Now that the winter nights and early mornings are darker cyclists should make sure they can be easily seen at night on the road. Being visible is the best way to stay safe.

The minimum legal requirement for riding a bike at night in the UK is as follows:

A front lamp showing a white light, positioned up to 150cm from the ground and facing forwards. If capable of emitting only a flashing light, it must emit at least four candela (a unit of light intensity, comfortably exceeded by modern lights). If capable of emitting a steady light, the light must comply to BS6102/3 standards
A rear lamp showing a red light, positioned between 35cm and 150cm from the ground, facing rearwards. If capable of emitting only a flashing light, it must emit at least four candela. If capable of emitting a steady light, it must comply to BS3648, or BS6102/3 standards
Rear reflector, coloured red, positioned between 25cm and 90cm from the ground, facing rearwards
Pedal reflectors, coloured amber, positioned so that one is plainly visible to the front and another to the rear of each pedal.
