‘Illuminating surface’ (see Annex 3);

2.9.1.

2.9.2.

‘Illuminating surface of a lighting device’ (paragraphs 2.7.9, 2.7.10, 2.7.19, 2.7.21 and 2.7.26)
means the orthogonal projection of
the reflector, or in the case of
headlamps with an ellipsoidal reflector of the ‘projection lens’, on a transverse plane. If the
lighting device has no reflector, the definition of paragraph 2.9.2 shall be applied. If the light
emitting surface of the lamp extends over part only of the full aperture of the reflector, then the
projection of that part only is taken into account.

the full aperture of

In the case of a dipped-beam headlamp, the illuminating surface is limited by the apparent trace
of the cut-off on to the lens. If the reflector and lens are adjustable relative to one another, the
mean adjustment should be used;

‘Illuminating surface of a light-signalling device other than a retro-reflector’ (paragraphs 2.7.11
to 2.7.15, 2.7.18, 2.7.20 and 2.7.22 to 2.7.25) means the orthogonal projection of the lamp in
a plane perpendicular to its axis of reference and in contact with the exterior light-emitting
surface of the lamp, this projection being bounded by the edges of screens situated in this
plane, each allowing only 98 % of the total luminous intensity of the light to persist in the
direction of the axis of reference.

To determine the lower, upper and lateral limits of the illuminating surface only screens with
horizontal or vertical edges shall be used to verify the distance to the extreme edges of the
vehicle and the height above the ground.

For other applications of the illuminating surface, e.g. distance between two lamps or functions,
the shape of the periphery of this illuminating surface shall be used. The screens shall remain
parallel, but other orientations are allowed to be used.

In the case of a light-signalling device whose illuminating surface encloses either totally or
partially the illuminating surface of another function or encloses a non-lighted surface, the
illuminating surface may be considered to be the light emitting surface itself.

2.9.3.

‘Illuminating surface of a retro-reflector’ (paragraph 2.7.16) means, as declared by the applicant
during the component approval procedure for the retro-reflectors, the orthogonal projection of
a retro-reflector in a plane perpendicular to its axis of reference and delimited by planes
contiguous to the declared outermost parts of the retro-reflectors’ optical system and parallel
to that axis. For the purposes of determining the lower, upper and lateral edges of the device,
only horizontal and vertical planes shall be considered.

2.10.

The ‘apparent surface’ for a defined direction of observation means, at the request of the
manufacturer or his duly accredited representative, the orthogonal projection of:

either the boundary of the illuminating surface projected on the exterior surface of the lens (a-
b);

or the light-emitting surface (c-d);

in a plane perpendicular to the direction of observation and tangential to the most exterior
point of the lens (see Annex 3 to this Regulation).

‘Axis of reference’ (or ‘reference axis’) means the characteristic axis of the lamp determined by
the manufacturer (of the lamp) for use as the direction of reference (H = 0°, V = 0°) for angles
of field for photometric measurements and for installing the lamp on the vehicle;

‘Centre of reference’ means the intersection of the axis of reference with the exterior light-
emitting surface; it is specified by the manufacturer of the lamp;

2.12.

30.5.2007

EN

Official Journal of the European Union

L 137/7

2.13.

‘Angles of geometric visibility’ means the angles which determine the field of the minimum
solid angle in which the apparent surface of the lamp must be visible. That field of the solid
angle is determined by the segments of the sphere of which the centre coincides with the centre
of reference of the lamp and the equator is parallel with the ground. These segments are
determined in relation to the axis of reference. The horizontal angles ß correspond to the
longitude and the vertical angles α to the latitude. There must be no obstacle on the inside
of the angles of geometric visibility to the propagation of light from any part of the apparent
surface of the lamp observed from infinity.

If measurements are taken closer to the lamp, the direction of observation must be shifted
parallel to achieve the same accuracy.

On the inside of the angles of geometric visibility no account is taken of obstacles, if they were
already presented when the lamp was type-approved.

If, when the lamp is installed, any part of the apparent surface of the lamp is hidden by any
further parts of the vehicle, proof shall be furnished that the part of the lamp not hidden by
obstacles still conforms to the photometric values prescribed for the approval of the device as
an optical unit (see Annex 3 of this Regulation). Nevertheless, when the vertical angle of
geometric visibility below the horizontal may be reduced to 5° (lamp at less than 750 mm
above the ground) the photometric field of measurements of the installed optical unit may be
reduced to 5° below the horizontal.

