Fog Lights

[Mark1]

We all know that fog light should only be used in fog and when can you see knowmore than a 100m, if you didn't you do now Now over the last couple of years manufactors have been setting cars up so that when you turn the fog light on one side comes on, the question is, Is this legal?

[DanSE4]

Only one rear fog lamp is required, same as reverse lights & there's quite a few cars out there that only have one of each. Usually one occupies the same space as the other in opposite sides of the rear clusters.

From the MOT Testers manual.

This 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.
