Buying guide
How many lumens do I need?
For daytime visibility, 100-plus lumen front and rear lights are generally sufficient. For urban riding in the dark with some street lighting, aim for at least 400 lumens at the front. For unlit roads at night, look for 600 lumens or more.
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.
