Replaceable Light Source Information;

and Associated Equipment

AGENCY: National Highway Traffic

Safety Administration (NHTSA), DOT.

ACTION: Final rule.

SUMMARY: This document amends the

Federal motor vehicle safety standard

on lighting to allow high intensity

discharge (HID) light sources to be used

in replaceable bulb headlamp systems,

in addition to their presently allowed

use in integral beam headlamp systems.

Adoption of this amendment requires

corresponding amendments to part 564,

the regulation under which Docket No.

93–11 was established as a depository

for replaceable light source information.

However, if the life of the light source

approaches that of the vehicle, as is the

case with HIDs, interchangeability will

no longer be so important. Therefore,

NHTSA is adding Appendix B to part

564 which allows a manufacturer to

submit fewer items of dimensional

information if it can demonstrate that

the rated laboratory life of its light

source is not less than 2,000 hours.

DATES: Effective Date: The amendments

to the Code of Federal Regulations, and

the requirements of the amendments,

are effective June 6, 1996.

Petition Date: Petitions for

reconsideration must be received not

later than June 21, 1996.

FOR FURTHER INFORMATION CONTACT:

Kenneth O. Hardie, Office of

Rulemaking (202–366–6987).

SUPPLEMENTARY INFORMATION: On June

19, 1995, NHTSA published a notice in

the Federal Register to initiate

rulemaking that would amend Standard

No. 108 so as to allow replaceable bulb

headlamps to incorporate short arc

discharge light sources (60 FR 31939).

As NHTSA noted in the NPRM, short

arc discharge headlamp systems are

commonly referred to as ‘‘high intensity

discharge’’ (HID) systems. Presently, the

only HID application in production for

lamps covered by Standard No. 108 is

in headlamps, and the only way HID

headlamps can be used under Standard

No. 108 is in an ‘‘integral beam

headlighting system’’ (Section S7.4).

Thus, today, HID headlamps are

comprised of a headlamp body

(including reflector and lens), a small

transparent envelope containing a

specific mixture of gases under high

pressure (the discharge bulb), and an

electronic ballast to convert low voltage

direct current to a controlled output

high voltage direct or alternating current

to drive the discharge bulb.

However, by definition (S4), an

integral beam headlamp (including

those with HID light sources) is one

with an ‘‘integral and indivisible optical

assembly’’, and a headlamp that is ‘‘not

a replaceable bulb headlamp * * *.’’ In

the event of damage to one component,

such as the lens, the entire unit, ballast

and all, must be replaced. The cost to

replace an integral beam HID headlamp

is substantially higher than the cost of

replacing a more conventional

headlamp. The initial HID headlamp

permitted (as a result of NHTSAinitiated amendments to Standard No.

108 to facilitate their introduction) was

an integral-type design. At the time, it

was unknown how to define HID

sources as replaceable bulb light

sources. The agency is now furthering

HID headlamp technology by defining

HID’s as ‘‘replaceable light sources’’, so

that headlamp components may be

individually replaced. This amendment

to Standard No. 108 means that a

vehicle manufacturer wishing to offer

HID headlamps now has a choice

between two types, integral and

replaceable light source.

Comments in support of the NPRM

were received from the American

Automobile Manufacturers Association

(AAMA), Ford Motor Co., Hella, Inc.,

Koito Manufacturing Co. Ltd., OSRAM

Sylvania, Inc. (OSI), and Stanley

Electronic Co., Inc. Comments opposing

the proposal were received from the

Insurance Institute for Highway Safety

(IIHS) and Advocates for Highway and

Auto Safety (Advocates).

Proposed Amendments to Standard No.

108

S4 Definitions. NHTSA proposed to

add a definition of ‘‘filament’’ to read:

Filament means that part of the light

source or light emitting element(s), such as

a resistive element, the excited portion of a

specific mixture of gases under pressure, or

any part of other energy conversion sources,

that generates radiant energy which can be

seen.

No comments were received on this

issue and the proposed definition is

adopted.

Paragraph S7.7(i). The NPRM

proposed amendments to paragraph

S7.7(i). Under the final rule published

on November 28, 1995 (60 FR 58522),

transferring HB type light sources to

part 564, paragraph S7.7(i) became

paragraph S7.7(b). Under the final rule

published today, paragraph S7.7(b)

becomes S7.7(d). The following

summary of the proposal adopts the

nomenclature of the final rule, which

does not significantly differ from the

proposal.

