1.1 Front and Rear Position Lamps and Registration Plate Lamps

Information
Method of Inspection
Reason for rejection
This inspection applies to all vehicles, except those which either have no front or rear position lamps or have such lamps permanently disconnected, painted over or masked that are:

. only used during daylight hours, and

. not used at times of seriously reduced visibility.

If this situation occurs, the vehicle presenter should be issued with a VT32 (advisory notice) recording the above.

Obligatory front and rear position lamps are lamps required by Regulations to be fitted to a vehicle to indicate its presence and width when viewed from the front or rear.

Two front position lamps must be fitted, one on each side and show a steady white light to the front (or yellow if incorporated in a yellow headlamp)
.
Two rear position lamps must also be fitted, one on each side, showing a steady red light to the rear.

Note: A bus first used before 1 April 1955 requires only one rear position lamp on the centre-line or offside of the vehicle.

Dim-dip headlamp systems require the front position lamps to be checked for operation with the ignition switched off. This may involve the operation of a separate switch.

Additional or optional lamps are not included in the inspection.

Tricycle and quadricycle requirements are detailed at Section 9.1..
