Council Directive 93/92/EEC (repealed)Dangos y teitl llawn

B. GENERAL SPECIFICATIONS U.K.

1. The lighting and light-signalling devices must be so installed that under normal conditions of use and notwithstanding any vibration to which they may be subjected, they retain the characteristics laid down and enable the vehicle to comply with the requirements of this Directive. In particular, it must not be possible for the adjustment of the lamps to be inadvertently disturbed. U.K.

2. The illuminating lamps must be so fitted that their alignment can easily be set correctly. U.K.

3. For all light-signalling devices the reference axis of the lamp when fitted to the vehicle must be perpendicular to the median longitudinal plane of the vehicle in the case of side retro reflectors and parallel to that plane in the case of all other signalling devices. In each direction a tolerance of 3° is allowed. U.K.

In addition, any specific instructions as regards fitting laid down by the manufacturer must be complied with.

4. The height and alignment of lamps are checked, in the absence of specific instructions, with the vehicle unladen and located on a flat horizontal surface, with its median longitudinal plane being vertical and its handlebars or steering wheel in the dead-ahead position. The tyre pressure must be that specified by the manufacturer for the specific loading conditions laid down. U.K.

5. In the absence of specific requirements, lamps constituting a pair must: U.K.

5.1. be installed on the vehicle symmetrically in relation to the median longitudinal plane; U.K.

5.2. be symmetrical to each other in relation to the median longitudinal plane; U.K.

5.3. fulfil the same colorimetric requirements; U.K.

5.4. have substantially identical photometric characteristics. U.K.

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

7. The maximum height above ground is measured from the highest point, and the minimum height from the lowest point, of the illuminating surface. The minimum height above ground of dipped-beam headlamps must be measured from the lower edge of the lens, or of the reflector if the latter is higher. U.K.

8. In the absence of specific requirements no lamps other than direction indicator lamps and the hazard warning signal may emit a flashing light. U.K.

9. No red lamp must be visible towards the front and no white lamp other than any reversing lamp fitted visible towards the rear. This condition is checked as follows (see drawings according to the types of two or three-wheel vehicles set out in Appendice 1 to Annexes II to VI): U.K.

9.1. for the visibility of a red lamp towards the front: there must be no direct visibility of a red lamp if viewed by an observer moving within Zone 1 in a transverse plane situated 25 m in front of the foremost part of the vehicle; U.K.

9.2. for the visibility of a white lamp towards the rear: there must be no direct visibility of a white lamp if viewed by an observer moving within Zone 2 in a transverse plane situated 25 m behind the rearmost part of the vehicle; U.K.

9.3. Zones 1 and 2, as seen by the observer, are limited in their respective planes as follows: U.K.

9.3.1. as regards height, two horizontal planes which are 1 m and 2.2 m respectively above the ground; U.K.

9.3.2. as regards width, by two vertical planes making an angle of 15° towards the front and rear respectively, and outside the vehicle by reference to the median longitudinal 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 and representing its overall width, and of the transverse planes representing the overall length of the vehicle. U.K.

10. The electrical connections must be such that the front position lamp or the dipped-beam headlamp, if there is no front position lamp, the rear position lamp and the rear registration plate lamp can only be switched on and off simultaneously. U.K.

11. In the absence of specific requirements, the electrical connections must be such that the main-beam headlamp, the dipped-beam headlamp and the fog lamp cannot be switched on until the lamps referred to in section 10 have also been switched on. This requirement does not apply, however, to main-beam or dipped-beam headlamps when their optical 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. U.K.

12. Telltales U.K.

12.1. All telltales must be clearly visible to the driver in the normal driving position. U.K.

12.2. Where provision has been made for a circuit-closed telltale it may be replaced by an operational telltale. U.K.

13. Colours emitted by the lamps: U.K.

The colours emitted by the lamps are as follows:

Main-beam headlamps:	white
Non-triangular front retro-reflector:	white
Dipped-beam headlamp:	white
Direction-indicator lamp:	amber
Stop lamp:	red
Front position lamp:	white
Rear position lamp:	red
Front fog lamp:	white/yellow
Rear fog lamp:	red
Reversing lamp:	white
Hazard warning signal:	amber
Rear registration plate lamp:	white
Non-triangular side retro-reflector:	amber
Non-triangular rear retro-reflector:	red
Pedal retro-reflector:	amber

The definition of lamp colours must be as laid down in Appendix 2.

14. All lighting and light-signalling devices must be component type-approved. However, pending the entry into force of harmonized provisions concerning lighting and light-signalling devices on mopeds with engines of no more than 0,5 kW and a maximum speed not exceeding 25 km/h, such mopeds may be fitted with dipped-beam headlamps and/or rear position lamps which have not been approved. In such cases, the manufacturer must declare that the devices concerned conform to ISO standard 6742/1. Specific additional requirements will be laid down in accordance with the procedure outlined in Article 13 of Directive 70/156/EEC. U.K.
