‘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 full aperture 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.

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;

In case an AFS is installed:

where a lighting function is produced by two or more simultaneously operated lighting units on
a given side of the vehicle, the individual illuminating surfaces, taken together, constitute the illu-
minating surface to be considered (for example, in the figure of paragraph 6.22.4. below, the indi-
vidual illuminating surfaces of the lighting units 8, 9 and 11, regarded together and taking into
account their respective location, constitute the illuminating surface to be considered for the right
hand side of the vehicle).

2.9.2.

‘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 sur-
face of the lamp, this projection being bounded by the edges of screens situated in this plane, each
allowing only 98 per cent 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 hori-
zontal 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 par-
allel, but other orientations are allowed to be used.

In the case of a light-signalling device whose illuminating surface encloses either totally or par-
tially the illuminating surface of another function or encloses a non-lighted surface, the illumi-
nating 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 contigu-
ous 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 manu-
facturer 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);

2.11.

2.12.

2.13.

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).

Only in the case of a light-signalling device producing variable luminous intensities, its apparent
surface that may be variable as specified in paragraph 2.7.1.3. shall be considered under all con-
ditions permitted by the variable intensity control, if applicable.

‘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;

‘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 ref-
erence 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 β correspond to the longitude and the ver-
tical 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 par-
allel to achieve the same accuracy.

L 135/8

EN

Official Journal of the European Union

23.5.2008

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 fur-
ther 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 longi-
tudinal 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.

5.4.

The illuminating lamps described in paragraphs 2.7.9., 2.7.10. and 2.7.19. shall be so installed
that correct adjustment of their orientation can easily be carried out.

For all light-signalling devices, including those mounted on the side panels, the reference axis of
the lamp when fitted to the vehicle must be parallel to the bearing plane of the vehicle on the
road; in addition it must be perpendicular to the median longitudinal plane of the vehicle in the
case of side retro-reflectors and of side-marker lamps and parallel to that plane in the case of all
other signalling devices. In each direction a tolerance of ± 3° shall be allowed. In addition, any
specific instructions as regards fitting laid down by the manufacturer must be complied with.

In the absence of specific instructions, the height and orientation of the lamps shall be verified
with the vehicle unladen and placed on a flat, horizontal surface, in the condition defined in para-
graphs 2.24., 2.24.1. and 2.24.2. and, in the case where an AFS is installed, with the system in its
neutral state.

5.5.

In the absence of specific instructions lamps constituting a pair shall:

5.5.1.

5.5.2.

5.5.3.

be fitted to the vehicle symmetrically in relation to the median longitudinal plane (this estimate
to be based on the exterior geometrical form of the lamp and not on the edge of its illuminating
surface referred to in paragraph 2.9.);

be symmetrical to one another in relation to the median longitudinal plane, this requirement is
not valid with regard to the interior structure of the lamp;

satisfy the same colorimetric requirements and have substantially identical photometric charac-
teristics. This shall not apply to a matched pair of Class F3 front fog lamps.

5.5.4.

have substantially identical photometric characteristics.

5.6.

On vehicles whose external shape is asymmetrical the above requirements shall be satisfied so far
as is possible.

5.7.

Grouped, combined or reciprocally incorporated lamps

5.7.1.

5.7.1.1.

5.7.2.

5.7.2.1.

Lamps may be grouped, combined or reciprocally incorporated with one another provided that
all requirements regarding colour, position, orientation, geometric visibility, electrical connec-
tions and other requirements, if any, are fulfilled.

However, where stop lamps and direction indicator lamps are grouped, any horizontal or verti-
cal straight line passing through the projections of the apparent surfaces of these functions on a
plane perpendicular to the reference axis, shall not intersect more than two borderlines separat-
ing adjacent areas of different colour.

Where the apparent surface of a single lamp is composed of two or more distinct parts, it shall
satisfy the following requirements:

Either the total area of the projection of the distinct parts on a plane tangent to the exterior sur-
face of the transparent material and perpendicular to the reference axis shall occupy not less than
60 per cent 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 mini-
mum 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 utilization.

