The nights might be getting shorter already but that doesn't mean they are actually 'short'. In prime commuting times in the morning and the afternoon, it is still pretty dark and if you don't want to get run over by a sleepy/distracted car driver, you'd better equip your bike with some decent bike lights so you are visible from all possible angles.
This little bike light really is tiny but does pack a punch for it's size. We've kept everything as small as possible including the battery especially for the road boys where weight is paramount. Compact powerful bike lights for a long time road and mountain cycling.
