The Nyx is a small fender rear light. The light has a special designed integrated Z reflector, which means there is no need to place a second reflector on the bike. The lamp with the reflector can be mounted at an angle of 15 degrees. This and the very flat design ensure it aligns nicely with the fender so it doesn't stick out. It can be mounted very easily with just one single bolt on the fender, or a clamp can be used to mount it on the seat stay. All the lights have French and German StVZO approval.
