Buying guide
How many lumens do I need?
BikeRadar says a 200-lumen front light should be enough to be seen on lit urban roads, while 300 lumens will light some of the road ahead. For unlit roads it suggests a minimum of 600 lumens, and 1,000 or more for tricky terrain or high speeds. For the rear, 20 to 100 lumens is a good bet, with brighter rear lights suited to daytime use.
Front and rear, or do I only need one?
UK law requires a white front light and a red rear light after dark, so you need both, even if the front light is far more powerful than the rear.
Steady or flashing mode?
Both are legal in the UK. Flashing mode saves battery and can attract more attention in daylight or dusk, while steady mode helps other road users judge your distance and speed more accurately in full darkness.
What is brake detection on a rear light?
Some rear lights sense when you slow down and automatically brighten, similar to a car brake light, which can make you more visible to traffic behind you when you decelerate.
