1. A cosmetic lamp (ie one not listed in Table 4-15-1) that is fitted to a vehicle:
a) has a part of its light-emitting surface positioned within 250mm of any mandatory lamp, or
b) is not mounted in a fixed position, or
c) is positioned so that its light-emitting surface is visible within the shaded areas in Figure 4-15-1.
2. A work lamp that is fitted to a vehicle is wired in such a way that the switch or circuit for any mandatory or optional lamp controls it.
3. When switched on, a cosmetic lamp with a light-emitting surface not visible within the shaded areas in Figure 4-15-1 emits a light that:
a) is not diffuse, or
b) flashes or otherwise varies in intensity or colour, or
c) revolves, rotates or otherwise moves, or
d) is too bright and likely to dazzle other road users, or
e) is likely to cause confusion about the orientation of the vehicle, or
f) is red when seen directly from the front, or
g) is not red or amber when seen directly from the rear.
4. A forward-facing reflector on a vehicle reflects white light shining on it as anything other than white or amber light.
5. A side-facing reflector on a vehicle reflects white light shining on it as anything other than white or amber light.
A rear or side cosmetic lamp that does not comply with requirements for condition or performance must be made to comply, or be disabled so that it does not emit a light.
Note 2 Definitions
Lamp means a device designed to emit light, and includes an array of separate light sources that appear as a continuous illuminated surface.
Work lamp means a high-intensity lamp that is not necessary for the operation of the vehicle but is designed to illuminate the area or scene and include scene lamps, spot lamps and alley lamps.
Scene lamp means a work lamp designed to provide a fixed or movable beam of light to illuminate the area around the vehicle or the vehicle itself.
Alley lamp means a work lamp designed primarily to provide a fixed or movable beam of light to the side of the vehicle it is fitted to.
Reflective material (or retroreflective material) means any material that is designed to reflect incident light back towards a light source or in a specific direction; but does not include a reflector.
Cosmetic lamp means any lamp that is not listed in Table 4-15-1.
A forward-facing cosmetic lamp that does not comply with the equipment, condition and performance requirements must be made to comply or be removed from the vehicle.
