Lighting Regulations Requirements
The lighting regulations are complex, and many of the detailed requirements are only relevant to vehicle manufacturers and body builders. But basically, between sunset and sunrise all vehicles in motion on a road, except a motorcycle or pedal cycle being pushed, must keep lit and unobscured every front lamp, rear position lamp, rear registration plate lamp, side marker lamp and end outline marker lamp required to be fitted.
During the hours of darkness (half an hour after sunset to half an hour before sunrise) a vehicle fitted with obligatory dipped-beam headlamps and used on the road, except on a restricted road where the street lamps are not more than 200 yards apart or when the vehicle is parked, must keep every such lamp lit. Vehicle markings and reflectors also come under the lighting regulations.
