This year the clocks will be turned back to Greenwich Mean Time on Sunday 25 October. As always, at this time of year, we like to remind our readers to ensure they are using their bike lights as the law requires them to.
Here are the basic guidelines on what to consider when lighting your bike.
When must you use cycle lights?
When riding on a public road, cycle path or public place between sunset and sunrise or in conditions of seriously reduced visibility during the day.
What is required?
The picture below summarises the minimum, but flashing lights are now permitted. This is provided they do not flash too fast or too slowly, i.e. at one to 4Hz, are illuminated for most of the flash cycle and of 4 candelas brightness or more.
One white light, marked BS6102/3 (or equivalent), positioned centrally or offside, up to 1500mm from the ground, aligned towards and visible from the front. (In the UK offside is on the right hand side of the bike when facing forward.)
One red light, marked BS3648 or BS6102/3 (or equivalent), positioned centrally or offside, between 350mm and 1500mm from the ground, at or near the rear aligned towards and visible from behind.
One red, marked BS6102/2 (or equivalent), positioned centrally or offside, between 250mm and 900mm from the ground, at or near the rear, aligned towards and visible from behind.
Four pedal reflectors
Four are required, coloured amber and marked BS6102/2 (or equivalent), positioned so that one is plainly visible to the front and another to the rear of each pedal.
These need a rear lamp and triangular red reflector(s).
