A light’s brightness is measured in lumens. How many lumens you need for your ride will depend upon whether you are riding on lit or unlit roads/terrain. A good rear light would ideally be 10 lumens or more. This is bright enough to be seen without dazzling other road users. For front lights, around 500 lumens should give enough light to illuminate the darkest lanes, on well-lit roads a lumens output of around 150 should make sure that you are seen without dazzling others. For off-road trails and unlit pothole-ridden lanes front lights of between 600 – 1000 lumens should provide enough light.