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.

23.5.2008

EN

Official Journal of the European Union

L 135/13

5.8.1.

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.

5.9.

In the absence of specific instructions, the photometric characteristics (e.g. intensity, colour,
apparent surface, etc.) of a lamp shall not be intentionally varied during the period of activation
of the lamp.

5.9.1.

Direction-indicator lamps, the vehicle-hazard warning signal, amber side-marker lamps comply-
ing with paragraph 6.18.7. below, and the emergency stop signal shall be flashing lamps.

5.9.2.

The photometric characteristics of any lamp may vary:

(a)

in relation to the ambient light;

(b) as a consequence of the activation of other lamps, or

(c) when the lamps is being used to provide another lighting function,

provided that any variation in the photometric characteristics is in compliance with the technical
provisions for the lamp concerned.

5.10.

5.10.1.

5.10.2.

No red light which could give rise to confusion shall be emitted from a lamp as defined in para-
graph 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 rear-
ward 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 of the vehicle, with the exception of white con-
spicuity markings fitted to the vehicle, 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.

5.11.

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 vehi-
cle’s overall width; if there are several points of contact, the foremost shall correspond to the for-
ward plane and the rearmost to the rearward plane.

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 reciprocally incor-
porated with said lamps, as parking lamps and when side-marker lamps are permitted to flash.

5.12.

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 head-
lamps 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.

Concealable lamps

5.14.1.

5.14.2.

5.14.3.

5.14.4.

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 concealement device(s) the lamps shall
remain in the position of use, if already in use, or shall be capable of being moved into the posi-
tion 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 head-
lamps, the control referred to above is required only to activate the dipped-beam headlamps.

It must not be possible deliberately, from the driver’s seat, to stop the movement of switched-on
lamps before they reach the position of use. If there is a danger of dazzling other road users by
the movement of the lamps, they may light up only when they have reached their position of use.

5.14.5.

When the concealment device has a temperature of – 30 °C to + 50 °C the headlamps must be
capable of reaching the position of use within three seconds of initial operation of the control.

Any lamp may be installed on movable components provided that the conditions specified in
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 posi-
tion, geometric visibility and photometric requirements applicable to the lamps installed on the
movable component.

When the movable components are in a position other than a ‘normal position of use’, the devices
installed on them shall not cause undue discomfort to road users.

When a lamp is installed on a movable component and the movable component is in the ‘nor-
mal position(s) of use’, the lamp must always return to the position(s) specified by the manufac-
turer in accordance with this Regulation. In the case of dipped-beam headlamps and front fog
lamps, 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 per cent 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.

(1) Also known as white or colourless retro-reflector.
(2) Nothing in this Regulation shall preclude the Contracting Parties applying this Regulation from allowing the use of white

conspicuity markings to the rear in their territories.

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 per cent
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:

5.21.1.

additional lamps satisfying all the position, geometric visibility and photometric requirements for
the above indicated lamps shall be activated when the apparent surface in the direction of the ref-
erence axis of these lamps is more than 50 per cent hidden by the movable component;

or

5.21.2.

a remark in the communication form (item 10.1. of Annex 1) shall inform other Administra-
tions that more than 50 per cent of the apparent surface in the direction of the reference axis can
be hidden by the movable components;

and

a notice in the vehicle shall inform the user that in certain position(s) of the movable compo-
nents other road users shall be warned of the presence of the vehicle on the road; for example by
means of a warning triangle or other devices according to national requirements for use on the
road.

5.21.3.

Paragraph 5.21.2. does not apply to retro-reflectors.

5.22.

5.23.

5.24.

5.25.

5.26.

With the exception of retro-reflectors, a lamp even bearing an approval mark is deemed not to
be present when it cannot be made to operate by the sole installation of a light source.

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 substitut-
ing device remains operational in its original safety function. During substitution, a tell-tale on
the dashboard (see paragraph 2.18. of this Regulation) shall indicate occurrence of a temporary
replacement and need for repair.

