2.7.16. "Retro-reflector" means a device used to indicate the presence of a vehicle by the
reflection of light emanating from a light source not connected to the vehicle, the observer
being situated near the source;
For the purposes of this Regulation the following are not considered as retro-reflectors:
2.7.16.1. retro-reflecting number plates;
2.7.16.2. the retro-reflecting signals mentioned in the ADR (European Agreement concerning the

Paragraph 6.22.7.4 of this Regulation;
2.7.28.6. "Neutral state" means the state of the AFS when a defined mode of the Class C passing
beam ("basic passing beam") or of the main beam, if any, is produced, and no AFS control
signal applies.
2.8. "Light-emitting surface" of a "lighting device", "light-signalling device" or a
retro-reflector means all or part of the exterior surface of the transparent material as
declared in the request for approval by the manufacturer of the device on the drawing, see
Annex 3;
2.9. "Illuminating surface" (see Annex 3);
2.9.1. "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 illuminating surface to be considered (for example, in the figure of Paragraph 6.22.4
below, the individual 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).

2.13. "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 β
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 devices for indirect vision;
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.
2.14.6. of service-door lighting systems on vehicles of Categories M and M as specified in
Paragraph 2.7.
2.15. "Overall width" means the distance between the two vertical planes defined in
Paragraph 2.14. above;

2.21. "Ground" means the surface on which the vehicle stands which should be substantially
horizontal;
2.22. "Movable components" of the vehicle mean those body panels or other vehicle parts the
position(s) of which can be changed by tilting, rotating or sliding without the use of
tools. They do not include tiltable driver cabs of trucks;
2.23. "Normal position of use of a movable component" means the position(s) of a movable
component specified by the vehicle manufacturer for the normal condition of use and the
park condition of the vehicle;
2.24. "Normal condition of use of a vehicle" means:
2.24.1. for a motor vehicle, when the vehicle is ready to move with its propulsion engine running
and its movable components in the normal position(s) as defined is Paragraph 2.23.;
2.24.2. and for a trailer, when the trailer is connected to a drawing motor vehicle in the conditions as
prescribed in Paragraph 2.24.1. and its movable components are in the normal position(s)
as defined in Paragraph 2.23.
2.25. "Park condition of a vehicle" means:
2.25.1. for a motor vehicle, when the vehicle is at a standstill and its propulsion engine is not
running and its movable components are in the normal position(s) as defined in
Paragraph 2.23;
2.25.2. and for a trailer, when the trailer is connected to a drawing motor vehicle in the condition as
described in Paragraph 2.25.1. and its movable components are in the normal position(s) as
defined in Paragraph 2.23.
2.26. "Bend lighting" means a lighting function to provide enhanced illumination in bends.
2.27. "Emergency stop signal" means a signal to indicate to other road users to the rear of the
vehicle that a high retardation force has been applied to the vehicle relative to the prevailing
road conditions.
2.27. "Pair" means the set of lamps of the same function on the left- and right-hand side of the
vehicle;
2.27.1. "Matched pair" means the set of lamps of the same function on the left- and right-hand
side of the vehicle, which, as a pair, complies with the photometric requirements.

3.3. An unladen vehicle fitted with a complete set of lighting and light-signalling equipment, as
prescribed in Paragraph 3.2.2. above, and representative of the vehicle type to be approved
shall be submitted to the technical service responsible for conducting approval tests.
3.4. The document provided in Annex 1 of this Regulation shall be attached to the type-approval
documentation.
4. APPROVAL
4.1. If the vehicle type submitted for approval pursuant to this Regulation meets the
requirements of the Regulation in respect of all the devices specified in the list, approval of
that vehicle type shall be granted.
4.2. An approval number shall be assigned to each type approved. Its first two digits (at present
03, corresponding to the 03 series of amendments) shall indicate the series of amendments
incorporating the most recent major technical amendments made to the Regulation at the
time of issue of the approval. The same Contracting Party shall not assign this number to
another vehicle type or to the same vehicle type submitted with equipment not specified in
the list referred to in Paragraph 3.2.2. above, subject to the provisions of Paragraph 7 of this
Regulation.
4.3. Notice of approval or of extension or refusal of approval or production definitely discontinued
of a vehicle type/part pursuant to this Regulation shall be communicated to the Parties to
the 1958 Agreement applying this Regulation, by means of a form conforming to the model
in Annex 1 to this Regulation.
4.4. There shall be affixed, conspicuously and in a readily accessible place specified on the
approval form, to every vehicle conforming to a vehicle type approved under this Regulation,
an international approval mark consisting of:
4.4.1. A circle surrounding the Letter "E" followed by the distinguishing number of the country
which has granted approval

5.5.3. satisfy the same colorimetric requirements and have substantially identical photometric
characteristics. 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. Lamps may be grouped, combined or reciprocally incorporated with one another provided
that all requirements regarding colour, position, orientation, geometric visibility, electrical
connections and other requirements, if any, are fulfilled.
5.7.1.1. However, where stop lamps and direction indicator lamps are grouped, any horizontal or
vertical 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 separating adjacent areas of different colour.
5.7.2. Where the apparent surface of a single lamp is composed of two or more distinct parts, it
shall satisfy the following requirements:
5.7.2.1. 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 perpendicularly 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.
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.