Paragraph S7.7(d) discusses the

procedures for measuring maximum

power and luminous flux. This is

followed by two new subparagraphs, the

first of which, S7.7(d)(1), applies

specifically to seasoning requirements

for light sources with resistive element

type filaments and luminous flux

measurement requirements for HB Type

bulbs. The second, S7.7(d)(2), applies to

seasoning requirements for light sources

using excited gas mixtures as filaments

or discharge arcs and associated

luminous flux measurement. As for

seasoning of light sources using other

energy conversion sources, NHTSA will

address this issue when industry has

identified such sources.

OSI recommended that the seasoning

for resistive and excited-gas light

sources (including ballasts) should be

one percent of rated life, as set forth in

SAE Recommended Practice J2009

FEB93 Discharge Forward Lighting

Systems (hereafter ‘‘SAE J2009’’). Ford

also recommended that seasoning for

excited gas light sources (including

ballast) be in accordance with SAE

J2009. Additionally, Ford recommended

that seasoning for resistive element type

filaments be in accordance with SAE

J1383 APR85. NHTSA notes that its

proposed amendments affecting

‘‘seasoning’’ are consistent with the OSI

and Ford recommendations.

Ford found proposed paragraph

S7.7(i) confusing and it suggested

changes which it felt would clarify

NHTSA’s intent. NHTSA concurs, and

has rewritten the provision as S7.7(b)

(In addition to recommending specific
20498 Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

requirements for the measurement of

luminous flux for a light source with a

resistive element type filament, Ford

did not object to the NHTSA proposal

to specifically cite seasoning

requirements for light sources using an

excited gas mixture).

Regarding proposed paragraph

S7.7(l)(7) which would require the date

of manufacture to be placed on the light

source, Ford asked that it not be

adopted as it provides no safety benefit

and because Standard No. 108 does not

require date of manufacture marking for

any other lamps or lighting equipment.

NHTSA concurs, and the proposal is not

adopted.

Readers should note that proposed

new paragraph S7.7(l) is adopted as

paragraph S7.7(e). New section S7.7(f) is

added to state that, for light sources that

use light generated by gaseous discharge

lighting sources, seasoning shall be in

accordance with section 4.0, and the

‘‘rated laboratory life’’ shall be

determined in accordance with sections

4.3 and 4.9 of SAE J2009.

S8 Tests and Procedures for Integral

Beam and Replaceable Bulb

Headlighting Systems. In the NPRM,

NHTSA proposed adding ‘‘specific gas

mixture’’ type light sources in the tests

specified in S8 to replace ‘‘non-filament

type.’’ There was no objection and S8 is

amended as proposed.

Other Issues Associated with Short

Arc Discharge Lighting Systems. The

only regulatory requirement that

NHTSA proposed that addressed the

issue of electrical shock was the

marking of the ballast with an

appropriate warning. Stanley

recommended the adoption of a

universally agreed upon marking system

such as specified by the International

Standards Organization (ISO). However,

NHTSA wishes to allow manufacturers

wide latitude in choosing their warnings

regarding electrical shock and has not

followed Stanley’s suggestion in the

final rule.

Proposed Amendments to Part 564

General. Ford would replace all

references to ‘‘filament’’ with ‘‘filament

or discharge arc.’’ NHTSA agrees, and

this has been done when the text could

specifically refer to either. Also as

indicated previously, the definition of

‘‘filament’’ that was proposed to be

added to Standard No. 108, and it

applies to part 564 by virtue of Section

564.4 which incorporates definitions

used in other NHTSA regulations.

Section 564.2 Purpose. Ford

recommended that this section not be

revised because both Appendix A and

Appendix B have a common purpose;

‘‘they merely accomplish it by requiring

varying degrees of information detail

dependent upon the rated laboratory life

of the light source.’’ NHTSA disagrees;

the intended purposes of Appendix A

and Appendix B are different. One

purpose of the former is to assure that

replacement light sources are available

and interchangeable. This is not a

purpose of Appendix B because longlife light sources need not be

manufactured for interchangeability

purposes by many different aftermarket

suppliers. Because light sources with

specifications filed under Appendix B

are expected to last the life of the

vehicle, component replacement would

be necessitated primarily by damage.