Where an AFS is fitted, it shall be considered equivalent to a pair of dipped-beam headlamps and,
if it provides main-beam function(s), it shall be considered equivalent to a pair of main-beam
headlamps.

Rear direction indicator lamps, rear position lamps, stop lamps (except stop lamps of category S4)
and rear fog lamps with variable luminous intensity control are allowed, which respond simul-
taneously to at least one of the following external influences: ambient lighting, fog, snowfall, rain,
spray, dust clouds, contamination of the light emitting surface, provided that their prescribed
intensity relationship is maintained throughout variation transitions. No sharp variation of inten-
sity shall be observed during transition. Stop lamps of category S4 may produce variable lumi-
nous intensity independent from the other lamps. It may be possible for the driver to set the
functions above to luminous intensities corresponding to their steady category and to return them
to their automatic variable category.

6.2.6.2.1.

In the case where a headlamp levelling device is necessary to satisfy the requirements of para-
graphs 6.2.6.1.1. and 6.2.6.1.2., the device shall be automatic.

6.2.6.2.2.

However, devices which are adjusted manually, either continuously or non-continuously, shall be
permitted, provided they have a stop position at which the lamps can be returned to the initial
inclination defined in paragraph 6.2.6.1.1. by means of the usual adjusting screws or similar
means.

These manually adjustable devices must be operable from the driver’s seat.

Continually adjustable devices must have reference marks indicating the loading conditions that
require adjustment of the dipped-beam.

The number of positions on devices which are not continuously adjustable must be such as to
ensure compliance with the range of values prescribed in paragraph 6.2.6.1.2. in all the loading
conditions defined in Annex 5.

For these devices also, the loading conditions of Annex 5 that require adjustment of the dipped-
beam shall be clearly marked near the control of the device (see Annex 8).

6.2.6.2.3.

In the event of a failure of devices described in paragraphs 6.2.6.2.1. and 6.2.6.2.2., the dipped-
beam shall not assume a position in which the dip is less than it was at the time when the failure
of the device occurred.

Measuring procedure

6.2.6.3.1.

After adjustment of the initial inclination, the vertical inclination of the dipped-beam, expressed
in percent, shall be measured in static conditions under all the loading conditions defined in
Annex 5.

6.2.6.3.2.

The measurement of the variation of dipped-beam inclination as a function of load must be car-
ried out in accordance with the test procedure set out in Annex 6.

6.2.6.4.

Horizontal orientation

The horizontal orientation of one or both dipped-beam headlamps may be varied to produce
bend lighting, provided that if the whole beam or the kink of the elbow of the cut-off is moved,
the kink of the elbow of the cut-off shall not intersect the line of the trajectory of the centre of
gravity of the vehicle at distances from the front of the vehicle which are larger than 100 times
the mounting height of the respective dipped-beam headlamps.

6.2.7.

Electrical connections

The control for changing over to the dipped-beam must switch off all main-beam headlamps
simultaneously.

The dipped beam may remain switched on at the same time as the main beams.

In the case of dipped-beam headlamps according to Regulation No 98, the gas-discharge light
sources shall remain switched on during the main-beam operation.

One additional light source or one or more LED module(s), located inside the dipped-beam head-
lamps or in a lamp (except the main-beam headlamp) grouped or reciprocally incorporated with
the respective dipped-beam headlamps, may be activated to produce bend lighting, provided that
the horizontal radius of curvature of the trajectory of the centre of gravity of the vehicle is 500 m
or less. This may be demonstrated by the manufacturer by calculation or by other means accepted
by the authority responsible for type approval.

Dipped-beam headlamps may be switched ON or OFF automatically. However, it shall be always
possible to switch these dipped-beam headlamps ON and OFF manually.

6.2.8.

Tell-tale

6.2.8.1.

Tell-tale optional.

in the case where the whole beam or the kink of the elbow of the cut-off is moved to pro-
duce bend lighting, or

(b)

if one or more LED modules are used to produce the principal dipped-beam.

