rewrite. We have revised

[[Page 68260]]

Table II-d in the final rule to indicate that UB3 may be used as an 
upper beam photometry requirement for a 2 lamp system using a Type HB2 
or any single filament type used alone, or with any other single or 
dual filament type. However, regulated parties should be aware that we 
consider this to be incorrect and we may take action soon to correct 
what we believe is a mistake.
Table III Conspicuity Systems Requirements Becomes Table III Marking 
Requirements Location
    The recognition that the tabular method of organization did not 
work well for the presentation of lengthy textual requirements provided 
the rationale for moving the conspicuity systems requirements content 
of Table III of the NPRM to paragraph S8.2 of the regulatory text of 
the final rule. The substantive issues raised by public comment and the 
revisions to conspicuity systems are discussed under paragraph S8.2. As 
discussed under paragraph S6.5, Table III has been re-designated as a 
source for listing each location in the regulatory text of the final 
rule applicable for each marking requirement of Standard No. 108.
Table IV Effective Projected Luminous Lens Area Requirements
    As previously mentioned, this table has been divided into three 
sections in the final rule.
    Koito and Guide commented that the effective projected luminous 
lens area requirements for a front turn signal lamp were incorrectly 
stated in what is now Table IV-a and did not agree with the 
requirements of SAE J588 NOV84. We concur and have clarified those 
requirements in the final rule to indicate that there is no effective 
projected luminous lens area requirement for each compartment of a 
multiple compartment front turn signal lamp.
    There were no comments submitted that impacted what are now Tables 
IV-b and IV-c in the final rule.
Table V Visibility Requirements of Installed Lighting Devices
    As previously mentioned, this table has been divided into four 
sections. AAM suggested that the column marked ``Applicable Vehicles'' 
was not needed. We agree and have removed it from all four sections of 
Table V in the final rule.
Table V-a Visibility Requirements of Installed Lighting Devices
    AAM suggested alternative language referring to the required 
visibility of high-mounted stop lamps when two lamps are installed. We 
agree with its suggestion and have revised the language of the final 
rule appearing in parenthesis to read (Single lamp or two lamps 
together where required by paragraph S6.1.1.2 of this standard.)
Table V-b Visibility Requirements of Installed Lighting Devices (Lens 
Area Visibility Option)
    Grote suggested that the mandatory enforcement dates for the 
exclusive use of the visibility options of Table V-b and V-c be 
included in those tables. We believe it is preferable to include these 
dates in paragraph S6.4.4 of the regulatory text of the final rule, 
where additional details about choosing a visibility compliance method 
are located.
    AAM suggested that the language of Footnote 2 of Table V-b (and 
Footnote 2 of Table V-c) be revised for clarity. We agree and those 
footnotes now read in the final rule, ``Where a lamp is mounted with 
its axis of reference less than 750 mm above the road surface, the 
vertical test point angles located below the horizontal plane subject 
to visibility requirements may be reduced to 5[deg] down.''
Table V-c Visibility Requirements of Installed Lighting Devices 
(Luminous Intensity Visibility Option)
    AAM claimed that the visibility requirements specifying corner 
points at 80[deg] outboard are erroneous. We disagree because these 
corner points are faithful to those stated in Figure 20 of the current 
version of FMVSS No. 108.
Table V-d Visibility Requirements of Installed Lighting Devices (Legacy 
Visibility Alternative)
    AAM identified a typographical error in the proposal where a period 
did not directly follow the abbreviation ``mm'' in the required 
visibility of turn signal lamps. This has been corrected in the final 
rule by removing all periods after these abbreviations in keeping with 
the style of regulatory text.
    Nissan believed that the term ``existing'' in the parenthetical 
subtitle of this section was indeterminate and suggested it be removed. 
We decided to revise the subtitle from ``(Existing SAE Visibility 
Alternative)'' to ``(Legacy Visibility Alternative)'' in the final rule 
suggesting that these requirements are ones that have historically been 
used.
    Guide commented that the sentence ``Where more than one lamp or 
optical area is lighted on each side of the vehicle, only one such area 
on each side need comply'' should not be included in visibility 
requirements. We disagree because it is an integral part of the SAE 
documents incorporated by reference in the current version of FMVSS No. 
108.\32\
---------------------------------------------------------------------------

    \32\SAE J1395 APR85, S5.4.1, SAE J586 FEB84, S5.4.1, SAE J1398 
MAY85, S5.4.1, and SAE J585e, September 1977, S4.
---------------------------------------------------------------------------

    Guide also suggested that the phrase ``To be considered visible'' 
preface the specific visibility requirements in Table V-d. We believe 
that the language of the requirements in Table V-d, along with the text 
of paragraph S6.4.4, clearly describe what is required and the 
additional language is not needed.
    We have revised the visibility requirement minimum value for a 
taillamp in Table V-d from 1250 sq mm to 2 sq in to be faithful to the 
language of SAE J585e, September 1977, Section 4, incorporated by 
reference in the current version of FMVSS No. 108, which is the 
original source of this requirement.
Table VI Front Turn Signal Lamp Photometry Requirements
    As previously mentioned, this table has been divided into two 
sections. Table VI-a contains the base front turn signal lamp 
photometry requirements and the 2.5 times base front turn signal lamp 
photometry requirements. Table VI-b contains the 1.5 times base and the 
2.0 times base front turn signal lamp photometry requirements.
    Nissan, AAM, and Koito commented that displaying the ratio 
requirements for both turn signal lamps combined with parking lamps and 
turn signal lamps combined with clearance lamps in the same column of 
our proposal was confusing. We agree and have placed the requirements 
for those two combinations in separate columns in both Tables VI-a and 
VI-b in the final rule.
    Koito and AAM commented that Footnote 4 does not accurately state 
the requirements of SAE J1395 AP85, Section 5.1.5.2, incorporated by 
reference in the current version of FMVSS No. 108. We agree and have 
revised that footnote in the final rule to read ``When a clearance lamp 
on a vehicle 2032 mm or more in overall width is combined with a front 
turn signal lamp and the maximum luminous intensity of the clearance 
lamp is located below horizontal and within a 1.0[deg] radius around 
the test point, the ratio for the test point may be computed by using 
the lowest value of the clearance lamp luminous intensity within the 
generated area.''
    AAM noted several instances where the group minimum photometric 
intensity values for 2 and 3 lighted sections, 2.5x base photometry 
lamps, were erroneous. These five values were

[[Page 68261]]

all 0.5 cd less than their calculated values. The correct values have 
been incorporated in Table VI-a in the final rule.
    Koito suggested that several of the group minimum photometric 
intensity values for 2 lighted sections, base photometry lamps, are 
erroneous. Koito appears to have based its comment on the observation 
that the arithmetic sum of the minimum values of all test points 
included in the groups exceeds the value shown for the group. However, 
in this case all of the listed values are accurate. They are consistent 
with values of Table 1 for group requirements and Table 3 for 
individual test point requirements of SAE J588 NOV84, incorporated by 
reference in the current version of Standard No. 108. Although in most 
cases SAE has specified that group photometric values equal the sum of 
the individual test point values in a group, there are exceptions, and 
this is one of those exceptions.
Table VII Rear Turn Signal Photometry Requirements
    Footnote 6 of the final rule was revised to agree with the decision 
to eliminate the reference to SAE J588e for double faced turn signal 
lamps installed on truck tractors. It now reads, ``A double-faced turn 
signal lamp installed as described in paragraph S6.1.1.3 on a truck 
tractor need only meet the photometric requirements for a left side 
lamp where the lamp is mounted on the left side of the vehicle, and for 
a right side lamp where the lamp is mounted on the right side of the 
vehicle.''
Table VIII Taillamp Photometry Requirements
    Calcoast commented that Footnote 1 and Footnote 2 to Table VIII of 
the NPRM are not mutually exclusive. Therefore, the limitations imposed 
by compliance with one of these footnotes may negate an allowance 
offered by the other. We agree with Calcoast's assessment. The 
situation that it mentioned actually affects all lamps where grouped 
test point photometric compliance is permitted. The requirements of 
Footnote 1 of Table VIII also apply to all other lamps where grouped 
compliance is permitted. The original source of this requirement is SAE 
J575, Test for Motor Vehicle Lighting Devices and Components, paragraph 
J, which is identical in both J575d, August 1967, and J575e, August 
1970, the two versions of this standard applicable to signal lamps in 
FMVSS No. 108. Footnote 2 of Table VIII describes the basic premise of 
grouped compliance. The failure of an individual test point in the 
group to meet its minimum photometric intensity can be offset if one or 
more of the other points in the group exceed their minimum intensity 
requirement by enough margin that the group total intensity is still 
met.
    Additionally, turn signal lamps and stop lamps, including high-
mounted stop lamps, also have a further limitation from their original 
SAE source document concerning how much any individual test point can 
fail to meet its minimum intensity when considered in a group 
compliance situation. This limitation states that the measured value at 
each test point must not be less than 60% of the minimum value.
    All these limitations must be considered simultaneously when 
determining grouped photometric compliance for lamps where that 
procedure is permitted. Calcoast was correct in its assessment that 
these limitations may negate full utilization of each other.
    Koito and AAM identified two minimum test point photometric 
intensity values for 3 lighted section lamps they believe are 
erroneous. We agree and have corrected the values at 5L-10D and 5R-10D 
in the final rule.
    We have also revised Table VIII in the final rule to reduce 
confusion by placing the minimum and maximum photometric intensity 
values in separate columns for each of the lighted sections 
alternatives.
    Koito commented that Table VIII did not include Footnote 5 from 
Table 1 of SAE J585e, Tail Lamps (Rear Position Lamps), September 1977, 
incorporated by reference in the current version of FMVSS No. 108. This 
footnote limits the size of the area of maximum photometric intensity 
in a specified portion of the photometric pattern. This requirement was 
added to Table VIII in the final rule and now reads, ``A taillamp shall 
not exceed the maximum intensity over any area larger than that 
generated by a 0.25[deg] radius, within a solid cone angle from 
20[deg]L to 20[deg]R and from H to 10[deg]U.''
Table IX Stop Lamp Photometry Requirements
    The alternative photometric intensity requirements for a stop lamp 
installed on a motor driven cycle that were included in Table IX in the 
NPRM have been relocated to new Table XIII in the final rule. This 
relocation means that Footnote 5 is no longer needed in Table IX and it 
has been eliminated. Footnote 7 of the NPRM has been redesignated as 
Footnote 5 in the final rule.
    Honda, AAM, and Koito all observed an erroneous group minimum 
photometric intensity value for 3 lighted sections in group 3. The 
correct value is 520 cd instead of the listed 445 cd. This error is 
corrected in Table IX of the final rule.
    In Table IX of the NPRM, it was stated that when a stop lamp is 
combined with a taillamp, the luminous intensity of the stop signal 
must exceed the luminous intensity of the tail signal at each test 
point by a certain minimum ratio. This ratio value is common for all 
vehicles at all test points with the exception of the test point H-
5L.\33\ Proposed Table IX showed the ratio value at this point as 3/5 
\(6)\ and further states at Footnote 6, ``Values preceded by a slash (/
) apply only to lamps installed on multipurpose passenger vehicles, 
trucks, trailers, and buses, of 2032 mm or more in overall width.'' 
Thus, the requirement at the H-5L test point is that the luminous 
intensity of the stop lamp exceed the luminous intensity of the 
combined taillamp by at least 3 times on multipurpose passenger 
vehicles, trucks, trailers, and buses, of 2032 mm or more in overall 
width, and by at least 5 times on other applicable vehicles which 
includes all passenger cars and motorcycles and all multipurpose 
passenger vehicles, trucks, trailers, and buses, less than 2032 mm in 
overall width. This discrepancy exists due to the language from which 
the ratio requirements are derived. SAE J586 FEB84, Stop Lamps for use 
on Motor Vehicles Less Than 2032 mm in Overall Width, incorporated by 
reference in the current version of FMVSS No. 108 states in Section 
5.1.5.3, ``When a tail lamp is combined with the stop lamp, the stop 
lamp shall not be less than three times the luminous intensity of the 
tail lamp at any test point; except that at H-V, H-5L, H-5R, and 5U-V, 
the stop lamp shall not be less than five times the luminous intensity 
of the tail lamp.'' Similarly, SAE J1398 MAY85, Stop Lamps for use on 
Motor Vehicles 2032 mm or More in Overall Width, incorporated by 
reference in the current version of FMVSS No. 108, states in Section 
5.1.5.2, ``When a tail lamp is combined with the stop lamp, the stop 
lamp shall not be less than three times the luminous intensity of the 
tail lamp at any test point; except that at H-V, H-5R, and 5U-V, the 
stop lamp shall not be less than five times the luminous intensity of 
the tail lamp.'' Thus, the requirements are identical with the 
exception of test point

[[Page 68262]]

H-5L. By not specifically identifying H-5L as a test point requiring a 
5:1 ratio, SAE J1398 MAY85, by default, requires a 3:1 ratio.
---------------------------------------------------------------------------

    \33\ In the final rule we have elected to implement a suggestion 
by Calcoast to identify photometric test points consistently in the 
photometric requirements tables. We have chosen to list lateral 
values in the left column and vertical values in the right column. 
Thus the H-5L test point of Table IX of the NPRM appears as test 
point 5L-H in the final rule.
---------------------------------------------------------------------------

