stationary vehicle in a built-up area. In such circumstances it replaces the front and rear
position lamps;
2.7.23. "End-outline marker lamp" means the lamp fitted near to the extreme outer edge and as
close as possible to the top of the vehicle and intended to indicate clearly the vehicle's
overall width. This lamp is intended, for certain vehicles and trailers, to complement the
vehicle's front and rear position lamps by drawing particular attention to its bulk;
2.7.24. "Side-marker lamp" means a lamp used to indicate the presence of the vehicle when

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 the case of AFS being 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 is 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.
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;

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.);
5.5.2. 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;
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 or Single 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. The photometric and colorimetric requirements of a lamp shall be fulfilled when all other
functions with which this lamp is grouped, combined or reciprocally incorporated are
switched OFF.
However, when a front or rear position lamp is reciprocally incorporated with one or more
other function(s) which can be activated together with them, the requirements regarding
colour of each of these other functions shall be fulfilled when the reciprocally incorporated
function(s) and the front or rear position lamps are switched ON.
5.7.1.2. Stop lamps and direction indicator lamps are not permitted to be reciprocally incorporated.
5.7.1.3. Where stop lamps and direction indicator lamps are grouped the following conditions shall
be met:
5.7.1.3.1. 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.
5.7.1.3.2. Their apparent surfaces in the direction of the reference axis, based upon the areas
bounded by the outline of their light emitting surfaces, do not overlap.

5.8.1. For the purposes of reducing the geometric visibility angles, the position of a lamp with
regard to height above the ground, shall be measured from the H plane.
5.8.2. 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.
5.8.3. 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

MEASUREMENT OF THE VARIATION OF DIPPED-BEAM INCLINATION AS A FUNCTION OF LOAD
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 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 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 10mrad).
If the inclination is expressed in percentage inclination, it can be calculated by means of the
following formula:
where:
( h − h )
L
× 100
h
h
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 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 h ):
is the distance, in millimetres, from the screen to the centre of reference.

4.2. 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 shall 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 8h 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).
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. 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 2mrad (0.2% 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 2mrad
(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 ±0.2mrad (±0.02% 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 2mrad (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 2mrad
(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, if, under all loading conditions, the variation between the
measured initial 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).
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.

THE CONTROLS FOR THE HEADLAMP-LEVELLING DEVICES REFERRED
TO IN PARAGRAPH 6.2.6.2.2. OF THIS REGULATION
1. SPECIFICATIONS
1.1. Downward inclination of the dipped-beam shall in all cases be produced in one of the
following ways:
(a)
(b)
(c)
By moving a control downwards or to the left;
By rotating a control in a counter clockwise direction;
By depressing a button (push-pull control).
If several buttons are used to adjust the beam, the button which gives the greatest
downward inclination shall 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 shall 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 shall be explained in the owner's handbook.
1.5. Only the following symbols may be used to identify the controls:
