I have been contacted by a constituent who has asked if it is possible for the cycling Commissioner Andrew Gilligan to make the lights on bikes, especial the back light, a regulated size as he says some you will see is very small and are not very bright? My constituent feels that this may reduce cyclist accidents.

Answer for Lights on Bicycles

Answered By: 
The Mayor

You raise an important issue relevant to improving cycling safety and I strongly advocate the use of bike lights at night by cyclists. Bicycle lights are already subject to national regulations (the Road Vehicles Lighting Regulations 2009), which are set by the Department for Transport and not at a London-wide level. 

The rules on rear lights are quite specific: "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."

As such, this is not something the Cycling Commissioner can directly influence, though we will continue to promote the use of bike lights.
