1.3 Rear Fog Lamps
InformationThis inspection applies to the one rear fog lamp which is required to be fitted to the centre or offside of vehicles first used on or after 1 April 1980.
Note: A rear fog lamp is permitted to operate independently of headlamp, position lamp or ignition systems.
A rear fog lamp is not required to be fitted to vehicles used only during the hours of daylight, which are fitted with neither front nor rear position lamps, etc. See 1.1.A.
Tricycles and quadricycles are not required to be fitted with rear fog lamps.
Method of Inspection1. With dipped head lamps and the ignition switched on, check:
a. the presence, security and operation of the switch
b. the presence and operation of the tell-tale. Note: Some tell-tales may be in the form of a coloured tag on a switch.
2. With the rear fog lamps switched on check that a rear fog lamp:
a. is securely fitted to the centre or offside of the vehicle
b. is working
c. is not obscured
d. is in good condition
Note: An effective proprietary repair e.g. lens repair tape etc. must be assessed on its merits, considering security, colour, light output and durability.
e. shows light of the correct colour
f. is not adversely affected by the operation of any other lamp.
Reason for Rejection1. A mandatory rear fog lamp switch:
a. missing, insecure, faulty, or not able to be operated from the normal driving position

2. A mandatory rear fog lamp:
a. missing, insecure, obviously incorrectly positioned or does not face to the rear b. inoperative or less than 50% of the light sources illuminating
c. obscured so that less than 50% of the lamp illuminating surface is visible from the rear

e. shows other than a steady red light to the rear