It shall be activated:

(a)

in the event of a malfunction of the displacement of the kink of the elbow of the cut-off, or

(b)

in case of a failure of any one of the LED module(s) producing the principal dipped-beam.

It shall remain activated while the failure is present. It may be cancelled temporarily, but shall be
repeated whenever the device, which starts and stops the engine, is switched on and off.

In the case of a trailer, the point of the illuminating surface which is farthest from the vehicle’s
median longitudinal plane shall not be farther than 150 mm from the extreme outer edge of the
vehicle.

The distance between the inner edges of the two apparent surfaces in the direction of the refer-
ence axes shall:

For M1 and N1 category vehicles: have no special requirement;

For all other categories of vehicles: be not less than 600 mm. This distance may be reduced
to 400 mm where the overall width of the vehicle is less than 1 300 mm.

6.16.5.

Geometric visibility

Horizontal angle, 30° inwards and outwards. In the case of trailers, the angle inwards may be
reduced to 10°. If because of the construction of the trailers this angle cannot be met by the man-
datory retro-reflectors, then additional (supplementary) retro-reflectors shall be fitted, without the
width limitation (paragraph 6.16.4.1.), which shall, in conjunction with the mandatory retro-
reflectors, give the necessary visibility angle.

Vertical angle: 10° above and below the horizontal. The vertical angle below the horizontal may
be reduced to 5° in the case of a retro-reflector less than 750 mm above the ground.

6.16.6.

shape of the bodywork makes it impossible to keep within 900 mm).

6.17.4.3.

In length: At least one side retro-reflector must be fitted to the middle third of the vehicle, the
foremost side retro-reflector being not further than 3 m from the front; in the case of trailers,
account shall be taken of the length of the drawbar for the measurement of this distance.

The distance between two adjacent side retro-reflectors shall not exceed 3 m. This does not, how-
ever, apply to M1 and N1 category vehicles.

If the structure of the vehicle makes it impossible to comply with such a requirement, this dis-
tance may be increased to 4 m. The distance between the rearmost side retro-reflector and the

The initial downward inclination of the cut-off of the basic passing beam to be set in the unladen
vehicle state with one person in the driver’s seat shall be specified with a precision of 0,1 per cent
by the manufacturer and indicated in clearly legible and indelible manner on each vehicle, close
to either the front lighting system or the manufacturer’s plate, by the symbol shown in Annex 7.

Where differing initial downward inclinations are specified by the manufacturer for different light-
ing units that provide or contribute to the cut-off of the basic passing beam, these values of down-
ward inclination shall be specified with a precision of 0,1 per cent by the manufacturer and
indicated in clearly legible and indelible manner on each vehicle, close to either the relevant light-
ing units or on the manufacturers plate, in such a way that all the lighting units concerned can be
unambiguously identified.

6.22.6.1.2.

The downward inclination of the horizontal part of the ‘cut-off’ of the basic passing beam shall
remain between the limits indicated in paragraph 6.2.6.1.2. of this Regulation under all the static
loading conditions of the vehicle of Annex 5 of this Regulation; and the initial aiming shall be
within the specified values.

6.22.6.1.2.1.

in case the passing beam is generated by several beams from different lighting units, the provi-
sions according to paragraph 6.22.6.1.2. above apply to each said beam’s ‘cut-off’ (if any), which
is designed to project into the angular zone, as indicated under item 9.4. of the communication
form conforming to the model in Annex 1 to Regulation No 123.

2.

For the following tests, the mass of the passengers shall be calculated on the basis of 75 kg per person.

Loading conditions for different types of vehicles:

2.1.

Vehicles in category M1 (1):

2.1.1.