2.14.

‘Extreme outer edge’ on either side of the vehicle, means the plane parallel to the median
longitudinal plane of the vehicle and touching its lateral outer edge, disregarding the projection:

2.14.1.

of tyres near their point of contact with the ground, and of connections for tyre-pressure
gauges;

2.14.2.

of any anti-skid devices mounted on the wheels;

2.14.3.

of rear-view mirrors;

2.14.4.

of side direction-indicator lamps, end-outline marker lamps, front and rear position lamps,
parking lamps, retro-reflectors and side-marker lamps;

2.14.5.

of customs seals affixed to the vehicle, and of devices for securing and protecting such seals.

2.15.

‘Overall width’ means the distance between the two vertical planes defined in paragraph 2.14.
above;

2.16.

‘Single and multiple lamps’

2.16.1.

‘A single lamp’ means:

(a) a device or part of a device having one lighting or light-signalling function, one or more
light source(s) and one apparent surface in the direction of the reference axis, which may be
a continuous surface or composed of two or more distinct parts, or

(b) any assembly of

lamps, whether identical or not, having the same
two independent
function, both approved as type ‘D’
lamp and installed so that the projection of their
apparent surfaces in the direction of the reference axis occupies not less than 60 % of
the smallest quadrilateral circumscribing the projections of the said apparent surfaces in the
direction of the reference axis.

2.16.2.

‘Two lamps’ or ‘an even number of lamps’, means a single light-emitting surface in the shape of
a band or strip if such band or strip is placed symmetrically in relation to the median long-
itudinal plane of the vehicle, extends on both sides to within at least 0,4 m of the extreme outer
edge of the vehicle, and is not less than 0,8 m long; the illumination of such surface shall be
provided by not less than two light sources placed as close as possible to its ends; the light-
emitting surface may be constituted by a number of juxtaposed elements on condition that the
projections of the several individual light-emitting surfaces on a transverse plane occupy not
less than 60 % of the area of the smallest rectangle circumscribing the projections of the said
individual light-emitting surfaces;

2.18.

2.19.

2.20.

2.21.

2.22.

2.23.

‘Distance between two lamps’ which face in the same direction means the shortest distance
between the two apparent surfaces in the direction of the reference axis. Where the distance
between the lamps clearly meets the requirements of the Regulation, the exact edges of apparent
surfaces need not be determined;

‘Operating tell-tale’ means a visual or auditory signal (or any equivalent signal) indicating that a
device has been switched on and is operating correctly or not;

‘Closed-circuit tell-tale’ means a visual (or any equivalent signal) indicating that a device has
been switched on, but not indicating whether it is operating correctly or not;

Either the total area of the projection of the distinct parts on a plane tangent to the exterior
surface of the transparent material and perpendicular to the reference axis shall occupy not less
than 60 % of the smallest quadrilateral circumscribing the said projection, or the distance
between two adjacent/tangential distinct parts shall not exceed 15 mm when measured perpen-
dicularly to the reference axis.

5.8.

The maximum height above the ground shall be measured from the highest point and the
minimum height from the lowest point of the apparent surface in the direction of the reference
axis.

In the case of dipped-beam headlamp, the minimum height in relation to the ground is
measured from the lowest point of the effective outlet of the optical system (e.g. reflector,
lens, projection lens) independent of its utilisation.

Where the (maximum and minimum) height above the ground clearly meets the requirements
of the Regulation, the exact edges of any surface need not be determined.

The position, as regards width, will be determined from that edge of the apparent surface in the
direction of the reference axis which is the furthest from the median longitudinal plane of the
vehicle when referred to the overall width, and from the inner edges of the apparent surface in
the direction of the reference axis when referred to the distance between lamps.

Where the position, as regards width, clearly meets the requirements of the Regulation, the
exact edges of any surface need not be determined.

No red light which could give rise to confusion shall be emitted from a lamp as defined in
paragraph 2.7 in a forward direction and no white light which could give rise to confusion,
other than from the reversing lamp, shall be emitted from a lamp as defined in paragraph 2.7
in a rearward direction. No account shall be taken of lighting devices fitted for the interior
lighting of the vehicle. In case of doubt, this requirement shall be verified as follows:

For the visibility of red light towards the front of a vehicle, with the exception of a red rearmost
side-marker lamp, there must be no direct visibility of the apparent surface of a red lamp if
viewed by an observer moving within Zone 1 as specified in Annex 4.