5.12. 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 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.
5.13. Tell-tale
Where a circuit-closed tell-tale is prescribed by this Regulation it may be replaced by an
"operating" tell-tale.
5.14. Concealable Lamps
5.14.1. 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.
5.14.2. 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.
5.14.3. 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, the control referred to above is required only to activate the
dipped-beam headlamps.
5.14.4. 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.

5.17. Any lamp may be installed on movable components provided that the conditions specified in
Paragraphs 5.18., 5.19. and 5.20. are fulfilled.
5.18. Rear position lamps, rear direction-indicators and rear retro-reflectors, triangular as well as
non triangular, may be installed on movable components only:
5.18.1. 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
5.18.2. 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.
5.19. 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.
5.20. 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 fog lamps, this requirement shall be considered satisfied if, when the movable
components are moved and returned to the normal position ten 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 ten 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.
5.21. 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:
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 reference axis of these lamps is more than 50% hidden by the movable component
or

6. INDIVIDUAL SPECIFICATIONS (Regulation Nos. 98 and 112)
6.1. Main-beam Headlamp
6.1.1. Presence
6.1.2. Number
Mandatory on motor vehicles. Prohibited on trailers.
Two or four.
For vehicles of the Category N :
Two extra main-beam headlamps may be installed.
Where a vehicle is fitted with four concealable headlamps the installation of two additional
headlamps shall only be authorised for the purpose of light-signalling, consisting of
intermittent illumination, at short intervals (see Paragraph 5.12.) in daylight.
6.1.3. Arrangement
6.1.4. Position
No individual specifications.
6.1.4.1. In width: no individual specifications.
6.1.4.2. In height: no individual specifications.
6.1.4.3. In length: at the front of the vehicle and fitted in such a way that the light emitted does not
cause discomfort to the driver either directly or indirectly through the rear-view mirrors
and/or other reflecting surfaces of the vehicle.
6.1.5. Geometric visibility
6.1.6. Orientation
The visibility of the illuminating surface, including its visibility in areas which do not appear to
be illuminated in the direction of observation considered, must be ensured within a divergent
space defined by generating lines based on the perimeter of the illuminating surface and
forming an angle of not less than 5° with the axis of reference of the headlamp. The origin
of the angles of geometric visibility is the perimeter of the projection of the illuminating
surface on a transverse plane tangent to the foremost part of the lens of the headlamp.
Towards the front.
Not more than one main-beam headlamp on each side of the vehicle may swivel to produce
bend lighting.

6.2.4. Position
6.2.4.1. In width: that edge of the apparent surface in the direction of the reference axis which is
farthest from the vehicle's median longitudinal plane shall be not more than 400 mm from
the extreme outer edge of the vehicle.
The inner edges of the apparent surfaces in the direction of the reference axes shall be not
less than 600 mm apart. This does not apply, however, for M and N Category vehicles; for
all other categories of motor vehicles this distance may be reduced to 400 mm where the
overall width of the vehicle is less than 1 300 mm.
6.2.4.2. In height: not less than 500 mm and not more than 1 200 mm above the ground. For
Category N G (off-road) vehicles , the maximum height may be increased to 1 500 mm.
6.2.4.3. In length: at the front of the vehicle. This requirement shall be deemed to be satisfied if the
light emitted does not cause discomfort to the driver either directly, or indirectly through the
rear-view mirrors and/or other reflecting surfaces of the vehicle.
6.2.5. Geometric Visibility
6.2.6. Orientation
Defined by angles α and β as specified in Paragraph 2.13.
α = 15° upwards and 10° downwards,
β = 45° outwards and 10° inwards.
Since the photometric values required for dipped-beam headlamps do not cover the full
geometric field of vision, a minimum value of 1 cd in the space remaining is required for
type-approval purposes. The presence of partitions or other items of equipment near the
headlamp shall not give rise to secondary effects causing discomfort to other road users.
Towards the front.
6.2.6.1. Vertical orientation

the maximum permissible mass of the vehicle is attained by loading the front and rear axles
proportionally to their maximum technically 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

Figure 1
Dipped-beam Downward Inclination of a Category M Vehicle
Notes:
1. This drawing represents a Category M 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. 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.
3.2. The ground on which measurements are made shall be as flat and horizontal as possible,
so that the reproducibility of measurements of dipped-beam inclination can be assured with
an accuracy of ± 0.5 mrad (± 0.05% inclination).
3.3. 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. 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.

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. M 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 then 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. M , M and N Category Vehicles with Conventional Suspension
5.4.2.1. If the treatment method for Category M 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. above.
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).