The angle of the light beam of the dipped-beam headlamps shall be determined under the following load conditions:

2.1.1.1. one person in the driver’s seat;

2.1.1.2.

the driver, plus one passenger in the front seat farthest from the driver;

2.1.1.3.

the driver, one passenger in the front seat farthest from the driver, all the seats farthest to the rear occupied;

2.1.1.4. all the seats occupied;

2.1.1.5. all the seats occupied, plus an evenly distributed load in the luggage boot, in order to obtain the permissible load
on the rear axle or on the front axle if the boot is at the front. If the vehicle has a front and a rear boot, the addi-
tional load must be appropriately distributed in order to obtain the permissible axle loads. However, if the maxi-
mum permissible laden mass is obtained before the permissible load on one of the axles, the loading of the boot(s)
shall be limited to the figure which enables that mass to be reached;

2.1.1.6. driver, plus an evenly distributed load in the boot, in order to obtain the permissible load on the corresponding

axle.

However, if the maximum permissible laden mass is obtained before the permissible load on the axle, the loading
of the boot(s) shall be limited to the figure which enables that mass to be reached.

2.1.2.

In determining the above loading conditions, account must be taken of any loading restrictions laid down by the
manufacturer.

2.2.

Vehicles in categories M2 and M3 (1);

The angle of the light beam from the dipped-beam headlamps must be determined under the following loading
conditions:

2.2.1.

vehicle unladen and one person in the driver’s seat;

2.2.2.

vehicles laden such that each axle carries its maximum technically permissible load or until the maximum permis-
sible mass of the vehicle is attained by loading the front and rear axles proportionally to their maximum techni-
cally permissible loads, whichever occurs first.

2.3.

Vehicles in category N with load surfaces:

2.3.1.

The angle of the light beam from the dipped-beam headlamps must be determined under the following loading
conditions;

2.3.1.1. vehicle unladen and one person in the driver’s seat;

2.3.1.2. driver, plus a load so distributed as to give the maximum technically permissible load on the rear axle or axles, or
the maximum permissible mass of the vehicle, whichever occurs first, without exceeding a front axle load calcu-
lated as the sum of the front axle load of the unladen vehicle plus 25 per cent of the maximum permissible pay-
load on the front axle. Conversely, the front axle is so considered when the load platform is at the front.

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 inclination specified by the motor vehicle manufacturer serving as a reference
value for the calculation of permissible variations.

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 varia-
tions 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 per cent is equal to 10 mrad).

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

(h1 – h2)
L

× 100

where:

h1

h2

L

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 dis-
tance L.

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

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.

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 inclina-

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

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 reproducibil-
ity of measurements of dipped-beam inclination can be assured with an accuracy of ± 0,5 mrad (± 0,05 per cent
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 per cent 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 per cent 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. above.

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).

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. below. The load shall be applied
gradually without subjecting the vehicle to excessive shocks.

5.1.1. Where an AFS is fitted, the measurements shall be carried out with the AFS in its neutral state.

5.2.

Determination of the measured initial inclination

The vehicle shall be prepared as specified in paragraph 4. above and laden as specified in Annex 5 (first loading
condition of the respective vehicle category). Before each measurement, the vehicle shall be rocked as specified in
paragraph 5.4. below. Measurements shall be made three times.

5.2.1.

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

5.2.2.

If any measurement differs from the arithmetic mean of the results by more than 2 mrad (0,2 per cent 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 per cent 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 plat-
form 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. above.

If the vehicle is fitted with a manual headlamp-levelling system, the latter shall be adjusted to the positions speci-
fied 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 dif-
ference between the stated initial inclination and the lower and upper limits specified for approval) with a safety
margin of 4 mrad (0,4 per cent 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.

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 per cent 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 per cent 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, if, under all loading conditions, the variation between the measured initial inclina-
tion 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).

5.5.5.

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.

Specifications

1.1.

Downward inclination of the dipped-beam must in all cases be produced in one of the following ways:

(a)

by moving a control downwards or to the left;

(b) by rotating a control in a counterclockwise direction;

(c)

by depressing a button (push-pull control).

If several buttons are used to adjust the beam, the button which gives the greatest downward inclination must be
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 incli-

nation 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 nec-
essarily 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:

Symbols employing five lines instead of four may also be used
