This retro front light is smaller than most, which in my opinion, makes it more useable and neater. Probably not suitable for a big Dutch bike, but on everything else it looks great. Works especially well on smaller frames. 

Fits behind a caliper brake on the fork crown. Most bikes have a hole through the crown so if you have different brakes, just get a long bolt to hold the light in place.

3 LEDs give a 10 lux output, with a built-in reflector. Simple On/Off setting. The housing is chrome effect plastic. Batteries included (2xAAA batteries).