    SAE J585e, Tail Lamps (Rear Position Lamps), September 1977, also 
incorporated by reference in the current version of FMVSS No. 108 
(applicable to all vehicles), also contains a ratio requirement. 
Footnote 4 to Table 1 of that document states, ``When a tail lamp is 
combined with the turn signal lamp or the stop lamp, the signal lamp or 
stop lamp shall not be less than three times the candlepower \34\ of 
the tail lamp at any test point; except that at H-V, H-5L, H-5R, and 
5U-V, the signal lamp or stop lamp shall not be less than five times 
the candlepower of the tail lamp.'' Thus, there is a documented 
conflict regarding the ratio requirement at the H-5L test point on 
combined stop lamps and taillamps used on wide vehicles. We resolved 
this in the final rule by maintaining the dual requirements stated in 
the NPRM. That is the ratio of stop lamp intensity to taillamp 
intensity at that test point remains 3:1 for lamps installed on 
multipurpose passenger vehicles, trucks, trailers, and buses, of 2032 
mm or more in overall width, and 5:1 for lamps installed on all 
passenger cars and motorcycles and all multipurpose passenger vehicles, 
trucks, trailers, and buses, less than 2032 mm in overall width.
---------------------------------------------------------------------------

    \34\ The term ``candlepower'' used in this context means the 
contemporary unit of measurement used to express the luminous 
intensity attribute.
---------------------------------------------------------------------------

    Although we believe there is ample evidence that the 3:1 ratio was 
never intended by SAE, to rectify this error at this time would 
constitute a substantive change and therefore be beyond the scope of 
the FMVSS No. 108 rewrite. We may address this issue in the near 
future.
Table X Side Marker Photometry Requirements
    Footnote 1 was revised to be more consistent with paragraph 
S7.4.1.1 of the NPRM (paragraph S7.4.13.2 of the final rule) concerning 
the widths of vehicles that can use reduced photometric compliance 
angles between the front and rear side marker. Footnote 1 now reads, 
``Where a side marker lamp installed on a motor vehicle less than 30 
feet in overall length and less than 80 inches (2 m) in overall width 
has the lateral angle nearest the other required side marker lamp on 
the same side of the vehicle reduced from 45[deg] by design as 
specified by S7.4.13.2, the photometric intensity measurement may be 
met at the lesser angle.'' The change in width from 2032 mm to 80 
inches (2 m) was made to be faithful to Footnote b of SAE J592e, 
Clearance, Side Marker, and Identification Lamps, July 1972.
Table XI Clearance and Identification Lamps Photometry Requirements
    Koito and AAM commented that Footnote 3 to Table XI did not include 
the limitation on a turn signal lamp combined with a red clearance lamp 
as required by SAE J592e, July 1972, Table 1 Footnote ``a'', 
incorporated by reference by the current version of FMVSS No. 108. This 
is corrected in the final rule.
    Grote believed that the maximum photometric intensity for a red 
clearance lamp should be 18 cd. We disagree because SAE J592e, July 
1972, incorporated by reference in the current version of FMVSS No. 
108, states in Footnote ``a'' to Table 1 that 15 cd is the maximum 
allowed for a red clearance lamp.
Table XII Backup Lamp Photometry Requirements
    Guide commented that Footnotes 2 and 3 only apply to groups 1, 2 5, 
and 6. We agree. Figure 2, Footnote 1 of the current version of 
Standard No. 108 is the source of these requirements and the Guide 
assertion is consistent with that figure. We revised Table XII 
accordingly in the final rule.
    Guide suggested replacing the phrase ``same or symmetrically 
opposite design'' in Footnote 2 of Table XII of the NPRM with the 
phrase ``symmetrical beam pattern'' and also replacing the phrase 
``differing design'' in Footnote 3 of Table XII with the phrase 
``asymmetrical beam pattern'', claiming the terminology of the NPRM is 
vague. Guide offered no argument as to why the suggested replacement 
phrases would improve understanding. Since the language of the NPRM is 
faithful to the current version of FMVSS No. 108, we are not 
implementing its suggestion in the final rule.
    We have added the term ``Each Lamp'' after the title ``Two Lamp 
Systems'' in Table XII of the final rule to clarify that each lamp of a 
two lamp system is to be designed to conform to either the individual 
test point photometry requirements or the group photometry 
requirements.
Table XIII-a Motorcycle Turn Signal Lamp Alternative Photometry 
Requirements
Table XIII-b Motor Driven Cycle Stop Lamp Alternative Photometry 
Requirements
    Table XIII of the NPRM, License Plate Lamp Target Locations, has 
been redesignated as Figure 19 in the final rule. A new Table XIII has 
been created that includes the alternative stop lamp requirements for 
motor driven cycles, which were previously part of Table IX in the NPRM 
and the optional turn signal requirements for motorcycles noted in 
paragraphs S7.1.1.1 and S7.1.2.1 of the NPRM, but not previously 
tabularized.
Table XIV Parking Lamp Photometry Requirements
    There were no comments submitted that impacted Table XIV beyond 
those previously mentioned.
Table XV High-Mounted Stop Lamp Photometry Requirements
    AAM suggested that Footnote 4 of Table XV be incorporated directly 
into the table where the maximum photometric intensity is stated. AAM 
offered no arguments to support this request and we can see no 
compelling reason to implement it. Table XV appears in the final rule 
identical to the NPRM.
Table XVI
    As previously mentioned, Table XVI of the NPRM has been partitioned 
into three sections, Table XVI-a, Reflex Reflector Photometry 
Requirements, Table XVI-b, Additional Photometry Requirements for 
Conspicuity Reflex Reflectors, and Table XVI-c, Retroreflective 
Sheeting Photometry Requirements. The content of these tables in the 
final rule is identical to that of the NPRM.
Table XVII School Bus Signal Lamp Photometry
    There were no comments submitted that impacted Table XVII.
Table XVIII Headlamp Upper Beam Photometry Requirements
    There were no comments submitted that impacted Table XVIII beyond 
those previously mentioned.
Table XIX Headlamp Lower Beam Photometry Requirements
    Table XIX, Headlamp Lower Beam Photometry Requirements, has been 
split into Tables XIX-a, XIX-b, and XIX-c in the final rule.
    GE, Honda, AAM, and Koito identified that the maximum photometric 
intensity value of 2,500 cd for the 0.5D-1.5L to L test location of a 
LB4M beam was inadvertently omitted from Table XIX of the NPRM. We 
agree and this value has been added in the final rule.
    Guide suggested a reduction in the lateral limits in the NPRM for 
photometry of the 10[deg]U to 90[deg]U glare

[[Page 68263]]

area from 90[deg]L to 90[deg]R to 45[deg]L to 45[deg]R but offered no 
basis to support this request. Such a revision would be substantive and 
beyond the scope of the rewrite, therefore this suggestion was not 
pursued in the final rule.
Table XX Motorcycle and Motor Driven Cycle Headlamp Photometry 
Requirements
    Honda and Koito identified that the maximum photometric intensity 
value of 12,500 cd for the 4D-4R test location for a motor driven cycle 
headlamp was inadvertently placed in the minimum intensity column of 
Table XX of the NPRM. The value has been placed in the correct location 
in the final rule.
    AAM suggested that the column heading shown for lower beam 
headlamps be replicated for upper beam headlamps. We agree that doing 
so would improve clarity and have incorporated the headings in Table XX 
of the final rule.
Table XXI Associated Equipment Physical Test Requirements (Table 
eliminated in final rule)
    The recognition that the tabular method of organization did not 
work well for lengthy textual requirements provided the rationale for 
moving the associated equipment physical test requirements content of 
Table XXI of the NPRM to paragraph S14.9 of the regulatory text in the 
final rule.
    The substantive issues raised by public comment and the revisions 
to associated equipment physical test requirements are discussed under 
paragraph S14.9.
    Table XXII Lamp and Reflective Devices Physical Test Requirements 
(Table eliminated in final rule)
    The recognition that the tabular method of organization did not 
work well for lengthy textual requirements provided the rationale for 
moving the lamp and reflective devices physical test requirements 
content of Table XXII of the NPRM to paragraphs S14.3, S14.4, and S14.5 
of the regulatory text in the final rule.
    The substantive issues raised by public comment and the revisions 
to lamp and reflective devices physical test requirements are discussed 
under those sections.
Table XXIII Headlamp Physical Test Requirements (Table eliminated in 
final rule)
    The recognition that the tabular method of organization did not 
work well for lengthy textual requirements provided the rationale for 
moving the headlamp physical test requirements content of Table XXIII 
of the NPRM to paragraphs S14.6, S14.7, and S14.8 of the regulatory 
text in the final rule.
    The substantive issues raised by public comment and the revisions 
to headlamp physical test requirements are discussed under those 
sections.
Figures
Figures 1 through 12 and 15 through 18
    There were no comments submitted that impacted Figures 1 through 12 
or Figures 15 through 18.
Figure 13 Tractor Conspicuity Treatment Examples
    TMA commented that Figure 31 of the current version of FMVSS No. 
108, rather than Figure 13 of the NPRM, better illustrated that the 
right angle white conspicuity treatment element required on the upper 
rear outside corners of truck tractors may not be continuous if cab 
mounted hardware makes this impractical. We have revised Figure 13 to 
illustrate this condition in the final rule.
Figure 14 92 x 150 mm Headlamp Aim Deflection Test Setup
    GE identified 13 omissions or errors in Figure 14 of the NPRM that 
were corrected in the final rule to agree with the source document, 
Figure 16 of the current version of FMVSS No. 108.
Figure 15 Types G & H Headlamp Aim Deflection Test Setup
    GE identified an omission in Figure 15 that was corrected to agree 
with the source document, Figure 22 of the current version of FMVSS No. 
108.
Figure 19 License Plate Lamp Target Locations
    Figure 19, License Plate Lamp Target Locations, was designated as 
Table XIII in the NPRM. The supplementary response from the AAM/ASSN 
suggested changing it to be a figure. Its purpose is illustrative, so 
it is most appropriately designated as a figure.
    AAM requested that the English units of measurement, which were 
part of the source drawings, SAE J587 OCT81 Figures 1 and 2, but not 
included in Table XIII of the NPRM, be restored. This was done, as 
Figure 19 is dimensioned in both metric and English units in the final 
rule.
Figure 20 License Plate Lamp Measurement of Incident Light Angle
    AAM requested that Figure 3 of SAE J587 OCT81, License Plate Lamps, 
be included to better illustrate the incident light angle requirement 
of paragraph S7.7.1.1 of the NPRM. We agree and have included it as 
Figure 20, License Plate Lamp Measurement of Incident Light Angle, in 
the final rule. It is referenced in paragraph S7.7.15.4 of the final 
rule.
Figure 21 Vibration Test Machine
    AAM requested that SAE J577, Vibration Test Machine, April 1964, be 
directly incorporated into FMVSS No. 108 rather than to continue to be 
incorporated by reference. Figure 1, Vibration Test Machine, and Table 
1, Cam Profile Radii, (from SAE J577) were redrawn for the final rule 
as Figure 21, Vibration Test Machine.
Figure 22 Flasher Standard Test Circuit
    Figure 22 includes the standard test circuit of SAE J823b, Flasher 
Test Equipment, April 1968. The procedures of SAE J823b have also been 
incorporated into paragraph S14.9 of the final rule, allowing the 
subreference by incorporation of this standard to now be eliminated 
from FMVSS No. 108.

IV. The Final Rule

    After careful consideration of public comments on the NPRM, the 
agency has decided to publish a final rule to amend 49 CFR Part 564 and 
FMVSS No. 108 as discussed below:

A. 49 CFR Part 564

    We are relocating figures addressing sealed beam headlamps that 
currently reside in FMVSS No. 108 and SAE J1383 APR85 into a newly 
created Appendix C of 49 CFR Part 564. We have listed those specific 
figures and where they currently reside in FMVSS No. 108 or SAE J1383 
APR85 in the reference document in Appendix C of this notice. In 
addition, we are making the applicable changes to the scope and purpose 
provisions of Part 564 to account for the newly formed Appendix C. 
Unlike Appendices A and B, there will be no further additions to, or 
modifications of, the sealed beam headlamp figures in Appendix C.

B. 49 CFR Part 571.108

    We are amending Standard No. 108 by: (1) Reorganizing the 
regulatory text so that it provides a more straight-forward and logical 
presentation of the applicable regulatory requirements; (2) including 
important agency interpretations of the existing requirements; and (3) 
reducing reliance on third-party documents incorporated by reference. 
This has resulted in additional tables and figures being added to the 
standard. In addition, the structure of the standard has been changed 
to present the requirements in a more standardized and user-friendly 
manner.

[[Page 68264]]

V. Benefits and Costs

    Because this proposal only reorganizes the existing requirements of 
the standard, we do not anticipate that there would be any costs or 
benefits associated with this rulemaking action to implement an 
administrative rewrite of FMVSS No. 108, other than the benefits 
associated with a clearer, easier-to-read standard. None of the public 
comments identified any instances where the rewritten standard would 
have a cost effect. Accordingly, the agency did not conduct a separate 
economic analysis for this rulemaking.