Thus it is unlikely that the low demand

for replacement components would be

met by other than manufacturers of the

original equipment devices. This

distinction from Appendix A requires

two different statements of regulatory

purposes in section 564.2.

Finally, Appendix B allows

manufacturers to retain ballast design

parameters that may include proprietary

manufacturing specifications, whereas

Appendix A requires disclosure of such

aspects as they relate to

interchangeability.

Paragraph 564.5(a). Under the

proposal, relevant manufacturers must

‘‘furnish the information specified in

appendix A or appendix B.’’ Ford

suggested that this implied that

manufacturers could file under either

Appendix when filing under Appendix

B is allowable only for long-life light

sources. NHTSA has made an editorial

change to clarify that Appendix B is

available only for long-life light sources,

while both Appendices are available for

long- life light source information.

Appendix B. Commenters concurred

with NHTSA’s proposed benchmark

that not less than 2,000 hours of rated

laboratory life is a suitable designation

of a long-life light source. In accordance

with the proposal, in the final rule the

manufacturer of such a light source may

provide the lesser amount of

information that will be required by

Appendix B, but, at its option, can make

its submission under Appendix A. In

either event, a replaceable light source

which is the subject of information

submitted to Docket No. 93–11 is

required to comply with Standard No.

108.

Stanley commented that a clear

definition of ‘‘life’’ was not provided in

the NPRM, and recommended that

‘‘life’’ of a light source be defined in

terms of luminous flux maintenance.

NHTSA concurs that an explanation is

desirable, since Standard No. 108 and

Part 564 both indicate that

manufacturers may optionally furnish

the information specified in Appendix

B, if the ‘‘rated average laboratory life’’

is not less than 2,000 hours. The SAE

has addressed this issue in sections 4.3

and 4.9 of SAE J2009. These sections

specify procedures and tests to

determine life of the total HID system

measured in both hours and starting

cycles. NHTSA is adopting the term

used there, ‘‘rated laboratory life.’’ In so

doing, it also examined the definition of

‘‘rated average laboratory life’’ which

appears in SAE Standard J1383 JUN90.

It found that SAE J1383 JUN90 was

suitable for incandescent light sources

where lumen drop off occurs at a

relatively steady rate over life, but that

HID system lumens drop rapidly during

the initial burning hours and then, later,

tend toward a more level rate of drop.

In Koito’s view, Appendix B is not

necessary. It believes that all light

source submittals to part 564, including

HIDs, and regardless of the rated

laboratory life, should contain the

information required in Appendix A. It

indicated that the life in hours of an HID

light source will vary with the ballasts

combined with it. Therefore, life in

hours for an HID light source is

essentially meaningless if the original

ballast is changed to another type of

ballast. NHTSA understands this. It is

for this reason that NHTSA is adopting

the language proposed in the NPRM that

Item III of Appendix B specifies the

rated laboratory life of the light source/

ballast combination instead of that of

the light source alone. Item IV of

Appendix B of this final rule reflects

this requirement. Appendix B was

specifically intended to accommodate

all ballasts that are functionally

interchangeable with a light source but

different in design. New paragraph

S7.7(e)(4) of Standard No. 108, adopted

in this final rule, requires that each

ballast filed with a light source bear

permanent markings that indicate the

rated laboratory life of the combination.

Any part 564 submittal for a light source

requiring ballasts for operation must

include information that specifically

identifies all ballasts that will be used

with the light source. Substitution of a

ballast other than that identified with

the light source in part 564 is not

permitted.

It is important that ballast information

be submitted. NHTSA considers the

electronic ballast along with the

transparent envelope containing a

specific mixture of gases under pressure

(the discharge bulb) to be an integral

part of the light source system, although

the bulb and ballast may be separate

components. Furthermore, in

determining compliance with Standard

No. 108, testing of the light source
Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations 20499

without a designated ballast would be

difficult if not impossible.

