b) two rearward-facing lamps.
2. A light trailer with an overall width of less than 1.8m is fitted with end-outline marker lamps.
3. An end-outline marker lamp is not positioned so that it gives an indication of the vehicle’s dimensions, ie lamps are fitted other than around the outline of the vehicle.
Condition
4. A lamp is insecure.
5. A lens is missing, or has a hole, crack or other damage that allows moisture or dirt to enter.
6. A reflector is damaged or has deteriorated so that light output is reduced.
Performance

8. When switched on, an end-outline marker lamp emits a light that is:
a) not substantially white or amber to the front, or
b) not substantially red to the rear, or
c) not diffuse, or
d) not projected to the front or rear, or
e) not approximately of the same colour and intensity as the other lamp if fitted in a pair, or
f) not steady, or
g) not bright enough to indicate the presence and dimensions of the vehicle to other road users.
9. Where a lamp comprises an array of light sources (eg LEDs), fewer than 75% of these operate.
Note 1
End-outline marker lamp means a position lamp designed to be fitted near the outer extremity of the vehicle in addition to forward-facing and rearward-facing position lamps, and includes a cab roof lamp.
Position lamp means a low-intensity lamp that is designed to indicate the presence and dimensions of a vehicle to other road users, being:
a) a forward-facing position lamp (front side or park lamp), or
b) a rearward-facing position lamp (rear side lamp or tail lamp), or
c) a side-marker lamp, or
d) an end-outline marker lamp (including cab roof lamps).
Note 2
A forward-facing permitted lamp that does not comply with the equipment, condition and performance requirements must be made to comply or be removed from the vehicle. A rearward-facing end-outline marker lamp that does not comply with the equipment, condition and performance requirements must be made to comply or be disabled so that it does not emit a light.
