Lighting Regulations
Abbreviated to RVLR: the
Road Vehicle Lighting Regulations 1989 (amended in
1994,
1996,
2001,
2005, again in
2005 and
2009) require pedal cycles to have various lights and reflectors fitted, clean and working properly, when being ridden on a public road between sunset and sunrise. Cyclists may also be required to light up in conditions of seriously reduced visibility during the day, but only if they have functional lights already fitted. Lights are not required when the cycle is stationary or being pushed along the roadside.
It has to be said that the fine details of RVLR are seldom enforced; and provided you show some kind of white light in front and red behind you are unlikely to be challenged. If you are involved in a night-time accident however, any slight illegality with respect to your lights or reflectors may be regarded as contributory negligence.
The following items are the minimum required, on a bicycle or tricycle, in order to ride it legally at night:
Front Lamp
One is required, showing a white light, positioned centrally or offside, up to 1500mm from the ground, aligned towards and visible from the front. If capable of emitting a steady light it must be marked as conforming to BS6102/3 or an equivalent EC standard. If capable of emitting only a flashing light, it must emit at least 4 candela.
Rear Lamp
One is required, to show a red light, positioned centrally or offside, between 350mm and 1500mm from the ground, at or near the rear, aligned towards and visible from behind. If capable of emitting a steady light it must be marked as conforming to BS3648, or BS6102/3, or an equivalent EC standard. If capable of emitting only a flashing light, it must emit at least 4 candela.