NHTSA has decided not to act upon

Koito’s recommendation that all light

source submittals (including HID) be

required to fulfill all informational

requirements of Appendix A. The intent

of Appendix A is to ensure that

sufficient technical information is

available to replacement light source

manufacturers so that they may

manufacture identical replacement light

sources. NHTSA has decided that

requiring the Appendix B submitter to

provide all the information required in

Appendix A is unnecessary if the

manufacturer provides rated laboratory

life data supporting a light source and

ballast life of 2,000 hours or more.

Ford recommended that Section I of

Appendix A be added to Appendix B

(‘‘Filament Position Dimensions and

Tolerances Using Either Direct Filament

Dimensions or the Three Dimensional

Filament Tolerance Box’’). Ford also

recommended that Appendix B require

specification of the electrode position

dimensions and tolerances for light

sources using excited gas mixtures as

filaments. Ford stated that the mid-point

of the electrode separation distance

would provide a comparable dimension

‘‘A’’ of Figure 8 to be utilized in

Standard No. 108’s section S9 Deflection

test for replaceable light sources.

NHTSA concurs with this

recommendation since, as Ford stated,

the mid-point of the electrode

separation distance would provide a

comparable dimension ‘‘A’’ which is

required to support the bulb deflection

test for replaceable light sources (S9).

NHTSA has accordingly amended

Section I of Appendix B as adopted.

Finally, the reader should note that

the conforming amendments to

paragraphs 564.5(a) and (c) reflect the

agency’s recent amendment of

paragraph S7.7 of Standard No. 108 and

564.5(a) and (c) to transfer HB type

replaceable light sources to Docket No.

93–11 (November 28, 1995; 60 FR

58522).

Comments in Opposition

IIHS opposed the rulemaking action

because HID light sources are more

expensive to replace than other light

sources and recommended that the

agency not permit the use of

increasingly expensive lighting systems

on motor vehicles without conducting a

parallel rulemaking to reinstate a nodamage 5 mph bumper standard.

Advocates, too, believed that the

replacement cost for HID headlamp

systems ought to be a central

consideration of this rulemaking.

NHTSA notes that HID light sources are

permitted in integral beam lighting

systems, and will continue to be so used

even if they are not permitted in

replaceable bulb systems. However, the

proposal to allow them in such systems

is being adopted because there are no

safety disbenefits in allowing them. The

use of replaceable light source HID

lighting systems as an alternative to

non-replaceable ones or to resistive

element type filament lighting systems

is an issue of the marketplace, not of

safety.

Advocates disagreed with NHTSA

that this rulemaking would reduce costs

both to manufacturers and consumers.

In its view, NHTSA’s rationale for cost

reduction is based upon the fact that

HID headlamps might not have to be

replaced for the life of the vehicle and

consequently is not an adequate

evaluation of the costs and benefits

accruing to consumers from the

institution of HID headlamp systems.

NHTSA’s rationale for cost reduction

is intended in the context of HID

headlamp systems. In an integral beam

system using HIDs, all headlamp parts

must be replaced when a component

fails or is damaged, even for something

as simple as a cracked lens. Allowing

HID’s to be used in replaceable bulb

headlamp systems would permit

separability and the replacement of

individual components at significant

cost savings to the consumer. Repair

costs for damaged HID headlamps ought

to be significantly reduced if lamp

bodies, discharge bulbs and ballasts can

be individually serviced, instead of

being replaced as part of a headlamp

assembly. In addition, it is probable that

minor damage would be repaired (such

as a cracked lens) that could degrade

headlamp performance if there is an

economic incentive not to defer

correction until required to do so, either

by failing performance or state motor

vehicle inspection.

Advocates also argued that the

rulemaking was mischaracterized as

‘‘non-significant.’’ The rulemaking is

properly characterized under DOT

policies and procedures. The final rule

prescribes an alternative, optional,

headlighting system, and results in no

additional costs or burdens upon any

regulated person or upon the public.

Finally, Advocates disagreed with the

agency’s decision not to regulate

ultraviolet radiation (UV) and electric

shock, and recommended that a

supplementary NPRM be issued

addressing the possible threat to human

health and safety through UV emissions

and high voltages.