VI. Rulemaking Analyses and Notices

A. Vehicle Safety Act

    Under 49 U.S.C. Chapter 301, Motor Vehicle Safety (49 U.S.C. 30101 
et seq.), the Secretary of Transportation is responsible for 
prescribing motor vehicle safety standards that are practicable, meet 
the need for motor vehicle safety, and are stated in objective 
terms.\35\ These motor vehicle safety standards set the minimum level 
of performance for a motor vehicle or motor vehicle equipment to be 
considered safe.\36\ When prescribing such standards, the Secretary 
must consider all relevant, available motor vehicle safety 
information.\37\ The Secretary must also consider whether a proposed 
standard is reasonable, practicable, and appropriate for the type of 
motor vehicle or motor vehicle equipment for which it is prescribed and 
the extent to which the standard will further the statutory purpose of 
reducing traffic accidents and associated deaths.\38\ The 
responsibility for promulgation of Federal motor vehicle safety 
standards has been delegated to NHTSA. \39\
---------------------------------------------------------------------------

    \35\ 49 U.S.C. 30111(a).
    \36\ 49 U.S.C. 30102(a)(9).
    \37\ 49 U.S.C. 30111(b).
    \38\ Id.
    \39\ 49 U.S.C. 105 and 322; delegation of authority at 49 CFR 
1.50.
---------------------------------------------------------------------------

    FMVSS No. 108, Lamps, Reflective Devices, and Associated Equipment, 
was originally established in a final rule published in the Federal 
Register on February 3, 1967 (32 FR 2408). The purpose of the standard 
is to reduce traffic accidents and deaths and injuries resulting from 
traffic accidents, by providing adequate illumination of the roadway, 
and by enhancing the conspicuity of motor vehicles on the public roads 
so that their presence is perceived and their signals understood, both 
in daylight and in darkness or other conditions of reduced visibility. 
Since the time of the standard's initial promulgation, the agency has 
undertaken numerous rulemakings and interpretations related to Standard 
No. 108, in many cases to deal with the emergence of new lighting 
technologies. In recent years, concerns have been raised that after 
nearly four decades of amendment, navigating the requirements of the 
standard has become increasingly difficult. Therefore, in this final 
rule, the agency is implementing an administrative rewrite of Standard 
No. 108 in order to improve its structure and clarity, without changing 
any of its existing substantive requirements. In preparing this final 
rule, the agency carefully considered the statutory requirements of 49 
U.S.C. Chapter 301.
    First, this final rule reflects the agency's careful consideration 
and analysis of all existing regulatory provisions of FMVSS No. 108, as 
well as salient letters of interpretation related to that standard. In 
developing the substantive provisions of the standard over the years, 
the agency considered all relevant, available motor vehicle safety 
information, including available research, testing results, and other 
information related to various technologies. This administrative 
rewrite does not change any of these existing provisions or the 
underlying basis therefore. The final rule also reflects the agency's 
consideration of information offered in public comments on the notice 
of proposed rulemaking which preceded today's final rule.
    Second, to ensure that the requirements of FMVSS No. 108 are 
practicable (as well as consistent with our safety objectives), the 
agency evaluated the cost, availability, and suitability of the 
standard's provisions, both when initially adopted and during 
subsequent amendments. As noted above, the changes resulting from this 
final rule are administrative in nature and would not impact the costs 
and benefits of the standard. In sum, we believe that this final rule 
is practicable, and we expect it to maintain the benefits of Standard 
No. 108.
    Third, the regulatory text following this preamble is stated in 
objective terms in order to specify precisely what performance is 
required and how performance will be tested to ensure compliance with 
the standard. In certain cases, the final rule modifies the language of 
the standard to improve clarity or to incorporate existing 
interpretations, again without changing the substance of the existing 
requirements.
    Fourth, we believe that this final rule meets the need for motor 
vehicle safety by clarifying the safety standard, thereby making it 
easier for regulated parties to comply with all applicable 
requirements. The impacts of the substantive provisions on vehicle 
safety were discussed at the time of adoption of those provisions.
    Finally, we believe that this final rule is reasonable and 
appropriate for motor vehicles subject to the applicable requirements. 
As discussed elsewhere in this notice, the modifications to the 
standard resulting from this final rule are administrative in nature. 
It does not affect the substance of the requirements or the bases for 
those requirements, as articulated in earlier rulemakings. Accordingly, 
we believe that this final rule is appropriate for covered vehicles 
that are or become subject to these provisions of FMVSS No. 108 because 
it furthers the agency's objective of preventing crash-related deaths 
and serious injuries by ensuring adequate illumination of roadways and 
enhanced conspicuity of motor vehicles.

B. Executive Order 12866 and DOT Regulatory Policies and Procedures

    Executive Order 12866, ``Regulatory Planning and Review'', provides 
for making determinations whether a regulatory action is 
``significant'' and therefore subject to OMB review and to the 
requirements of the Executive Order. The Order defines a ``significant 
regulatory action'' as one that is likely to result in a rule that may:
    (1) Have an annual effect on the economy of $100 million or more or 
adversely affect in a material way the economy, a sector of the 
economy, productivity, competition, jobs, the environment, public 
health or safety, or State, local, or Tribal governments or 
communities;
    (2) Create a serious inconsistency or otherwise interfere with an 
action taken or planned by another agency;
    (3) Materially alter the budgetary impact of entitlements, grants, 
user fees, or loan programs or the rights and obligations of recipients 
thereof; or
    (4) Raise novel legal or policy issues arising out of legal 
mandates, the President's priorities, or the principles set forth in 
the Executive Order.
    This rulemaking document was not reviewed by the Office of 
Management and Budget under Executive Order 12866. The rule is not 
considered to be significant within the meaning of E.O. 12866 or the 
Department of Transportation's Regulatory Policies and Procedures (44 
FR 11034 (Feb. 26, 1979)). As stated above in Section V, Benefits and 
Costs, this final rule is not expected to require parties subject to 
the requirements of the safety standard to alter their existing 
practices for certifying compliance with Standard

[[Page 68265]]

No. 108 or to increase costs of compliance, because the final rule 
merely reorganizes and clarifies existing requirements. Accordingly, 
the agency has not prepared any supplemental economic analysis to 
accompany this rulemaking document.

C. Regulatory Flexibility Act

    Pursuant to the Regulatory Flexibility Act (5 U.S.C. 601 et seq., 
as amended by the Small Business Regulatory Enforcement Fairness Act 
(SBREFA) of 1996), whenever an agency is required to publish a notice 
of rulemaking for any proposed or final rule, it must prepare and make 
available for public comment a regulatory flexibility analysis that 
describes the effect of the rule on small entities (i.e., small 
businesses, small organizations, and small governmental jurisdictions). 
The Small Business Administration's regulations at 13 CFR Part 121 
define a small business, in part, as a business entity ``which operates 
primarily within the United States.'' (13 CFR 121.105(a)). No 
regulatory flexibility analysis is required if the head of an agency 
certifies the rule will not have a significant economic impact on a 
substantial number of small entities. SBREFA amended the Regulatory 
Flexibility Act to require Federal agencies to provide a statement of 
the factual basis for certifying that a rule will not have a 
significant economic impact on a substantial number of small entities.
    NHTSA has considered the effects of this final rule under the 
Regulatory Flexibility Act. I certify that this final rule will not 
have a significant economic impact on a substantial number of small 
entities. The rationale for this certification is that the present 
final rule does not make any substantive changes to this safety 
standard, so affected parties will be able to continue current 
practices without change. Accordingly, we do not anticipate that this 
final rule will have a significant economic impact on a substantial 
number of small entities.

D. Executive Order 13132 (Federalism)

    NHTSA has examined today's final rule pursuant to Executive Order 
13132, ``Federalism'' and concluded that no additional consultation 
with States, local governments, or their representatives is mandated 
beyond the rulemaking process. The agency has concluded that the rule 
does not have Federalism implications, because the rule does not have 
``substantial direct effects on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and the responsibilities among the various levels of government.''
    Further, no consultation is needed to discuss the preemptive effect 
of today's rule. NHTSA rules can have preemptive effect in at least two 
ways. First, the National Traffic and Motor Vehicle Safety Act contains 
an express preemptive provision: ``When a motor vehicle safety standard 
is in effect under this chapter, a State or a political subdivision of 
a State may prescribe or continue in effect a standard applicable to 
the same aspect of performance of a motor vehicle or motor vehicle 
equipment only if the standard is identical to the standard prescribed 
under this chapter.'' 49 U.S.C. 30102(b)(1).
    In addition to the express preemption noted above, the Supreme 
Court has also recognized that State requirements imposed on motor 
vehicle manufacturers, including sanctions imposed by State tort law, 
can stand as an obstacle to the accomplishment and execution of a NHTSA 
safety standard. When such a conflict is discerned, the Supremacy 
Clause of the Constitution makes the State requirements unenforceable. 
See Geier v. American Honda Motor Co., 529 U.S. 861 (2000).
    NHTSA does not believe that such conflicts are likely to arise from 
today's rulemaking, because this final rule only results in an 
administrative rewrite of the existing requirements of FMVSS No. 108. 
However, if such a conflict were to become evident, NHTSA may opine on 
such conflicts in the future, if warranted. See id. at 883-86.

E. Executive Order 12988 (Civil Justice Reform)

    With respect to the review of the promulgation of a new regulation, 
section 3(b) of Executive Order 12988, ``Civil Justice Reform,'' 
requires that Executive agencies make every reasonable effort to ensure 
that the regulation: (1) Clearly specifies the preemptive effect; (2) 
clearly specifies the effect on existing Federal law or regulation; (3) 
provides a clear legal standard for affected conduct, while promoting 
simplification and burden reduction; (4) clearly specifies the 
retroactive effect, if any; (5) adequately defines key terms; and (6) 
addresses other important issues affecting clarity and general 
draftsmanship under guidelines issued by the Attorney General. This 
document is consistent with that requirement. Pursuant to this Order, 
NHTSA notes as follows. The preemptive effect of this rule is discussed 
above. NHTSA notes further that there is no requirement that 
individuals submit a petition for reconsideration or pursue other 
administrative proceeding before filing suit in court.

F. Executive Order 13045 (Protection of Children From Environmental 
Health and Safety Risks)

    Executive Order 13045, ``Protection of Children from Environmental 
Health and Safety Risks,'' applies to any rule that: (1) Is determined 
to be ``economically significant'' as defined under Executive Order 
12866, and (2) concerns an environmental, health, or safety risk that 
the agency has reason to believe may have a disproportionate effect on 
children. If the regulatory action meets both criteria, the agency must 
evaluate the environmental health or safety effects of the planned rule 
on children, and explain why the planned regulation is preferable to 
other potentially effective and reasonably feasible alternatives 
considered by the agency.
    This final rule is not subject to E.O. 13045 because it is not an 
economically significant regulatory action under Executive Order 12866, 
and because it does not involve decisions based upon health and safety 
risks that disproportionately affect children.

G. Paperwork Reduction Act

    Under the Paperwork Reduction Act of 1995 (PRA), a person is not 
required to respond to a collection of information by a Federal agency 
unless the collection displays a valid OMB control number. This final 
rule does not contain any collection of information requirements 
requiring review under the PRA.

H. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (NTTAA), Public Law 104-113, (15 U.S.C. 272) directs the 
agency to evaluate and use voluntary consensus standards in its 
regulatory activities unless doing so would be inconsistent with 
applicable law or is otherwise impractical. Voluntary consensus 
standards are technical standards (e.g., materials specifications, test 
methods, sampling procedures, and business practices) that are 
developed or adopted by voluntary consensus standards bodies, such as 
the Society of Automotive Engineers. The NTTAA directs us to provide 
Congress (through OMB) with explanations when we decide not to use 
available and applicable voluntary consensus standards. The NTTAA does 
not apply to symbols.

[[Page 68266]]

    This final rule does not adopt or reference any new industry or 
consensus standards that were not already present in Standard No. 108 
(although in several cases, relevant requirements from such standards 
are now included directly in the standard, rather than being 
incorporated by reference). The agency's statements regarding the 
rationale for the use (or non-use) of information from third-party 
standards, as presented in prior rulemakings, remain unchanged.

I. Unfunded Mandates Reform Act

    Section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA) 
requires Federal agencies to prepare a written assessment of the costs, 
benefits, and other effects of proposed or final rules that include a 
Federal mandate likely to result in the expenditure by State, local, or 
tribal governments, in the aggregate, or by the private sector, of more 
than $100 million annually (adjusted for inflation with base year of 
1995 (so currently $126 million in 2006 dollars)). Before promulgating 
a NHTSA rule for which a written statement is needed, section 205 of 
the UMRA generally requires the agency to identify and consider a 
reasonable number of regulatory alternatives and adopt the least 
costly, most cost-effective, or least burdensome alternative that 
achieves the objectives of the rule. The provisions of section 205 do 
not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows the agency to adopt an alternative other than the 
least costly, most cost-effective, or least burdensome alternative if 
the agency publishes with the final rule an explanation of why that 
alternative was not adopted.
    This final rule is not anticipated to result in the expenditure by 
State, local, or tribal governments, in the aggregate, or by the 
private sector in excess of $112 million annually. Instead, the cost 
impact of this administrative rewrite of Standard No. 108 is expected 
to be $0, because it does not change or increase the cost of existing 
requirements. Therefore, the agency has not prepared an economic 
assessment pursuant to the Unfunded Mandates Reform Act.

J. National Environmental Policy Act

    NHTSA has analyzed this rulemaking action for the purposes of the 
National Environmental Policy Act. The agency has determined that 
implementation of this action would not have any significant impact on 
the quality of the human environment.

K. Regulatory Identifier Number (RIN)

    The Department of Transportation assigns a regulation identifier 
number (RIN) to each regulatory action listed in the Unified Agenda of 
Federal Regulations. The Regulatory Information Service Center 
publishes the Unified Agenda in April and October of each year. You may 
use the RIN contained in the heading at the beginning of this document 
to find this action in the Unified Agenda.