For the visibility of white light towards the rear, there must be no direct visibility of the
apparent surface of a white lamp if viewed by an observer moving within Zone 2 in a
transverse plane situated 25 m behind the vehicle (see Annex 4);

5.10.3.

In their respective planes, the zones 1 and 2 explored by the eye of the observer are bounded:

5.10.3.1.

in height, by two horizontal planes 1 m and 2,2 m respectively above the ground;

5.10.3.2.

in width, by two vertical planes which, forming to the front and to the rear respectively an
angle of 15° outwards from the vehicle's median longitudinal plane, pass through the point or
points of contact of vertical planes parallel to the vehicle's median longitudinal plane delimiting
the vehicle's overall width; if there are several points of contact, the foremost shall correspond
to the forward plane and the rearmost to the rearward plane.

5.12.

The electrical connections must be such that the front and rear position lamps, the end-outline
marker lamps, if they exist, the side-marker lamps, if they exist, and the rear registration plate
lamp can only be switched on and off simultaneously. This condition does not apply when
using front and rear position lamps, as well as side-marker lamps when combined or reci-
procally incorporated with said lamps, as parking lamps and when side-marker lamps are
permitted to flash.

The electrical connections must be such that the main-beam and dipped-beam headlamps and
the front fog lamps cannot be switched on unless the lamps referred to in paragraph 5.11 are
also switched on. This requirement shall not apply, however, to main-beam or dipped-beam
headlamps when their luminous warnings consist of the intermittent lighting up at short
intervals of the main-beam headlamp or the intermittent lighting up at short intervals of the
dipped-beam headlamp or the alternate lighting up at short intervals of the main-beam and
dipped beam headlamps.

The concealment of lamps shall be prohibited, with the exception of the main-beam headlamps,
the dipped-beam headlamps and the front fog lamps, which may be concealed when they are
not in use.

In the event of any failure affecting the operation of the concealment device(s) the lamps shall
remain in the position of use, if already in use, or shall be capable of being moved into the
position of use without the aid of tools.

It must be possible to move the lamps into the position of use and to switch them on by
means of a single control, without excluding the possibility of moving them into the position of
use without switching them on. However, in the case of grouped main-beam and dipped-beam
headlamps,

paragraphs 5.18, 5.19 and 5.20 are fulfilled.

Rear position lamps, rear direction-indicators and rear retro-reflectors, triangular as well as
non triangular, may be installed on movable components only:

if at all fixed positions of the movable components the lamps on the movable components
meet all the position, geometric visibility and photometric requirements for those lamps.
Should the above functions be obtained by an assembly of two lamps marked ‘D’
(see
paragraph 2.16.1) only one of these lamps needs to meet the above-mentioned requirements;

or

where additional lamps for the above functions are fitted and are activated, when the movable
component is in any fixed open position, provided that these additional lamps satisfy all the
position, geometric visibility and photometric requirements applicable to the lamps installed
on the movable component.

devices installed on them shall not cause undue discomfort to road users.

fog lamps,

When a lamp is installed on a movable component and the movable component is in the
‘normal position(s) of use’, the lamp must always return to the position(s) specified by the
manufacturer in accordance with this Regulation. In the case of dipped-beam headlamps and
front
this requirement shall be considered satisfied if, when the movable
components are moved and returned to the normal position 10 times, no value of the
angular inclination of these lamps, relative to its support, measured after each operation of
the movable component, differs by more than 0,15 % from the average of the 10 measured
values. If this value is exceeded each limit specified in paragraph 6.2.6.1.1 shall then be
modified by this excess to decrease the allowed range of inclinations when checking the
vehicle according to Annex 6.

The apparent surface in the direction of the reference axis of front and rear position lamps,
front and rear direction-indicator lamps and retro-reflectors shall not be hidden more than
50 % by any movable component, with or without a light-signalling device installed on it, in
any fixed position different from the ‘normal position of use’.

If the above requirement is not practicable:

Lamps shall be fitted in a vehicle in such a way that the light source can be correctly replaced
according to the instructions of the vehicle manufacturer without the use of special tools,
other than those provided with the vehicle by the manufacturer. This requirement is not
applicable to:

(a) devices approved with a non-replaceable light source;

(b) devices approved with light sources according to Regulation No 99.