There appears to be no current need

to do so, other than requiring a warning

marking on the ballast. NHTSA

addressed these concerns in the

preamble to the proposal (see 60 FR at

31942). In that discussion, NHTSA

noted that SAE J2009 recognizes UV

radiation and electric shock as potential

safety hazards. To address the hazard of

UV radiation, the lighting community

has developed HID bulbs that include

an additional transparent envelope

which is a UV filter. Other innovative

design solutions are being considered to

prevent UV emissions. The need for

high voltage shock safety is also

recognized by the SAE document. These

are design and testing issues for the

manufacturer. NHTSA will monitor

them and propose rulemaking if it

appears to be required for health and

safety.

Effective Date

Since the final rule does not impose

any additional burden and is intended

to afford an alternative to existing

requirements, it is hereby found that an

effective date earlier than 180 days after

issuance of the final rule is in the public

interest. The final rule (i.e., the

amendments to the Code of Federal

Regulations and the requirements

specified therein) is effective 30 days

after its publication in the Federal

Register.

Rulemaking Analyses

Executive Order 12866 and DOT

Regulatory Policies and Procedures

This rulemaking action has not been

reviewed under Executive Order 12866.

It has been determined that the

rulemaking action is not significant

under Department of Transportation

regulatory policies and procedures. The

effect of the rulemaking action is to

allow an alternative headlighting

system. It will not impose any

additional burden upon any person. The

final rule will reduce costs both to

manufacturers and consumers. Because

ballasts will no longer have to be

integral with the light source,

manufacturers may use a simpler, less

expensive connector. Consumers may

replace separate elements of an HIDreplaceable light source headlamp

system as compared with the present

regulation which requires replacement

of the whole unit. Impacts of the rule

are, therefore, so minimal as not to

warrant preparation of a full regulatory

evaluation.

Regulatory Flexibility Act

The agency has also considered the

effects of this rulemaking action in

relation to the Regulatory Flexibility

Act. I certify that this rulemaking action

would not have a significant economic
20500 Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations

effect upon a substantial number of

small entities. Motor vehicle and

lighting equipment manufacturers are

generally not small businesses within

the meaning of the Regulatory

Flexibility Act. Further, small

organizations and governmental

jurisdictions will not be significantly

affected as the price of new motor

vehicles will not be impacted.

Accordingly, no Regulatory Flexibility

Analysis has been prepared.

Executive Order 12612 (Federalism)

This action has been analyzed in

accordance with the principles and

criteria contained in Executive Order

12612 on ‘‘Federalism.’’ It has been

determined that the rulemaking action

does not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

National Environmental Policy Act

NHTSA has analyzed this rulemaking

action for purposes of the National

Environmental Policy Act. The

rulemaking action will not have a

significant effect upon the environment

as it does not affect the present method

of manufacturing motor vehicle lighting

equipment.

Civil Justice Reform

This rulemaking action will not have

any retroactive effect. Under 49 U.S.C.

30103, whenever a Federal motor

vehicle safety standard is in effect, a

state may not adopt or maintain a safety

standard applicable to the same aspect

of performance which is not identical to

the Federal standard. Under 49 U.S.C.

30163, a procedure is set forth for

judicial review of final rules

establishing, amending, or revoking

Federal motor vehicle safety standards.

That section does not require

submission of a petition for

reconsideration or other administrative

proceedings before parties may file suit

in court.

Paperwork Reduction Act

The reporting and record keeping

requirement associated with part 564

have been approved by the Office and

Management and Budget in accordance

with 44 U.S.C. chapter 35. The OMB

control number is 2127- 0563.

(a) If other than an HB Type, the light

source shall be marked with the bulb

marking designation specified for it in

compliance with Appendix A or

Appendix B of part 564 of this chapter.

The base of each HB Type shall be

marked with its HB Type designation.

Each replaceable light source shall also

be marked with the symbol DOT and

with a name or trademark in accordance

with paragraph S7.2.

(b) The measurement of maximum

power and luminous flux that is

submitted in compliance with

Appendix A or Appendix B of part 564

of this chapter shall be made in

accordance with this paragraph. The

filament or discharge arc shall be

seasoned before measurement of either.

Measurement shall be made with the

direct current test voltage regulated

within one quarter of one percent. The

test voltage shall be 12.8v. The

measurement of luminous flux shall be

in accordance with the Illuminating

Engineering Society of North America,