    Direct reading indicator means a device that is mounted in its 
entirety on a headlamp or headlamp aiming or headlamp mounting 
equipment, is part of a VHAD, and provides information about headlamp 
aim in an analog or digital format.
    Effective light-emitting surface means that portion of a lamp that 
directs light to the photometric test pattern, and does not include 
transparent lenses, mounting hole bosses, reflex reflector area, beads 
or rims that may glow or produce small areas of increased intensity as 
a result of uncontrolled light from an area of \1/2\[deg] radius around 
a test point.
    Effective projected luminous lens area means the area of the 
orthogonal projection of the effective light-emitting surface of a lamp 
on a plane perpendicular to a defined direction relative to the axis of 
reference. Unless otherwise specified, the direction is coincident with

associated equipment, including a combination lamp, must:
    (a) Be designed to conform to meet all requirements specified in 
this standard for that type of lamp, reflective device, or other item 
of equipment (in the case of a combination lamp, it must meet these 
requirements for each function); and
    (b) Include all of the functions of the lamp, reflective device, or 
item of associated equipment, including a combination lamp, it is 
designed to replace or is capable of replacing (other than functions 
not required by this standard).
    S6.7.1.2 Each replacement lamp, reflective device, or item of 
associated equipment, including a combination lamp, which is designed 
or recommended for particular vehicle models must be designed so that 
it does not take the vehicle out of compliance with this standard when 
the individual device is installed on the vehicle. Except as provided 
in S6.7.1.3, the determination of whether a vehicle would be taken out 
of compliance with this standard when an individual device is installed 
on the vehicle is made without regard to whether additional devices, 
including separate lamps or reflective devices sold together with the 
device, would also be installed.
    S6.7.1.3 In the case of a lamp or other device that is used on each 
side of the vehicle in pairs, the determination (for the purposes of 
S6.7.1.2) of whether a vehicle would be taken out of compliance with 
this standard when an individual device is installed on the vehicle is 
made assuming that the other matched paired device would be installed 
on the other side of the vehicle, whether or not the matched paired 
devices are sold together. This provision does not limit the 
responsibilities of manufacturers, distributors, dealers or motor 
vehicle repair businesses under 49 U.S.C. 30122, Making safety devices 
and elements inoperative.
    S6.7.2 Version of this standard. The requirements of S6.7.1 must be

the headlamp.
    S10.18.6 Moveable reflectors. Each headlamp aimed by moving the 
reflector relative to the lens and headlamp housing, or vice versa, 
must conform with the photometric requirements applicable to it when 
tested according to the procedure of S14.2.5 with the lens at any 
position relative to the reflector within the full range of vertical 
pitch on the vehicle on which the headlamp system is installed and a 
horizontal range of  2.5[deg]. Additionally it must comply 
with the aiming adjustment requirements of S14.6.
    S10.18.7 External aiming. Each headlighting system that is capable 
of being mechanically aimed by externally applied headlamp aiming 
devices must be mechanically aimable using the equipment specified in 
SAE J602 Headlamp Aiming Device for Mechanically Aimable Sealed Beam 
Headlamp Units, October 1980, (incorporated by reference, see 571.108 
S5.2 of this title) without the removal of any ornamental trim rings, 
covers, wipers or other vehicle parts.
    S10.18.7.1 Headlamp aiming device locating plates. Each 
headlighting system which is designed to use the Headlamp Aiming Device 
Locating Plates with adjustable legs for the 100x165 mm unit and the 
142x200 mm unit, and which has adjustable length legs, must meet the 
following requirements:
    S10.18.7.1.1 The lens must have three aiming pads which meet the 
requirements of Figure 4, Dimensional Specifications for Location of 
Aiming Pads on Replaceable Bulb Headlamp Units. The aiming pads need 
not be centered at the geometric center of the lens, or on the optical 
axis. Except as provided in S10.18.7.1.2, a whole number, which 
represents the distance in tenths of an inch (i.e. 0.3 inch = 3) from 
the aiming reference plane to the respective aiming pads which are not 
in contact with that plane, must be inscribed adjacent to each 
respective aiming pad on the lens. The height of these numbers must be 
not less than .157 inch (4 mm). If there is interference between the 
plane and the area of the lens between the aiming pads, the whole 
number represents the distance to a secondary plane. The secondary 
plane must be located parallel to the aiming reference plane and as 
close to the lens as possible without causing interference.
    S10.18.7.1.2 If the most forward aiming pad is the lower inboard

146 mm diameter unit, or the 178 mm diameter unit of SAE J602 OCT80, 
Headlamp Aiming Device for Mechanically Aimable Sealed Beam Headlamp 
Units, (incorporated by reference, see 571.108 S5.2 of this title), or 
the 92x150 mm Type F unit, and incorporate lens-mounted aiming pads as 
specified for those units pursuant to Appendix C of part 564 of this 
chapter. If so designed, no additional lens marking is necessary to 
designate the type of plate or dimensions.
    S10.18.8 On-vehicle aiming. Each headlighting system that is 
capable of being aimed by equipment installed on the vehicle must 
include a Vehicle Headlamp Aiming Device (VHAD) that conforms to the 
following requirements:
    S10.18.8.1 Aim. The VHAD must provide for headlamp aim inspection 
and adjustment in both the vertical and horizontal axes.
    S10.18.8.1.1 Vertical aim. The VHAD must include the necessary 
references and scales relative to the horizontal plane to assure 
correct vertical aim for photometry and aiming purposes. An off vehicle 
measurement of the angle of the plane of the ground is permitted. In 
addition, an equal number of graduations from the ``0'' position 
representing angular changes in the axis in the upward and downward 
directions must be provided.
    S10.18.8.1.1.1 Each graduation must represent a change in the 
vertical position of the mechanical axis not larger than 0.19[deg] (1

and below the horizontal, and have an accuracy relative to the zero 
mark of less than 0.1[deg].
    S10.18.8.1.1.2 The VHAD must be marked to indicate headlamp aim 
movement in the upward and downward directions.
    S10.18.8.1.1.3 Each graduation must indicate a linear movement of 
the scale indicator of not less than 0.05 in (1.27 mm) if a direct 
reading analog indicator is used. If a remote reading indicator is 
provided, it must represent the actual aim movement in a clear, 
understandable format.
    S10.18.8.1.1.4 The vertical indicator must perform through a 
minimum range of  1.2[deg].
    S10.18.8.1.1.5 Means must be provided in the VHAD for compensating 
for deviations in floor slope less than 1.2[deg] from the horizontal 
that would affect the correct positioning of the headlamp for vertical 
aim.
    S10.18.8.1.1.6 The graduations must be legible under an 
illumination level not greater than 30 foot candles, measured at the 
top of the graduation, by an observer having 20/20 vision (Snellen),

top of the graduation, by an observer having 20/20 vision (Snellen), 
and must permit aim adjustment to within 0.38[deg] (2 in at 25 ft).
    S10.18.8.1.2.4 The horizontal indicator must perform through a 
minimum range of  0.76[deg] (4 in at 25 ft); however, the 
indicator itself must be capable of recalibration over a movement of 
 2.5[deg] relative to the longitudinal axis of the vehicle 
to accommodate any adjustment necessary for recalibrating the indicator 
after vehicle repair from accident damage.
    S10.18.8.2 Aiming instructions.
    S10.18.8.2.1 The instructions for properly aiming the headlighting 
system using the VHAD must be provided on a label permanently affixed 
to the vehicle adjacent to the VHAD, or in the vehicle operator's 
manual. The instructions must advise that the headlighting system is 
properly aimed if the appropriate vertical plane (as defined by the 
vehicle manufacturer) is perpendicular to both the longitudinal axis of 
the vehicle, and a horizontal plane when the vehicle is on a horizontal 
surface, and the VHAD is set at ``0'' vertical and ``0'' horizontal.
    S10.18.8.2.2 Should a remote indicator or a remote indicator and 
adjuster be provided, the instructions must be placed in the operator's 
manual, and may also be placed on a label adjacent to the VHAD.
    S10.18.8.3 Permanent calibration. Each headlamp equipped with a 
VHAD must be manufactured with its calibration permanently fixed by its 
manufacturer. Calibration in this case means the process of accurately 
aligning the geometry of the VHAD devices with the beam pattern for the 
purposes of compliance with the standard.
    S10.18.8.4 Replacement units. When tested according to the 
procedure of S14.2.5 with any replacement headlamp unit(s) or light 
sources intended for use in the system under test, the VHAD and 
headlighting system must be designed to conform to the photometric 
performance requirements applicable for the system under test.
    S10.18.8.5 Physical tests. Each VHAD must be designed to conform 
with the performance requirements of S14.8.
    S10.18.9 Visual/optical aiming. Each visually/optically aimable 
headlamp must be designed to conform to the following requirements:
    S10.18.9.1 Vertical aim, lower beam. Each lower beam headlamp must 
have a cutoff in the beam pattern. It may be either on the left side or 
the right side of the optical axis, but once chosen for a particular 
headlamp system's design, the side chosen for the cutoff must not be 
changed for any headlamps intended to be used as replacements for those 
system's headlamps.
    S10.18.9.1.1 Vertical position of the cutoff. The headlamp must be 
aimed vertically so that the cutoff is on the left side, at 0.4[deg] 
down from the H-H line, or on the right side, at the H-H line.
    S10.18.9.1.2 Vertical gradient. The gradient of the cutoff measured 
at either 2.5[deg] L or 2.0[deg] R must be not less than 0.13 based on 
the procedure of S10.18.9.1.5.
    S10.18.9.1.3 Horizontal position of the cutoff. The width must be 
not less than 2[deg], with not less than 2[deg] of its actual width 
centered at either 2.5[deg] L, or 2.0[deg] R.
    S10.18.9.1.4 Maximum inclination of the cutoff. The vertical 
location of the highest gradient at the ends of the minimum width must 
be within  0.2[deg] of the vertical location of the maximum 
gradient measured at the appropriate vertical line (at either 2.5[deg] 
L for a left side cutoff, or 2.0[deg] R for a right side cutoff).
    S10.18.9.1.5 Measuring the cutoff parameter.
    S10.18.9.1.5.1 The headlamp is mounted on a headlamp test fixture 
which simulates its actual design location on any vehicle for which the 
headlamp is intended. The fixture, with the headlamp installed, is 
attached to the goniometer table in such a way that the fixture 
alignment axes are coincident with the goniometer axes. The headlamp is 
energized at the specified test voltage. The cutoff parameter must be 
measured at a distance of 10 m from a photosensor with a 10 mm 
diameter.
    S10.18.9.1.5.2 The headlamp beam pattern is aimed with the cutoff 
at the H-H axis. There is no adjustment, shimming, or modification of 
the horizontal axis of the headlamp or test fixture, unless the 
headlamp is equipped with a VHAD. In this case the VHAD is adjusted to 
zero.
    S10.18.9.1.5.3 A vertical scan of the beam pattern is conducted for 
a headlamp with a left side gradient by aligning the goniometer on a 
vertical line at 2.5[deg] L and scanning from 1.5[deg] U to 1.5[deg] D. 
For a headlamp with a right side gradient, a vertical scan of the beam 
pattern is conducted by aligning the goniometer on a vertical line at 
2.0[deg] R and scanning from 1.5[deg] U to 1.5[deg] D.
    S10.18.9.1.5.4 Determine the maximum gradient within the range of 
the scan by using the formula: G = log E(a)-logE(a + 0.1), where ``G'' 
is the gradient, ``E'' is illumination and ``a'' is vertical angular 
position. The maximum value of the gradient ``G'' determines the 
vertical angular location of the cutoff. Perform vertical scans at 
1.0[deg] L and R of the measurement point of the maximum gradient to 
determine the inclination.
    S10.18.9.2 Horizontal aim, lower beam. There is no adjustment of 
horizontal aim unless the headlamp is equipped with a horizontal VHAD. 
If the headlamp has a VHAD, it is set to zero.
    S10.18.9.3 Vertical aim, upper beam.
    S10.18.9.3.1 If the upper beam is combined in a headlamp with a 
lower beam, the vertical aim of the upper beam must not be changed from 
the aim set using the procedures of S10.18.9.1 and S10.18.9.2 used for 
the lower beam.
    S10.18.9.3.2 If the upper beam is not combined in a headlamp with a 
lower beam, the vertical aim of the upper beam is adjusted so that the 
maximum beam intensity is located on the H-H axis.
    S10.18.9.4 Horizontal aim, upper beam.
    S10.18.9.4.1 If the upper beam is combined in a headlamp with a 
lower beam, the horizontal aim of the upper beam must not be changed 
from the aim set using the procedures of S10.18.9.1 and S10.18.9.2 used 
for the lower beam.
    S10.18.9.4.2 If the upper beam is not combined in a headlamp with 
the lower beam and has fixed horizontal aim or has a horizontal VHAD, 
then the headlamp is mounted on a headlamp test fixture which simulates 
its actual design location on any vehicle for which the headlamp is 
intended. The fixture, with the headlamp installed, is attached to the 
goniometer table in such a way that the fixture alignment axes are

