ANNEX IX

Requirements applying to installation of lighting and light signalling devices, including automatic switching of lighting

1. Requirements for the approval of a type of vehicle with regard to installation of lighting

1.1. Vehicles of category L1e shall meet all the relevant requirements of UNECE regulation No 74 (1). The requirements of points 1.8 to 1.12 shall also be taken into account.

1.1.1. Vehicles of category L1e-B shall, in the absence of uniform requirements in UNECE regulation No 74, always be fitted with a rear registration plate lamp.

1.1.2. Vehicles of category L1e may, in the absence of specific requirements in UNECE regulation No 74, be fitted with daytime running lamps which are activated instead of automatically switched-on headlamps and which comply with the requirements set out in points 2.3.4 to 2.3.4.7 below.

1.1.3. Vehicles of category L1e-A may alternatively to the requirements laid down in points 1.1 to 1.1.2 be fitted with all the following devices: a headlamp emitting white light towards the front when the vehicle is in motion, a rear position lamp emitting red light towards the rear when the vehicle is in motion, amber side retro-reflectors (one on each side), amber pedal retro-reflectors (towards the front and the rear, both on each side) and a red rear retro-reflector. These lighting devices need not be component type-approved and no other specific fitting, switching and electrical connection requirements apply. In such cases, the manufacturer shall declare that the lighting devices concerned conform to ISO standard 6742-1:1987 and 6742-2:1985.

1.2. Vehicles of category L2e shall meet the requirements of points 1.10 to 2.5.

1.3. Vehicles of category L3e shall meet all the relevant requirements of UNECE regulation No 53. The requirements of points 1.8 to 1.12 shall also be taken into account.

1.4. Vehicles of category L4e shall meet the requirements of points 1.10 to 1.12 and 3 to 3.2.8.1.

1.5. Vehicles of category L5e shall meet the requirements of points 1.10 to 2.5.

1.6. Vehicles of category L6e shall meet the requirements of points 1.10 to 2.5.

1.7. Vehicles of category L7e shall meet the requirements of points 1.10 to 2.5.

1.8. Vehicles of category L1e-A may be fitted with retro-reflective bands on the tyre sidewalls or rims so as to provide a visual impression of circles of white light and making such vehicles easily recognisable.

1.9. Vehicles of categories L1e and L3e may be fitted with additional rear and side retro-reflective devices and materials provided that they do not impair the effectiveness of the mandatory lighting and light-signalling devices. In particular, luggage compartments and saddle bags may be fitted with retro-reflective materials, provided that these have the same colour as the lighting devices at that location.

1.10. No vehicle shall be fitted with auxiliary light sources of which the emitted light can be observed either directly or indirectly under normal driving conditions, other than those for the purpose of illuminating controls, tell-tales and indicators or the occupant compartment.

1.11. No vehicle shall be fitted with lighting devices which, due to a lack of specific wording in the respective component type-approval provisions and unless explicitly allowed by those provisions, display or give the appearance of movement or expansion of its light on the apparent surface or any strobe or flashing effect. Furthermore, if the apparent surface of a lighting function is reduced in size due to the activation of another lighting function with a different colour, the remaining apparent surface of the first named function shall continue to meet the relevant colorimetric and appropriate luminous intensity requirements (e.g. left and right-hand side tail lamp consisting of two rear position lamp rings with LEDs of which the outer ring can become the direction indicator lamp and the inner ring remains a combined rear position and stop lamp). All operation modes shall be duly covered by the lighting device component type-approval.

1.12. Where automatically switched-on headlamp or daytime running lamp activation is linked to the running of an engine, this shall be construed as being linked to the activation of the master control switch. This shall in particular be the case for vehicles with electric or other alternative propulsion systems and vehicles equipped with an automatic engine stop/start system.

2. Requirements concerning vehicles of categories L2e, L5e, L6e and L7e.

2.1. General specifications

2.1.1. All lighting devices shall be type-approved and fitted in accordance with the component manufacturer’s specifications and installed so that, under normal conditions of use and notwithstanding any vibration to which they may be subjected, they retain the characteristics as prescribed and enable the vehicle to comply with the requirements of this Annex. In particular, it shall not be possible for the lighting devices to be inadvertently maladjusted.

2.1.2. The illuminating lamps shall be fitted so that their alignment can easily be set correctly.

2.1.3. The reference axis of the lighting device when fitted to the vehicle shall be perpendicular to the longitudinal median plane of the vehicle in the case of side retro-reflectors and parallel to that plane in the case of all other lighting devices, with a permitted tolerance of 3°.

2.1.4. The height and alignment of lighting devices are verified with the vehicle with its mass in running order, plus the mass of any propulsion batteries, placed on a flat horizontal surface, with the steered wheel(s) in the straight ahead position and the tyre pressures adjusted to the manufacturer’s specified values.

2.1.5. In the absence of specific requirements, lighting devices constituting a pair shall:

— be installed on the vehicle symmetrically in relation to the longitudinal median plane,

— be symmetrical to each other in relation to the longitudinal median plane (which includes being in stacked formation),

— have identical colorimetric requirements, and

2.1.6. In the absence of specific instructions, lamps having different functions may be independent or grouped, combined or reciprocally incorporated in one device, provided that each lamp complies with the requirement applicable to it.

2.1.7. The maximum height above ground is measured from the highest point, and the minimum height from the lowest point, of the light-emitting surface.

2.1.8. In the absence of specific requirements, no lamps other than direction indicator lamps, the hazard warning signal and the emergency braking signal may emit a flashing light.

2.1.9. No light-emitting surface of any red lamp, with the exception of rearmost side marker lamps, shall be visible towards the front and no light-emitting surface of any white lamp, with the exception of reversing lamps, shall be visible towards the rear. No interior or instrument cluster lighting shall be taken into account and the condition is checked as follows:

2.1.9.1. No red lamp shall be directly visible to an observer moving within Zone 1 in a transverse plane situated 25 m in front of the foremost part of the vehicle (see Figure 9-1).

2.1.9.2. No white lamp shall be directly visible to an observer moving within Zone 2 in a transverse plane situated 25 m behind the rearmost part of the vehicle (see Figure 9-2).

2.1.9.3. Zones 1 and 2 are limited in their respective planes as follows (see Figures 9-1 and 9-2): 2.1.9.3.1. Two horizontal planes which are 1,0 m and 2,2 m respectively above the ground; 2.1.9.3.2. Two vertical planes under an angle of 15° towards the front and rear of the vehicle respectively, and outward of the vehicle by reference to the longitudinal median plane of the vehicle. These planes contain, respectively, the vertical lines of intersection of the vertical planes parallel to the longitudinal median plane of the vehicle representing its overall width, and of the transverse vertical planes representing the overall length of the vehicle.