Any temporary fail-safe replacement of the light-signalling function of a rear position lamp is
allowed, provided that the substituting function in case of a failure is similar in colour, main
intensity and position to the function that has ceased to operate and provided that the
substituting device remains operational in its original safety function. During substitution, a

MEASUREMENT OF THE VARIATION OF DIPPED-BEAM INCLINATION AS A FUNCTION OF LOAD

ANNEX 6

1.

SCOPE

This annex specifies a method for measuring variations in motor vehicle dipped-beam inclination, in relation to
its initial inclination, caused by changes in vehicle attitude due to loading.

2.

DEFINITIONS

2.1.

Initial inclination

2.1.1.

Stated initial inclination

The value of the dipped-beam initial
reference value for the calculation of permissible variations.

inclination specified by the motor vehicle manufacturer serving as a

2.1.2. Measured initial inclination

The mean value of dipped-beam inclination or vehicle inclination measured with the vehicle in condition No 1,
as defined in Annex 5, for the category of vehicle under test. It serves as a reference value for the assessment of
variations in beam inclination as the load varies.

2.2.

Dipped-beam inclination

It may be defined as follows:

either as the angle, expressed in milliradians, between the direction of the beam towards a characteristic point on
the horizontal part of the cut-off in the luminous distribution of the headlamp and the horizontal plane,

or by the tangent of that angle, expressed in percentage inclination, since the angles are small (for these small
angles, 1 % is equal to 10 mrad).

If the inclination is expressed in percentage inclination, it can be calculated by means of the following formula:

ðh1 – h2Þ
L

× 100

where:

h1

h2

is the height above the ground, in millimetres, of the above mentioned characteristic point, measured on a
vertical screen perpendicular to the vehicle longitudinal median plane, placed at a horizontal distance L.

is the height above the ground, in millimetres, of the centre of reference (which is taken to be the nominal
origin of the characteristic point chosen in h1):

L

is the distance, in millimetres, from the screen to the centre of reference.

Negative values denote downward inclination (see figure 1).

Positive values denote upward inclination.

Official Journal of the European Union

30.5.2007

Notes:

1. This drawing represents a category M1 vehicle, but the principle shown applies equally to vehicles of other

categories.

2. Where the vehicle does not incorporate a headlamp levelling system, the variation in dipped-beam inclination

is identical with the variation in the inclination of the vehicle itself.

3.

MEASUREMENT CONDITIONS

3.1.

3.2.

3.3.

If a visual inspection of the dipped-beam pattern on the screen or a photometric method is used, measurement
shall be carried out in a dark environment (for example, a dark room) of sufficient area to allow the vehicle and
the screen to be placed as shown in figure 1. Headlamp centres of reference shall be at a distance from the
screen of at least 10 m.

The ground on which measurements are made shall be as flat and horizontal as possible, so that the repro-
ducibility of measurements of dipped-beam inclination can be assured with an accuracy of ± 0,5 mrad (± 0,05 %
inclination).

If a screen is used, its marking, position and orientation in relation to the ground and to the median longitudinal
plane of the vehicle, shall be such that the reproducibility of the measurement of the dipped-beam inclination
can be assured with an accuracy of ± 0,5 mrad (± 0,05 % inclination).

3.4.

During measurements, the ambient temperature shall be between 10 and 30 °C.

4.

VEHICLE PREPARATION

4.1.

4.2.

Measurements shall be carried out on a vehicle which has travelled a distance of between 1 000 km and 10 000
km, preferably 5 000 km.

Tyres shall be inflated to the full-load pressure specified by the vehicle manufacturer. The vehicle shall be fully
replenished (fuel, water, oil) and equipped with all the accessories and tools specified by the manufacturer. Full
fuel replenishment means that the fuel tank must be filled to not less than 90 % of its capacity.

4.3.

The vehicle shall have the parking brake released and the gearbox in neutral.

4.4.

The vehicle shall be conditioned for at least 8 h at the temperature specified in paragraph 3.4.

4.5.

If a photometric or visual method is used, headlamps with a well-defined dipped-beam cut-off should preferably
be installed on the vehicle under test in order to facilitate the measurements. Other means are allowed to obtain
a more precise reading (for example, removal of the headlamp lens).

5.

TEST PROCEDURE

5.1.

General

The variations in either dipped-beam or vehicle inclination, depending on the method chosen, shall be measured
separately for each side of the vehicle. The results obtained from both left and right headlamps under all the load
conditions specified in Annex 5, shall be within the limits set out in paragraph 5.5. The load shall be applied
gradually without subjecting the vehicle to excessive shocks.

5.2.

Determination of the measured initial inclination

The vehicle shall be prepared as specified in paragraph 4 and laden as specified in Annex 5 (first loading
the vehicle shall be rocked as
condition of
specified in paragraph 5.4. Measurements shall be made three times.

the respective vehicle category). Before each measurement,

5.2.1.

If none of the three measured results differ by more than 2 mrad (0,2 % inclination) from the arithmetic mean of
the results, that mean shall constitute the final result.

30.5.2007

EN

Official Journal of the European Union

L 137/59

5.2.2.

If any measurement differs from the arithmetic mean of the results by more than 2 mrad (0,2 % inclination), a
further series of 10 measurements shall be made, the arithmetic mean of which shall constitute the final result.

5.3.

Measurement methods

Any method may be used to measure variations of inclination provided that the readings are accurate to within
± 0,2 mrad (± 0,02 % inclination).

5.4.

Treatment of vehicle in each loading condition

The vehicle suspension and any other part likely to affect dipped-beam inclination shall be activated according to
the methods described below.

However, the technical authorities and manufacturers may jointly propose other methods (either experimental or
based upon calculations), especially when the test poses particular problems, provided such calculations are
clearly valid.

5.4.1. M1 category vehicles with conventional suspension

With the vehicle standing on the measuring site and, if necessary, with the wheels resting on floating platforms
(which must be used if their absence would lead to restriction of the suspension movement likely to affect the
results of measurements), rock the vehicle continuously for at least three complete cycles, for each cycle, first the
rear and than the front end of the vehicle is pushed down.

The rocking sequence shall end with the completion of a cycle. Before making the measurements, the vehicle
shall be allowed to come to rest spontaneously. Instead of using floating platforms, the same effect can be
achieved by moving the vehicle backwards and forwards for at least a complete wheel revolution.

5.4.2. M2, M3 and N category vehicles with conventional suspension

5.4.2.1. If the treatment method for category M1 vehicles described in paragraph 5.4.1 is not possible, the method

described in paragraphs 5.4.2.2 or 5.4.2.3 may be used.

5.4.2.2. With the vehicle standing on the measuring site and the wheels on the ground, rock the vehicle by temporarily

varying the load.

5.4.2.3. With the vehicle standing on the measuring site and the wheels on the ground, activate the vehicle suspension
and all other parts which may affect the dipped-beam inclination by using a vibration rig. This can be a vibrating
platform on which the wheels rest.

5.4.3.

Vehicles with non-conventional suspension, where the engine has to be running

Before making any measurement wait until the vehicle has assumed its final attitude with the engine running.

5.5.

Measurements

The variation of the inclination of the dipped-beam shall be assessed for each of the different loading conditions
in relation to the measured initial inclination determined in accordance with paragraph 5.2.

If the vehicle is fitted with a manual headlamp-levelling system, the latter shall be adjusted to the positions
specified by the manufacturer for given loading conditions (according to Annex 5).

5.5.1.

To begin with, a single measurement shall be made in each loading condition. Requirements have been met if,
for all the loading conditions, the variation in inclination is within the calculated limits (for example, within the
difference between the stated initial inclination and the lower and upper limits specified for approval) with a
safety margin of 4 mrad (0,4 % inclination).

5.5.2.

If the result(s) of any measurement(s) does (do) not lie within the safety margin indicated in paragraph 5.5.1 or
exceed(s) the limit values, a further three measurements shall be made in the loading conditions corresponding to
this (these) result(s) as specified in paragraph 5.5.3.

L 137/60

EN

Official Journal of the European Union

30.5.2007

5.5.3.

For each of the above loading conditions:

5.5.3.1. If none of the three measured results differs by more than 2 mrad (0,2 % inclination) from the arithmetic mean

of the results, that mean shall constitute the final result.

5.5.3.2. If any measurement differs from the arithmetic mean of the results by more than 2 mrad (0,2 % inclination), a
further series of 10 measurements shall be made, the arithmetic mean of which shall constitute the final result.

