Is it for night riding in the woods ect or just being seen out on the roads ect? If its road ridding ext go for the exposure flash and flair kit comes with charger ect i just paid £75 full the full kit from evans cycles awsome lights realy realy bright like you wouldnt believe and fully water proof, or if its riding off road go look at the other exposure range me myself im going for a diablo its about £200 but it is an awsome piece if kit! Had one on demo in the winter before xmas! Exposure all the way imo one of if not the best if not the best lights for bikes...