[[Page 68287]]

coincident with the goniometer axes. The headlamp must be energized at 
12.8  0.20 mV. There is no adjustment, shimming, or 
modification of the horizontal axis of the headlamp or test fixture, 
unless the headlamp is equipped with a VHAD. In this case the VHAD is 
adjusted to zero.
    S10.18.9.4.3 If the upper beam is not combined in a headlamp with a 
lower beam, and it does not have a VHAD, the horizontal aim of the 
upper beam is adjusted so that the maximum beam intensity is located on 
the V-V axis.
    S10.18.9.5 Photometry. When tested according to the procedure of 
S14.2.5, a visually/optically aimable headlamp must be designed to 
conform to the lower beam requirements of columns; LB1V or LB2V of 
Table XIX-a, or LB3V of Table XIX-b, or LB4V of Table XIX-c.
    S10.18.9.6 Visual/optical aiming identification marking. Each 
letter used in marking according to this paragraph must be not less 
than 3 mm high.
    S10.18.9.6.1 The lens of a lower beam headlamp must be marked 
``VOL'' if the headlamp is intended to be visually/optically aimed 
using the left side of the lower beam pattern. The lens of a lower beam 
headlamp must be marked ``VOR'' if the headlamp is intended to be 
visually/optically aimed using the right side of the lower beam 
pattern. The lens of a headlamp that is solely an upper beam headlamp 
and intended to be visually/optically aimed using the upper beam must 
be marked ``VO''.
    S10.18.9.6.2 The lens of each sealed beam or integral beam headlamp 
must be marked ``VOR'' if the headlamp is of a type that was 
manufactured before May 1, 1997, and if such headlamp type has been 
redesigned since then to be visually/optically aimable.
    S11 Replaceable light source requirements. Each replaceable light 
source must be designed to conform to the dimensions and electrical 
specifications furnished with respect to it pursuant to part 564 of 
this chapter, on file in Docket No. NHTSA 98-3397, and must conform to

    S14.2.3.1 Mounting. Each reflex reflector is mounted for photometry

[[Page 68289]]

with the center of the reflex area at the center of goniometer rotation 
and at the same horizontal level as the source of illumination.
    S14.2.3.2 Illumination source. The source of illumination is a lamp 
with a 50 mm effective diameter and with a filament operating at 2856 
[deg]K.
    S14.2.3.3 Measurement distance. The test distance is 30.5 m 
[100ft].
    S14.2.3.4 Test setup The observation point is located directly 
above the source of illumination. The H-V axis of reflex reflectors is 
taken as parallel to the longitudinal axis of the vehicle for rear 
reflectors and perpendicular to a vertical plane passing through the 
longitudinal axis of the vehicle for side reflectors.
    S14.2.3.5 Photodetector. The photodetector has an opening of not 
more than 13 mm vertically and 25 mm horizontally.
    S14.2.3.6 Photometry surface. Reflex reflectors may have any linear 
or area dimensions but must have no more than 7740 sq mm projected area 
contained within a 254 mm diameter circle exposed for photometry.
    S14.2.3.7 Procedure. Photometric measurements of reflex reflectors 
and retroreflective sheeting must be made at various observation and 
entrance angles as shown in Table XVI.
    S14.2.3.7.1 The observation angle is the angle formed by a line 
from the observation point to the center of the reflector and a second 
line from the center of the reflector to the source of illumination.
    S14.2.3.7.2 The entrance angle is the angle between the axis of the 
reflex reflector and a line from the center of the reflector to the 
source of illumination.
    S14.2.3.7.3 The entrance angle is designated left, right, up, and 
down in accordance with the position of the source of illumination with 
respect to the axis of the reflex reflector as viewed from behind the 
reflector.
    S14.2.3.7.4 Measurements are made of the luminous intensity which 
the reflex reflector is projecting toward the observation point and the 
illumination on the reflex reflector from the source of illumination.
    S14.2.3.8 Measurements.
    S14.2.3.8.1 Reflex reflectors. The required measurement for reflex 
reflectors at each test point as shown in Table XVI is the quotient of 
the projected luminous intensity divided by the illumination expressed 
as millicandela per lux or candela per footcandle.
    S14.2.3.8.2 Retroreflective sheeting. The required measurement for 
retroreflective sheeting reflectors at each test point as shown in 
Table XVI is candela per lux per square meter of area.
    S14.2.3.8.3 Reflex reflector photometry measurement adjustments.
    S14.2.3.8.3.1 Reflex reflectors, which do not have a fixed 
rotational position on the vehicle, are rotated about their axis 
through 360[deg] to find the minimum photometric value which must be 
reported for each test point. If the output falls below the minimum 
requirement at any test point, the reflector is rotated < plus-
minus>5[deg] about its axis from the angle where the minimum output 
occurred, and the maximum value within this angle is reported as a 
tolerance value.
    S14.2.3.8.3.2 Reflex reflectors, which by their design or 
construction, permit mounting on a vehicle in a fixed rotational 
position, are tested in this position. A visual locator, such as the 
word TOP is not considered adequate to establish a fixed rotational 
position on the vehicle.
    S14.2.3.8.3.3 If uncolored reflections from the front surface 
interfere with photometric readings at any test point, additional 
readings are taken 1[deg] above, below, right, and left of the test 
point, and the lowest of these readings and its location is reported 
provided the minimum test point requirement for the test point is met.
    S14.2.4 Daytime running lamp (DRL) photometry measurements.
    S14.2.4.1 Each DRL is tested to the procedure of S14.2.5 when a 
test voltage of 12.8 v  20 mv is applied to the input 
terminals of the lamp switch module or voltage-reducing equipment, 
whichever is closer to the electrical source on the vehicle.
    S14.2.4.2 The test distance from the lamp to the photometer is not 
less than 18.3 m if the lamp is optically combined with a headlamp, or 
is a separate lamp, and not less than 3 m if the lamp is optically 
combined with a lamp, other than a headlamp, that is required by this 
standard.
    S14.2.4.3 Bulb requirements of S14.2.1.6 apply to DRL photometry.
    S14.2.5 Headlamp photometry measurements.
    S14.2.5.1 Mounting. Photometry measurements at the applicable test 
points are made with the sample headlamp mounted in its normal 
operating position.
    S14.2.5.2 Test points in the area from 10[deg] U to 90[deg] U must 
be measured from the normally exposed surface of the lens face.
    S14.2.5.3 Measurement distance. Photometric measurements are made 
at a distance between the light source and the photometer sensor of at 
least 18.3 m.
    S14.2.5.4 Seasoning and test voltage. All sealed beam headlamps, 
integral beam headlamps, beam contributors, and replaceable light 
sources are seasoned at design voltage for 1% of its average design 
life or 10 hours, whichever is less prior to a photometry test. A 
headlamp is tested at 12.8 v.  20 mv, D.C. as measured at 
the terminals of the lamp.
    S14.2.5.5 Aiming. Each headlamp is aimed prior to a photometry test 
in accordance with the procedure appropriate to its aiming system. A 
\1/4\[deg] reaim is permitted in any direction at any test point to 
allow for variations in readings between laboratories for all headlamps 
except a Type F upper beam unit not equipped with a VHAD.
    S14.2.5.5.1 Mechanically aimable headlamps using an external aimer. 
The headlamp is aimed mechanically with the aiming plane at the design 
angle(s) to the photometer axis and the mechanical axis of the headlamp 
on the photometer axis.
    S14.2.5.5.2 Mechanically aimable headlamps equipped with a VHAD. 
The headlamp is aimed mechanically using the VHAD in accordance with 
the manufacturer's instructions as provided with the vehicle on which 
the headlamp is intended to be used.
    S14.2.5.5.3 Visually aimable lower beam headlamps-vertical aim.
    S14.2.5.5.3.1 A VOL cutoff headlamp must have the location of the 
cutoff maximum gradient, as determined by the method of this standard,

beam.
    S14.2.5.5.5.2 A headlamp whose upper beam is not combined with a 
lower beam must have its maximum beam intensity positioned on the H-H 
axis.
    S14.2.5.5.6 Visually aimable upper beam headlamps-horizontal aim.
    S14.2.5.5.6.1 A headlamp whose upper beam is combined with a lower 
beam must not have its horizontal aim

[[Page 68290]]

changed from that set for the lower beam.
    S14.2.5.5.6.2 A headlamp whose upper beam is not combined with a 
lower beam and has a fixed horizontal aim or has a horizontal VHAD must 
be mounted in its normal operating position on a goniometer such that 
the mounting fixture alignment axes are coincident with the goniometer 
axes and must be energized at 12.8 v  20 mv. There must be 
no adjustment, shimming, or modification of the horizontal axis of the 
headlamp or test fixture, unless the headlamp is equipped with a VHAD, 
in which case the VHAD must be adjusted to zero.
    S14.2.5.5.6.3 A headlamp whose upper beam is not combined with a 
lower beam and is not equipped with a horizontal VHAD, the horizontal 
aim must be adjusted so that the maximum beam intensity is positioned 
on the V-V axis.
    S14.2.5.5.7 Simultaneous aim Type F sealed beam headlamps and beam 
contributor integral beam headlamps.
    S14.2.5.5.7.1 A headlamp system permitted to use simultaneous aim 
of lower beams and upper beams must be aimed mechanically for lower 
beam photometry by centering the lower beam unit or the geometric 
center of all lower beam contributors on the photometer axis and 
aligning the aiming plane, aiming reference plane, or other appropriate 
vertical plane defined by the manufacturer perpendicular to the 
photometer axis.
    S14.2.5.5.7.2 The headlamp must be aimed for upper beam photometry 
by moving the assembly in a plane parallel to the established lower 
beam aiming plane until the upper beam unit or the geometric center of 
all upper beam contributors is centered in the photometric axis.
    S14.2.5.5.8 Motorcycle headlamp-upper beam headlamps designed to 
comply with Table XX. The upper beam of a multiple beam headlamp 
designed to comply with the requirements of Table XX must be aimed 
photoelectrically so that the center of the zone of highest intensity 
falls 0.4[deg] vertically below the lamp axis and is centered 
laterally. The center of the zone of highest intensity must be 
established by the intersection of a horizontal plane passing through 
the point of maximum intensity, and the vertical plane established by 
balancing the photometric values at 3[deg]L and 3[deg]R.
    S14.2.5.5.9 Motorcycle headlamp-lower beam headlamps designed to 
comply with Table XX. The beam from a single beam headlamp designed to 
comply with the requirements of Table XX must be aimed straight ahead 
with the top of the beam aimed vertically to obtain 2000 cd at H-V.
    S14.2.5.6 Positioner. The goniometer configuration, used to 
position the sample headlamp when making photometric measurements at 
specific angular test points, is horizontal rotation over elevation. 
The vertical axis of the goniometer must correspond to the design 
position vertical axis of the sample headlamp which is vertical and 
perpendicular to the longitudinal axis of the vehicle.
    S14.2.5.7 Photometer.
    S14.2.5.7.1 The photometer must be capable of measuring the 
luminous intensity of the sample headlamp throughout its illumination 
range.
    S14.2.5.7.2 Sensor.
    S14.2.5.7.2.1 The maximum effective area of the photometric sensor 
must fit within a circle whose diameter is equal to 0.009 times the 
actual test distance from the light source of the sample headlamp to 
the sensor.
    S14.2.5.7.2.2 The sensor effective area is defined as the actual 
area of intercepted light striking the detector surface of the 
photometer. Sensor systems incorporating lens(es) that change the 
diameter of the intercepted light beam before it reaches the actual 
detector surface, the maximum size requirements must apply to the total 
area of the light actually intercepted by the lens surface.
    S14.2.5.7.2.3 The sensor must be capable of intercepting all direct 
illumination from the largest illuminated dimension of the sample lamp 
at the test distance.
    S14.2.5.7.3 The color response of the photometer must be corrected 
to that of the 1931 International Commission on Illumination (C.I.E.) 
Standard Observer (2-degree) Photopic Response Curve, as shown in the 
C.I.E. 1931 Chromaticity Diagram (incorporated by reference, see 
571.108 S5.2 of this title).
    S14.2.5.8 Location of test points.
    S14.2.5.8.1 Test point positions are defined by the positioner. The 
following nomenclature applies:
    S14.2.5.8.1.1 The letters ``V'' and ``H'' designate the vertical 
and horizontal planes intersecting both the headlamp light source and 
the photometer axis. ``H-V'' designates the zero test point angle at 
the intersection of the H and V planes. This intersection is parallel 
to the longitudinal axis of the vehicle.
    S14.2.5.8.1.2 The letters ``U'', ``D'', ``L'', and ``R'', 
indicating up, down, left and right, respectively, designate the 
angular position from the H and V planes to the photometer as viewed 
from the headlamp.
    S14.2.5.8.1.3 Horizontal angles designated L and R are defined as 
the plan view angle between the vertical plane and the projection of 
the light ray from the headlamp onto the horizontal plane.
    S14.2.5.8.1.4 Vertical angles designated U and D are defined as the 
true angle between the horizontal plane and the light ray from the 
headlamp.
    S14.2.5.9 Beam contributor photometry measurements. In a 
headlighting system where there is more than one beam contributor 
providing a lower beam, and/or more than one beam contributor providing 
an upper beam, each beam contributor must be designed to meet only the 
applicable photometric performance requirements based upon the 
following mathematical expression: conforming test point value = 2(test 
point value)/total number of lower or upper beam contributors for the 
vehicle, as appropriate.
    S14.2.5.10 Moveable reflector aimed headlamp photometry 
measurements.
    S14.2.5.10.1 A headlamp aimed by moving the reflector relative to 
the lens and headlamp housing, or vice versa, must conform to the 
photometry requirements applicable to it with the lens at any position 
relative to the reflector.
    S14.2.5.10.2 These positions include not less than the full range 
of vertical pitch of the vehicle on which the headlamp is installed and 
not less than  2.5[deg] from the nominal horizontal aim 
position for the vehicle on which the headlamp is installed unless the 
headlamp is visually/optically aimed with a fixed horizontal aim.
    S14.3 Motorcycle headlamp out of focus test procedure and 
performance requirements.
    S14.3.1 Procedure. The sample device must be tested for photometry 
using bulbs having each of four out-of-focus filament positions. Where 
conventional bulbs with two pin bayonet bases are used, tests must be 
made with the light source 0.060 in above, below, ahead, and behind the 
designated position. If prefocused bulbs are used, the limiting 
positions at which tests are made must be 0.020 in above, below, ahead, 
and behind the designated position. The sample device may be re-aimed 
for each of the out-of-focus positions of the light source.
    S14.3.2 Performance requirements. The minimum photometric values 
for the out-of-design position must be 80% of the in-design position.
    S14.4 General test procedures and performance requirements.
    S14.4.1 Color test. The requirement applies to the overall 
effective color of light emitted by the device and not to