5.5.3.3. If a vehicle is fitted with an automatic headlamp-levelling system which has an inherent hysteresis loop, average

results at the top and bottom of the hysteresis loop shall be taken as significant values.

All these measurements shall be made in accordance with paragraphs 5.5.3.1 and 5.5.3.2.

5.5.4.

Requirements have been met,

inclination determined in accordance with paragraph 5.2 and the inclination measured under each loading
condition is less than the values calculated in paragraph 5.5.1 (without safety margin).

If only one of the calculated upper or lower limits of variation is exceeded, the manufacturer shall be permitted
to choose a different value for the stated initial inclination, within the limits specified for approval.

installed to the left or below the button(s) for other dipped-beam positions.

A rotary control which is installed edge-on, or with only the edge visible, should follow the operating principles of
control of types (a) or (c).

1.1.1. This control must carry symbols indicating clearly the movements corresponding to the downward and upward

inclination of the dipped-beam.

1.2.

The ‘0’ position corresponds to the initial inclination according to paragraph 6.2.6.1.1. of this Regulation.

1.3.

The ‘0’ position which, according to paragraph 6.2.6.2.2. of this Regulation has to be a ‘stop position’, need not
necessarily be at the end of the scale.

1.4.

The marks used on control must be explained in the owner's handbook.

1.5. Only the following symbols may be used to identify the controls:

TESTS

1.1.

Position of lamps

The position of lamps, as defined in paragraph 2.7 of this Regulation, in width, in height and in length shall be
checked in accordance with the general requirements set out in paragraphs 2.8 to 2.10, 2.14 and 5.4 of this
Regulation.

The values measured for the distances shall be such that the individual specifications applicable to each lamp
are fulfilled.

1.2.

Visibility of lamps

1.2.1.

The angles of geometric visibility shall be checked in accordance with paragraph 2.13 of this Regulation.

The values measured for the angles shall be such that the individual specifications applicable to each lamp are
fulfilled except that the limits of the angles may have an allowance corresponding to the ± 3° variation
permitted in paragraph 5.3. for the mounting of the light-signalling devices.

1.2.2.

The visibility of red light towards the front and of white light towards the rear shall be checked in accordance
with paragraph 5.10 of this Regulation.

1.3.

Alignment of dipped-beam headlamps towards the front

1.3.1.

Initial downward inclination

The initial downward inclination of the cut-off of the dipped beam shall be set to the plated figure as required
and shown in Annex 7.

Alternatively the manufacturer shall set the initial aim to a figure that is different from the plated figure where
it can be shown to be representative of the type approved when tested in accordance with the procedures
contained in Annex 6 and in particular paragraph 4.1.

1.3.2.

Variation of inclination with load

The variation of the dipped-beam downward inclination as a function of the loading conditions specified
within this section shall remain within the range:

0,2 % to 2,8 % for headlamp mounting height h < 0,8;
0,2 % to 2,8 % for headlamp mounting height 0,8 ≤ h ≤ 1,0; or

0,7 % to 3,3 % (according to the aiming range chosen by the manufacturer at the approval);
0,7 % to 3,3 % for headlamp mounting height 1,0 < h ≤ 1,2 m;

1,2 % to 3,8 % for headlamp mounting height h > 1,2 m.

The states of loading to be used shall be as follows, as indicated in Annex 5 to this Regulation, for every
system adjusted accordingly.

Electrical connections and telltales

The electrical connections shall be checked by switching on every lamp supplied by the electrical system of the
vehicle.

The lamps and telltales shall function in accordance with the provisions set out in paragraphs 5.11 to 5.14 of
this Regulation and with the individual specifications applicable to each lamp.

1.5.

Light intensities

1.5.1.

Main-beam headlamps

The aggregate maximum intensity of the main beam headlamps shall be checked by the procedure described in
paragraph 6.1.9.2 to this Regulation. The value obtained shall be such that the requirement in paragraph
6.1.9.1 of this Regulation is fulfilled.

1.6.

The presence, number, colour, arrangement and, where applicable, the category of lamps shall be checked by
visual inspection of the lamps and their markings.

These shall be such that the requirements set out in paragraphs 5.15 and 5.16 as well as in the individual
specifications applicable to each lamp are fulfilled.
