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

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;

Notes:
Figure 1
Dipped-beam Downward Inclination of a Category M Vehicle
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 10m
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 ±0.5mrad (±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 ±0.5mrad
(±0.05% inclination).
3.4. During measurements, the ambient temperature shall be between 10°C and 30°C.
4. VEHICLE PREPARATION
4.1. Measurements shall be carried out on a vehicle which has travelled a distance of between
1,000km and 10,000km, preferably 5,000km.

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 shall 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
4mrad (0.4% inclination).

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 1.2% to 3.8% for headlamp mounting height h >1.2m
In the case of a Class "F3" front fog lamp with (a) light source(s) having a total objective
luminous flux which exceeds 2,000lm, the variation of the downward inclination as a function
of the loading conditions specified within this section shall remain within the range:
0.7% to 3.3% for front fog lamp mounting height h ≤0.8;
1.2% to 3.8% for front fog lamp mounting height h >0.8m