[[Page 68291]]

the color of the light from a small area of the lens. It does not apply 
to any pilot, indicator, or tell-tale lights. The color of the sample 
device must comply when tested by either the Visual Method or the 
Tristimulus Method.
    S14.4.1.1 Samples. A test sample for a reflex reflector may be 
either the reflex reflector or a disc of the same material, technique 
of fabrication, and dye formulation as the reflex reflector. If a disc 
is used, the thickness must be twice the thickness of the reflector as 
measured from the face of the lens to the apexes of the reflecting 
elements.
    S14.4.1.2 General procedure.
    S14.4.1.2.1 The device must be operated at design voltage.
    S14.4.1.2.2 Components (bulbs, caps, lenses, and the like) must be 
tested in a fixture or manner simulating the intended application.
    S14.4.1.2.3 The lamp shall be allowed to reach operating 
temperature before measurements are made.
    S14.4.1.2.4 The entire light emitting surface of the sample must be 
visible from any point on the entrance window of the test instrument.
    S14.4.1.2.5 The distance between the test instrument and the sample 
must be large enough so that further increases in distance will not 
affect the results.
    S14.4.1.3 Visual method.
    S14.4.1.3.1 Visual method procedure. The color of light from the 
sample device must be compared visually with the color of the light 
from a standard. The standard may consist of a filter or limit glass. 
In the case of white, CIE Source A is used only as a color reference. 
The chromaticity coordinates of the color standards must be as close as 
possible to the limits listed. The color of the standard filters is 
determined spectro-photometrically.
    S14.4.1.3.2 Visual method performance requirements. The color must 
comply with the applicable requirement.
    S14.4.1.3.2.1 Red. Red is not acceptable if it is less saturated 
(paler), yellower, or bluer than the limit standards.
    S14.4.1.3.2.2 Yellow (Amber). Yellow is not acceptable if it is 
less saturated (paler), greener, or redder than the limit standards.
    S14.4.1.3.2.3 White. White is not acceptable if its color differs 
materially from that of CIE Source A.
    S14.4.1.4 Tristimulus method.
    S14.4.1.4.1 Tristimulus method procedure.
    S14.4.1.4.1.1 The color of light from the H-V point of a sample 
device must be measured by photoelectric receivers with spectral 
responses that approximate CIE standard spectral tristimulus valves.
    S14.4.1.4.1.2 A sphere may be used to integrate light from a 
colored source provided that the color shift that results from the 
spectral selectivity of the sphere paint be corrected by the use of a 
filter, correction factor, or an appropriate calibration.
    S14.4.1.4.1.3 Where the sample device does not have uniform 
spectral characteristics in all useful directions, color measurements 
must be made at as many directions of view as are required to evaluate 
the color for those directions that apply to the end use of the device.
    S14.4.1.4.2 Tristimulus method performance requirements. The color 
must comply with the applicable requirement.
    S14.4.1.4.2.1 Red. The color of light emitted must fall within the 
following boundaries:

y = 0.33 (yellow boundary)
y = 0.98 - x (purple boundary)

    S14.4.1.4.2.2 Yellow (Amber). The color of light emitted must fall 
within the following boundaries:

y = 0.39 (red boundary)
y = 0.79 - 0.67x (white boundary)

y = 0.44 (green boundary)
x = 0.50 (yellow boundary)
y = 0.15 + 0.64x (green boundary)
y = 0.38 (red boundary)
y = 0.05 + 0.75x (purple boundary)

    S14.4.2 Plastic optical materials tests. Accelerated weathering 
procedures are not permitted.
    S14.4.2.1 Samples.
    S14.4.2.1.1 Samples of materials shall be injection molded into 
polished metal molds to produce test specimens with two flat and 
parallel faces. Alternative techniques may be used to produce 
equivalent specimens.
    S14.4.2.1.2 Test specimens shape may vary, but each exposed surface 
must contain a minimum uninterrupted area of 32 sq cm.
    S14.4.2.1.3 Samples must be furnished in thicknesses of 1.6 < plus-
minus> 0.25 mm, 2.3  0.25 mm, 3.2  0.25 mm, and 
6.4  0.25 mm.
    S14.4.2.1.4 All samples must conform to the applicable color test 
requirement of this standard prior to testing.
    S14.4.2.1.5 A control sample, kept properly protected from 
influences which may change its appearance and properties of each 
thickness, must be retained.
    S14.4.2.2 Outdoor exposure test.
    S14.4.2.2.1 Outdoor exposure tests of 3 years in duration must be 
made on samples of all materials, including coated and uncoated 
versions, used for optical parts of devices covered by this standard. 
Tests are to be conducted in Florida and Arizona.
    S14.4.2.2.2 Concentrations of polymer components and additives used 
in plastic materials may be changed without outdoor exposure testing 
provided the changes are within the limits of composition represented 
by higher and lower concentrations of these polymer components and 
additives previously tested to this section and found to meet its 
requirements.
    S14.4.2.2.3 Procedure.
    S14.4.2.2.3.1 One sample of each thickness of each material must be 
mounted at each exposure site so that at least a minimum uninterrupted 
area of 32 sq cm of the exposed upper surface of the sample is at an 
angle of 45[deg] to the horizontal facing south. The sample must be 
mounted in the open no closer than 30 cm (11.8 in) to its background.
    S14.4.2.2.3.2 During the exposure time the samples must be cleaned 
once every three months by washing with mild soap or detergent and 
water, and then rinsing with distilled water. Rubbing must be avoided.
    S14.4.2.2.4 Performance requirements. Plastic lenses, other than 
those incorporating reflex reflectors, used for inner lenses or those 
covered by another material and not exposed directly to sunlight must 
meet the optical material test requirements when covered by the outer 
lens or other material.
    S14.4.2.2.4.1 After completion of the outdoor exposure test the 
haze and loss of surface luster as measured by ASTM 1003-92, Haze and 
Luminous Transmittance of Transparent Plastic, (incorporated by 
reference, see 571.108 S5.2 of this title) must not be greater than:
    (a) 30% for materials used for outer lenses, other than those 
incorporating reflex reflectors;
    (b) 7% for materials used for reflex reflectors and lenses used in 
front of reflex reflectors.
    S14.4.2.2.4.2 After completion of the outdoor exposure test 
materials used for headlamp lenses must show no deterioration.
    S14.4.2.2.4.3 After completion of the outdoor exposure test all 
materials, when compared with the unexposed control samples, must not 
show physical changes affecting performance such as color bleeding, 
delamination, crazing, or cracking. Additionally materials used for 
reflex reflectors and lenses used in front of reflex reflectors

[[Page 68292]]

must not show surface deterioration or dimensional changes.
    S14.4.2.2.4.4 After completion of the outdoor exposure test all 
materials, when compared with the unexposed control samples, must not 
have their luminous transmittance changed by more than 25% when tested 
in accordance with ASTM E 308-66 (1973), Spectrophotmetry and 
Description of Color in CIE 1931 System (incorporated by reference, see 
571.108 S5.2 of this title) using CIE Illuminant A (2856K).
    S14.4.2.2.4.5 After completion of the outdoor exposure test all 
materials must conform to the color test of this standard in the range 
of thickness stated by the material manufacturer.
    S14.4.2.3 Heat test.
    S14.4.2.3.1 Procedure. Two samples of each thickness of each 
material must be supported at the bottom, with at least 51 mm of the 
sample above the support, in the vertical position in such a manner 
that, on each side, the minimum uninterrupted area of exposed surface 
is not less than 3225 sq mm. The samples are placed in a circulating 
air oven at 79  3 [deg]C for two hours.
    S14.4.2.3.2 Performance requirements. After completion of the heat 
exposure and cooling to room ambient temperature, a test specimen must 
show no change in shape and general appearance discernable to the naked 
eye when compared with an unexposed specimen and continue to conform to 
the applicable color test requirement of this standard.
    S14.5 Signal lamp and reflective device physical test procedures 
and performance requirements.
    S14.5.1 Vibration test.
    S14.5.1.1 Procedure. The sample device, as mounted on the support 
supplied, must be bolted to the anvil end of the table of the vibration 
test machine of Figure 21 and vibrated approximately 750 cpm through a 
distance of \1/8\ in. The table must be spring mounted at one end and 
fitted with steel calks on the underside of the other end. The calks 
are to make contact with the steel anvil once during each cycle at the 
completion of the fall. The rack must be operated under a spring 
tension of 60 to 70 lb. The test must be continued for 1 hour.
    S14.5.1.2 Performance requirements. After completion of the 
vibration test a device showing evidence of material physical weakness, 
lens or reflector rotation, displacement or rupture of parts except 
bulb failures, must be considered to have failed, providing that the 
rotation of lens or reflector must not be considered as a failure when 
tests show compliance with specifications despite such rotation.
    S14.5.2 Moisture test.
    S14.5.2.1 Procedure. The sample device must be mounted in its 
normal operating position with all drain holes open and subjected to a 
precipitation of 0.1 in of water per minute, delivered at an angle of 
45[deg] from a nozzle with a solid cone spray. During the test the 
device must revolve about its vertical axis at a rate of 4 rpm for a 
period of 12 hours followed by a one hour drain period where the device 
does not rotate and the spray stops. After completion of the moisture 
test the device must be examined for moisture accumulation.
    S14.5.2.2 Performance requirements. Accumulation of moisture in 
excess of 2 cc or any visible moisture in a sealed reflex unit must 
constitute a failure.
    S14.5.3 Dust test.
    S14.5.3.1 Samples. A sealed unit is not required to meet the 
requirements of this test.
    S14.5.3.2 Procedure. The sample device with any drain hole closed 
must be mounted in its normal operating position, at least 6 in from 
the wall in a cubical box with inside measurements of 3 ft on each side 
containing 10 lb of fine powered cement in accordance with ASTM C 150-
56, Standard Specification for Portland Cement (incorporated by 
reference, see 571.108 S5.2 of this title). At intervals of 15 minutes 
during a test period of 5 hours, the dust must be agitated by 
compressed air or fan blower by projecting blasts of air for a 2 second 
period in a downward direction into the dust in such a way that the 
dust is completely and uniformly diffused throughout the entire cube 
and allowed to settle. After the completion of the dust test the 
exterior surface of the device must be cleaned.
    S14.5.3.3 Performance requirements. If after a photometry test the 
maximum photometric intensity of the device is not more than 10% less 
than the maximum photometric intensity of the same device after being 
cleaned both inside and outside, the device is considered to have met 
the requirements of the dust test.
    S14.5.4 Corrosion test.
    S14.5.4.1 Procedure. The sample device must be subjected to a salt 
spray (fog) test in accordance with the latest version of ASTM B117-73, 
Method of Salt Spray (Fog) Testing (incorporated by reference, see 
571.108 S5.2 of this title), for a period of 50 hours, consisting of 
two periods of 24 hour exposure followed by a 1 hr drying time.
    S14.5.4.2 Performance requirements. After the completion of the 
corrosion test there must be no evidence of excessive corrosion which 
would affect the proper function of the device.
    S14.6 Headlamp physical test procedures and performance 
requirements.
    S14.6.1 Abrasion test.
    S14.6.1.1 Procedure.

0000 steel wool not less than 2.5  .1 cm wide, rubber 
cemented to a rigid base shaped to the same vertical contour of the 
lens, is used for each test. The abrading pad support is equal in size 
to the pad and the center of the support surface is within  
2 mm of parallel to the lens surface. The ``grain'' of the pad is 
oriented perpendicular to the direction of motion. The density of the 
pad is such that when the pad is resting unweighted on the lens, the 
base of the pad is no closer than 3.2 mm to the lens at its closest 
point.
    S14.6.1.1.2 Abrading pad alignment. A sample headlamp is mounted in 
the abrasion test fixture of Figure 5 with the lens facing upward. When 
mounted on its support and resting on the lens of the test headlamp, 
the abrading pad is then weighted such that a pad pressure of 14 < plus-
minus> 1 KPa. exists at the center and perpendicular to the face of the 
lens.
    S14.6.1.1.3 Abrasion test procedure. The pad is cycled back and 
forth (1 cycle) for 11 cycles at 4  0.8 in (10  
2 cm) per second over at least 80% of the lens surface, including all 
the area between the upper and lower aiming pads, but not including 
lens trim rings and edges. A pivot must be used if it is required to 
follow the contour of the lens.
    S14.6.1.2 Performance requirements. After completion of the 
abrasion test the sample headlamp must meet the requirements of the 
applicable photometry tests of Table XIX and Table XVIII. A \1/4\[deg] 
reaim is permitted in any direction at any test point.

    S14.6.2.1.2 Fluid application. The entire exterior lens surface of 
the sample headlamp mounted in the headlamp test fixture and top 
surface of the lens-reflector joint is wiped once to the left and once 
to the right with a 6 inch square soft cotton cloth (with pressure 
equally applied) which has been saturated once in a container with 2 
ounces of five different test fluids listed above. The lamp is wiped 
within 5 seconds after removal of the cloth from the test fluid. A new 
lamp sample may be used with each fluid.
    S14.6.2.1.3 Test duration. After the headlamp sample has been wiped 
with the test fluid, it must be stored in its designed operating 
attitude for 48 hours at a temperature of 23[deg]C  4[deg]C 
and a relative humidity of 30%  10%. At the end of the 48-
hour period, the headlamp is wiped clean with a soft dry cotton cloth 
and visually inspected.
    S14.6.2.2 Performance requirements. After completion of the 
chemical resistance test, the sample headlamp must have no surface 
deterioration, coating delamination, fractures, deterioration of 
bonding or sealing materials, color bleeding, or color pickup visible

4\[deg] reaim is permitted in any direction at any test point.
    S14.6.3 Corrosion test.
    S14.6.3.1 Procedure. A sample headlamp, mounted on a headlamp test 
fixture in designed operating position and including all accessory 
equipment necessary to operate in its normal manner, is subjected to a 
salt spray (fog) test in accordance with ASTM B117-73, Method of Salt 
Spray (Fog) Testing (incorporated by reference, see 571.108 S5.2 of 
this title), for 50 total hours, consisting of two periods of 24 hours 
exposure followed by a 1 hour drying period. If a portion of the device 
is completely protected in service, that portion is covered to prevent 
salt fog entry during exposure. After removal from the salt spray and 
the final 1 hour drying period the sample headlamp is examined for 
corrosion that affect any other applicable tests contained in S14.6. If 
such corrosion is found, the affected test(s) must be performed on the 
corrosion sample and the results recorded.
    S14.6.3.2 Performance requirements. After completion of the 
corrosion test, the sample headlamp must not have any observed 
corrosion which would result in the failure of any other applicable 
tests contained in S14.6 and no corrosion of the headlamp mounting and 
aiming mechanism that would result in the failure of the aiming 
adjustment tests, inward force test, or torque deflection test of 
S14.6.
    S14.6.4 Corrosion-connector test.
    S14.6.4.1 Procedure.
    S14.6.4.1.1 A headlamp connector test must be performed on each 
filament circuit of the sample headlamp prior to the test in 
S14.6.4.1.2 according to Figure 4 and S14.6.15. The power source is set 
to provide 12.8 volts and the resistance must be set to produce 10 
amperes.
    S14.6.4.1.2 The headlamp, with connector attached to the terminals, 
unfixtured and in its designed operating attitude with all drain holes, 
breathing devices or other designed openings in their normal operating 
positions, is subjected to a salt spray (fog) test in accordance with 
ASTM B117-73, Method of Salt Spray (Fog) Testing (incorporated by 
reference, see 571.108 S5.2 of this title), for 240 hours, consisting 
of ten successive 24-hour periods.
    S14.6.4.1.3 During each period, the headlamp is mounted in the 
middle of the chamber and exposed for 23 hours to the salt spray. The 
spray is not activated during the 24th hour. The bulb is removed from 
the headlamp and from the test chamber during the one hour of salt 
spray deactivation and reinserted for the start of the next test 
period, at the end of the first and last three 23-hour periods of salt 
spray exposure, and at the end of any two of the fourth through seventh 
23-hour periods of salt-spray exposure.
    S14.6.4.1.4 The test chamber is closed at all times except for a 
maximum of 2 minutes which is allowed for removal or replacement of a 
bulb during each period.
    S14.6.4.1.5 After the ten periods, the lens-reflector unit without 
the bulb must be immersed in deionized water for 5 minutes, then 
secured and allowed to dry by natural convection only.
    S14.6.4.1.6 Using the voltage, resistance and pre-test set up of 
S14.6.4.1.1 the current in each filament circuit must be measured after 
the test conducted in S14.6.4.1.2.
    S14.6.4.2 Performance requirements.
    S14.6.4.2.1 After the completion of the corrosion-connector test, 
the sample headlamp must show no evidence of external or internal 
corrosion or rust visible without magnification.
    S14.6.4.2.2 Loss of adhesion of any applied coating must not occur 
more than 3.2 mm from any sharp edge on the inside or out.
    S14.6.4.2.3 Corrosion may occur on terminals only if the test 
current produced during the test of S14.6.4.1.6 is not less than 9.7 
amperes.
    S14.6.5 Dust test.
    S14.6.5.1 Procedure.
    S14.6.5.1.1 A sample headlamp, mounted on a headlamp test fixture, 
with all drain holes, breathing devices or other designed openings in 
their normal operating positions, is positioned within a cubical box, 
with inside measurements of 900 mm on each side or larger if required 
for adequate wall clearance (i.e., a distance of at least 150 mm 
between the headlamp and any wall of the box).
    S14.6.5.1.2 The box contains 4.5 kg of fine powdered cement which 
conforms to the ASTM C150-77, Standard Specification for Portland 
Cement (incorporated by reference, see 571.108 S5.2 of this title). 
Every 15 minutes, the cement is agitated by compressed air or fan 
blower(s) by projecting blasts of air for a two-second period in a 
downward direction so that the cement is diffused as uniformly as 
possible throughout the entire box.
    S14.6.5.1.3 This test is continued for five hours after which the 
exterior surfaces of the headlamp are wiped clean.
    S14.6.5.2 Performance requirements. After completion of the dust 
test, the sample headlamp must meet the requirements of the applicable 
photometry tests of Table XIX and Table XVIII. A \1/4\[deg] reaim is 
permitted in any direction at any test point.
    S14.6.6 Temperature cycle test and internal heat test.
    S14.6.6.1 Samples. A sample headlamp with one or more replaceable 
light sources is tested according to the procedures of this section for 
a temperature cycle test and an internal heat test. The same sample 
headlamp is used in the temperature cycle test and then in the internal 
heat test.
    S14.6.6.2 General procedure.

[[Page 68294]]

    S14.6.6.2.1 Tests are made with all filaments lighted at design 
voltage that are intended to be used simultaneously in the headlamp and 
which in combination draw the highest total wattage. These include but 
are not limited to filaments used for turn signal lamps, fog lamps, 
parking lamps, and headlamp lower beams lighted with upper beams when 
the wiring harness is so connected on the vehicle.
    S14.6.6.2.2 If a turn signal is included in the headlamp assembly, 
it is operated at 90 flashes a minute with a 75%  2% 
current ``on time.''
    S14.6.6.2.3 If the lamp produces both the upper and lower beam, it 
is tested in both the upper beam mode and the lower beam mode under the 
conditions above described, except for a headlamp with a single type 
HB1 or type HB2 light source.
    S14.6.6.3 Temperature cycle test.
    S14.6.6.3.1 Procedure.
    S14.6.6.3.1.1 A sample headlamp, mounted on a headlamp test 
fixture, is subjected to 10 complete consecutive cycles having the 
thermal cycle profile shown in Figure 6.
    S14.6.6.3.1.2 During the hot cycle, the lamp, is energized 
commencing at point ``A'' of Figure 6 and de-energized at point ``B.''
    S14.6.6.3.1.3 Separate or single test chambers may be used to 
generate the environment of Figure 6.
    S14.6.6.3.1.4 All drain holes, breathing devices or other openings 
or vents of the headlamps are set in their normal operating positions.
    S14.6.6.3.2 Performance requirements. After completion of the 
temperature cycle test, the sample headlamp must:
    (a) show no evidence of delamination, fractures, entry of moisture, 
or deterioration of bonding material, color bleeding, warp or 
deformation visible without magnification;
    (b) show no lens warpage greater than 3 mm when measured parallel 
to the optical axis at the point of intersection of the axis of each 
light source with the exterior surface of the lens; and
    (c) meet the requirements of the applicable photometry tests of 
Table XIX and Table XVIII. A \1/4\[deg] reaim is permitted in any 
direction at any test point.
    S14.6.6.4 Internal heat test.
    S14.6.6.4.1 Procedure.
    S14.6.6.4.1.1 A sample headlamp lens surface that would normally be 
exposed to road dirt is uniformly sprayed with any appropriate mixture 
of dust and water or other materials to reduce the photometric output 
at the H-V test point of the upper beam (or the \1/2\[deg]D-1\1/
2\[deg]R test point of the lower beam as applicable) to 25% < plus-
minus> 2% of the output originally measured in the applicable 
photometric compliance test.
    S14.6.6.4.1.2 A headlamp with a single type HB1 or type HB2 light 
source is tested on the upper beam only.
    S14.6.6.4.1.3 Such reduction is determined under the same 
conditions as that of the original photometric measurement.
    S14.6.6.4.1.4 After the photometric output of the lamp has been 
reduced as specified above, the sample lamp and its mounting hardware 
must be mounted in an environmental chamber in a manner similar to that 
indicated in Figure 7 ``Dirt/Ambient Test Setup.''
    S14.6.6.4.1.5 The headlamp is soaked for one hour at a temperature 
of 35[deg] + 4[deg] - 0 [deg]C) and then the lamp is energized 
according to the procedure of this section for one hour in a still air 
condition, allowing the temperature to rise from the soak temperature.
    S14.6.6.4.1.6 At the end of one hour the sample lamp is returned to 
a room ambient temperature of 23[deg] + 4[deg] - 0 [deg]C and a 
relative humidity of 30%  10% and allowed to stabilize to 
the room ambient temperature. The lens is then cleaned.
    S14.6.6.4.2 Performance requirements. After completion of the 
temperature cycle test and meeting its requirements, and completion of 
the internal heat test, the sample headlamp must:
    (a) have no lens warpage greater than 3 mm when measured parallel 
to the optical axis at the point of intersection of the axis of each 
light source with the exterior surface of the lens, and
    (b) meet the requirements of the applicable photometry tests of 
Table XIX and Table XVIII. A \1/4\[deg] reaim is permitted in any 
direction at any test point.
    S14.6.7 Humidity test.
    S14.6.7.1 Procedure.
    S14.6.7.1.1 The test fixture consists of a horizontal steel plate 
to which three threaded steel or aluminum rods of \1/2\ inch diameter 
are screwed vertically behind the headlamp.
    S14.6.7.1.2 The sample headlamp assembly is clamped to the vertical 
rods, which are behind the headlamp. All attachments to the headlamp 
assembly are made behind the lens and vents or openings, and are not 
within 2 inches laterally of a vent inlet or outlet.
    S14.6.7.1.3 The mounted headlamp assembly is oriented in its design 
operating position, and is placed in a controlled environment at a 
temperature of 100[deg] + 7[deg]-0[deg] F (38[deg] + 4[deg]-0[deg] C) 
with a relative humidity of not less than 90%. All drain holes, 
breathing devices, and other openings are set in their normal operation 
positions for all phases of the humidity test.
    S14.6.7.1.4 The headlamp is subjected to 24 consecutive 3-hour test 
cycles. In each cycle, the headlamp is energized for 1 hour at design 
voltage with the highest combination of filament wattages that are 
intended to be used, and then de-energized for 2 hours. If the headlamp 
incorporates a turn signal then the turn signal flashes at 90 flashes 
per minute with a 75%  2% current ``on-time.''
    S14.6.7.1.5 Within 3 minutes after the completion of the 24th 
cycle, the air flow test will begin. The following procedure shall 
occur: the mounted assembly is removed, placed in an insulating box and 
covered with foam material so that there is no visible air space around 
the assembly; the box is closed, taken to the air flow test chamber, 
and placed within it. Inside the chamber, the assembly with respect to 
the air flow, is oriented in its design operating position. The 
assembly is positioned in the chamber so that the center of the lens is 
in the center of the opening of the air flow entry duct during the 
test. The headlamp has at least 3 inches clearance on all sides, and at 
least 4 inches to the entry and exit ducts at the closest points. If 
vent tubes are used which extend below the lamp body, the 3 inches are 
measured from the bottom of the vent tube or its protection. The 
temperature of the chamber is 73[deg] + 7[deg] - 0 [deg]F (23[deg] + 
4[deg] - 0 [deg]C) with a relative humidity of 30% + 10% - 0%. The 
headlamp is not energized.
    S14.6.7.1.6 Before the test specified in paragraph S14.6.7.1.7 of 
this section, the uniformity of the air flow in the empty test chamber 
at a plane 4 inches downstream of the air entry duct is measured over a 
4 inch square grid. The uniformity of air flow at each grid point is 
 10% of the average air flow specified in paragraph 
S14.6.7.1.7 of this section.
    S14.6.7.1.7 The mounted assembly in the chamber is exposed, for one 
hour, to an average air flow of 330 +0 -30 ft/min as measured with an 
air velocity measuring probe having an accuracy of  3% in 
the 330 ft/min range. The average air flow is the average of the 
velocity recorded at six points around the perimeter of the lens. The 
six points are determined as follows: At the center of the lens, 
construct a horizontal plane. The first two points are located in the 
plane, 1 inch outward from the intersection of the plane and each edge 
of the lens. Then, trisect the distance between these two points and 
construct longitudinal vertical planes at the two intermediate 
locations formed by the

[[Page 68295]]

trisection. The four remaining points are located in the vertical 
planes, one inch above the top edge of the lens, and one inch below the 
bottom edge of the lens.
    S14.6.7.1.8 After one hour, the headlamp is removed and inspected 
for moisture.
    S14.6.7.2 Performance requirements. After completion of the 
humidity test, the sample headlamp must show no evidence of interior 
delamination or moisture, fogging or condensation visible without 
magnification.
    S14.6.8 Vibration test.
    S14.6.8.1 Samples. The mounting bracket with a sample headlamp 
installed must not have a resonant frequency in the 10-55 Hz. range.
    S14.6.8.2 Procedure. The mounted sample headlamp is bolted to the 
anvil end of the table of the vibration test machine of Figure 21 and 
vibrated 750 cpm through a distance of 1/8 in. The table is spring 
mounted at one end and fitted with steel calks on the underside of the 
other end. The table is of sufficient size to completely contain the 
test fixture base with no overhang. The calks are to make contact with 
the steel anvil once during each cycle at the completion of the fall. 
The rack is operated under a spring tension of 60 to 70 lb. The 
vibration is applied in the vertical axis of the headlamp as mounted on 
the vehicle. Bulb filaments are not energized during the test. The test 
is continued for 1 hour.
    S14.6.8.3 Performance requirements. After completion of the 
vibration test, there must be no evidence of loose or broken parts, 
other than filaments, visible without magnification.
    S14.6.9 Sealing test.
    S14.6.9.1 Procedure.
    S14.6.9.1.1 An unfixtured sample headlamp in its design mounting 
position is placed in water at a temperature of 176[deg]  
5[deg] F (60[deg]  3[deg] C) for one hour. The headlamp is 
energized in its highest wattage mode, with the test voltage at 12.8 
 0.1V during immersion.
    S14.6.9.1.2 The lamp is then de-energized and immediately submerged 
in its design mounting position into water at 32[deg] +5[deg] -0[deg] F 
(0[deg] +3[deg] -0[deg] C). The water is in a pressurized vessel, and 
the pressure is increased to 10 psi (70 kPa), upon placing the lamp in 
the water. The lamp must remain in the pressurized vessel for a period 
of thirty minutes.
    S14.6.9.1.3 This entire procedure is repeated for four cycles.
    S14.6.9.1.4 Then the lamp is inspected for any signs of water on 
its interior. During the high temperature portion of the cycles, the 
lamp is observed for signs of air escaping from its interior.
    S14.6.9.2 Performance requirements. After completion of the sealing 
test, a sample headlamp confirmed to be sealed need not meet the 
corrosion test, dust test, or humidity test of this Section. If any 
water is on the interior or air escapes, the lamp is not a sealed lamp.
    S14.6.10 Chemical resistance test of reflectors of replaceable lens 
headlamps test.
    S14.6.10.1 Procedure.
    S14.6.10.1.1 Test fluids. The three test fluids used in the 
chemical resistance test include;
    (a) Tar remover (consisting by volume of 45% xylene and 55% 
petroleum base mineral spirits);
    (b) Mineral spirits; and
    (c) Fluids other than water contained in the manufacturer's 
instructions for cleaning the reflector.
    S14.6.10.1.2 Fluid application. With a sample headlamp in the 
headlamp test fixture and the lens removed, the entire surface of the 
reflector that receives light from a headlamp light source is wiped 
once to the left and once to the right with a 6-inch square soft cotton 
cloth (with pressure equally applied) which has been saturated once in 
a container with 2 ounces of one of the test fluids listed in 
S14.6.10.1.1. The lamp is wiped within 5 seconds after removal of the 
cloth from the test fluid.
    S14.6.10.1.3 Test duration. After the headlamp has been wiped with 
the test fluid, it is stored in its designed operating attitude for 48 
hours at a temperature of 73[deg]  7[deg] F (23[deg]  4[deg] C) and a relative humidity of 30%  10%. At 
the end of the 48-hour period, the headlamp is wiped clean with a soft 
dry cotton cloth and visually inspected.
    S14.6.10.2 Performance requirements. After completion of the 
chemical resistance test, the sample headlamp must have no surface 
deterioration, coating delamination, fractures, deterioration of 
bonding or sealing materials, color bleeding or color pickup visible 
without magnification and the headlamp must meet the requirements of 
the applicable photometry tests of Table XIX and Table XVIII. A \1/
4\[deg] re-aim is permitted in any direction at any test point.
    S14.6.11  Corrosion resistance test of reflectors of replaceable 
lens headlamps test.
    S14.6.11.1 Procedure.
    S14.6.11.1.1 A sample headlamp with the lens removed, unfixtured 
and in its designed operating attitude with all drain holes, breathing 
devices or other designed openings in their normal operating positions, 
must be subjected to a salt spray (fog) test in accordance with ASTM 
B117-73, Method of Salt Spray (Fog) Testing (incorporated by reference, 
see 571.108 S5.2 of this title), for 24 hours, while mounted in the 
middle of the chamber.
    S14.6.11.1.2 Afterwards, the headlamp must be stored in its 
designed operating attitude for 48 hours at a temperature of 73[deg] 
 7[deg] F (23[deg]  4[deg] C) and a relative 
humidity of 30%  10% and allowed to dry by natural 
convection only. At the end of the 48-hour period, the reflector must 
be cleaned according to the instructions supplied with the headlamp 
manufacturer's replacement lens, and inspected. The lens and seal must 
then be attached according to these instructions and the headlamp 
tested for photometric performance.
    S14.6.11.2 Performance requirements. After the completion of the 
corrosion test, the sample headlamp must show no evidence of corrosion 
or rust visible without magnification on any part of the headlamp 
reflector that receives light from a headlamp light source, on any 
metal light or heat shield assembly, or on a metal reflector of any 
other lamp. The sample headlamp with the replacement lens installed 
must meet the requirements of the applicable photometry tests of Table 
XIX and Table XVIII. A \1/4\[deg] re-aim is permitted in any direction 
at any test point.
    S14.6.12 Inward force test.
    S14.6.12.1 Procedure. A sample headlamp mechanism, including the 
aiming adjusters, must be subjected to an inward force of 222 N 
directed normal to the headlamp aiming plane and symmetrically about 
the center of the headlamp lens face.
    S14.6.12.2 Performance requirements. After the completion of the 
inward force test, a sample headlamp must not permanently recede by 
more than 2.5 mm. The aim of the headlamp must not permanently deviate 
by more than 3.2 mm at a distance of 7.6 m. The aim of any headlamp 
that is capable of being mechanically aimed by externally applied 
aiming devices must not change by more than 0.30[deg].
    S14.6.13 Torque deflection test.
    S14.6.13.1 Procedure.
    S14.6.13.1.1 The sample headlamp assembly is mounted in designed 
vehicle position and set at nominal aim (H=0, V=0).
    S14.6.13.1.2 A sealed beam headlamp, except Type G and Type H, is 
removed from its mounting and replaced by the applicable deflectometer. 
(Type C and Type D-Figure 18, Type A and Type E-Figure 16, Type B-
Figure 17, and Type F-Figure 14).

[[Page 68296]]

    S14.6.13.1.3 Sealed beam headlamps Type G and Type H have the 
adapter of Figure 15 and the deflectometer of Figure 14 attached to the 
headlamp.
    S14.6.13.1.4 A torque of 2.25 Nm must be applied to the headlamp 
assembly through the deflectometer and a reading on the thumbwheel is 
taken. The torque must be removed and a second reading on the 
thumbwheel is taken.
    S14.6.13.1.5 Headlamps other than sealed beam headlamps must have 
the downward force used to create the torque applied parallel to the 
aiming reference plane, through the aiming pads, and displaced forward 
using a lever arm such that the force is applied on an axis that is 
perpendicular to the aiming reference plane and originates at the 
center of the aiming pad pattern (see Figure 3).
    S14.6.13.1.6 For headlamps using the aiming pad locations of Group 
I, the distance between the point of application of force and the 
aiming reference plane is not less than 168.3 mm plus the distance from 
the aiming reference plane to the secondary plane, if used.
    S14.6.13.1.7 For headlamps using the aiming pad locations of Group 
II, the distance between the point of application of force and the 
aiming reference plane is not less than 167.9 mm plus the distance to 
the secondary plane, if used.
    S14.6.13.1.8 For headlamps using the nonadjustable Headlamp Aiming 
Device Locating Plates for the 146 mm diameter, the 176 mm diameter, 
and the 92x150 mm sealed beam, the distance between the point of

fixture in a manner indicated in Figure 8, a force 4.0  0.1 
pounds (17.8  0.4N) is applied at a distance ``A'' from the 
reference plane perpendicular to the longitudinal axis of the glass 
capsule and parallel to the smallest dimension of the pressed glass 
capsule seal.

[[Page 68297]]

    S14.7.1.1.2 The force is applied (using a rod with a hard rubber 
tip with a minimum spherical radius of .039 in [1 mm]) radially to the 
surface of the glass capsule in four locations in a plane parallel to 
the reference plane and spaced at a distance ``A'' from that plane. 
These force applications are spaced 90[deg] apart starting at the point 
perpendicular to the smallest dimension of the pressed seal of the 
glass capsule.
    S14.7.1.1.3. The bulb deflection is measured at the glass capsule 
surface at 180[deg] opposite to the force application. Distance ``A'' 
for a replaceable light source other than an HB Type is the dimension 
provided in accordance with Appendix A of part 564 of this chapter, 
section I.A.1 if the light source has a lower beam filament, or as 
specified in section I.B.1 if the light source has only an upper beam 
filament.

each sample Type HB1, Type HB3, Type HB4, and Type HB5 light source, 
and on any other replaceable light source which uses a seal, is 
installed in a pressure chamber as shown in Figure 10 so as to provide 
an airtight seal. The diameter of the aperture in Figure 10 on a 
replaceable light source (other than an HB Type) must be that dimension 
furnished for such light source in compliance with Appendix A or 
Appendix B of part 564 of this chapter.
    S14.7.2.1.2 The light source is immersed in water for one minute 
while inserted in a cylindrical aperture specified for the light 
source, and subjected to an air pressure of 70 KPa (10 psig) on the 
glass capsule side.
    S14.7.2.2 Performance requirements. After completion of the 
pressure test, the sample light source with an airtight seal on the low 
pressure (connector side) must show no evidence of air bubbles on that 
side.

this chapter, or section IV of Appendix B of part 564 of this chapter, 
is made in accordance with this paragraph.
    S14.7.3.1 Seasoning. The filament or discharge arc is seasoned 
before measurement of either maximum power and luminous flux.
    S14.7.3.1.1 Resistive filament source. Seasoning of a light source 
with a resistive element type filament is made in accordance with this 
S14.2.5.4 of this standard.

flux is made in accordance with the Illuminating Engineering Society of 
North America, LM 45; IES Approved Method for Electrical and 
Photometric Measurements of General Service Incandescent Filament Lamps 
(April 1980) (incorporated by reference, see 571.108 S5.2 of this 
title).
    S14.7.3.3.1 Resistive filament light source setup. Luminous flux 
measurements are made with the black cap installed on Type HB1, Type 
HB2, Type HB4, and Type HB5, and on any other replaceable light source 
so designed; and is with the electrical conductor and light source base 
shrouded with an opaque white cover, except for the portion normally 
located within the interior of the lamp housing. The measurement of 
luminous flux for the Types HB3 and HB4 is made with the base covered 
with a white cover as shown in the drawings for Types HB3 and HB4 filed 
in Docket No. NHTSA 98-3397. The white covers are used to eliminate the 
likelihood of incorrect lumen measurement that will occur should the 
reflectance of the light source base and electrical connector be low.
    S14.7.3.3.2 Discharge light source setup. With the test voltage 
applied to the ballast input terminals, the measurement of luminous 
flux is made with the black cap installed, if so designed, and is made 
with an opaque white colored cover, except for the portion normally 
located within the interior of the lamp housing.

input contact and any output contact, including required length of 
wire, does not exceed 0.3 volts for either 6.4 or 12.8 line voltage 
both at the start and completion of the test.

other required test voltages, at required temperatures, at C-D of 
Figure 22, without readjustment of trimming resistors, R (each such 
required voltage being set with the minimum required load in place). 
The required voltage tests with the maximum load are conducted without 
readjusting each corresponding power supply voltage, previously set 
with minimum bulb load.
    S14.9.3.1.1.6 A suitable high impedance measuring device connected 
to points X-Y in Figure 22 is used for measuring flash rate, percent

  inches (2 m) in overall width has the lateral angle nearest the other required side marker lamp on the same
  side of the vehicle reduced from 45[deg] by design as specified by S7.4.13.2, the photometric intensity
  measurement may be met at the lesser angle.
\(2)\ The photometric intensity values between test points must not be less than the lower specified minimum

\(1)\ Where clearance lamps or identification lamps are mounted with their axis of reference less than 750mm
  above the road surface, photometry requirements below 5[deg] down may be met at 5[deg] down rather than at the

\(2)\ The photometric intensity values between test points must not be less than the lower specified minimum
  value of the two closest adjacent test points on a horizontal or vertical line.
\(3)\ When optically combined with a stop lamp or turn signal lamp, this maximum applies on or above the
  horizontal.
\(4)\ Where clearance lamps are installed at locations other than on the front and rear due to the necessity to
  indicate the overall width of the vehicle, or for protection from damage during normal operation of the
  vehicle, they need not meet the photometric intensity requirement at any test point that is 45[deg] inboard.
