5. GENERAL SPECIFICATIONS

5.1. The lighting and light-signalling devices shall be so fitted that in normal conditions of use, and notwithstanding the vibrations to which they may be subjected, they retain the characteristics prescribed by this Regulation and enable the vehicle to comply with the requirements of this Regulation. In particular, it shall not be possible for the lamps to be inadvertently maladjusted.

5.2. The illuminating lamps shall be so installed that correct adjustment of their orientation can easily be carried out.

5.3. For all light-signalling devices the reference axis of the lamp when fitted to the vehicle shall be parallel to the bearing plane of the vehicle on the road; in addition, it shall be perpendicular to the median longitudinal plane of the vehicle in the case of side reflex reflectors and parallel to that plane in the case of all other light-signalling devices. A tolerance of ±3° shall be allowed in each direction. In addition, if specifications for fitting are provided by the manufacturer they shall be complied with.

5.4. 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, its median longitudinal plane being vertical and the handlebars being in the position corresponding to the straight ahead movement. The tyre pressures shall be those prescribed by the manufacturer for the particular conditions of loading required in this Regulation.

5.5. In the absence of specific instructions lamps constituting a pair and having the same function shall:

5.5.1. be mounted symmetrically in relation to the median longitudinal plane;

5.5.2. be symmetrical to one another in relation to the median longitudinal plane;

5.5.3. satisfy the same colorimetric requirements; and

5.5.4. have identical nominal photometric characteristics.

5.6. In the absence of specific instructions, lamps having different functions may be independent or be grouped, combined or incorporated in one device, on condition that each such lamp satisfies the requirements applicable to it.

5.7. The maximum height above ground shall be measured from the highest point and the minimum height from the lowest point of the illuminating surface. For passing lamps, the minimum height from the ground shall be measured from the bottom of the lens or the reflector, whichever of these is the higher.

5.8. In the absence of specific instructions, no lamps other than direction-indicator lamps
