I heard good reviews about this light but in reality it wasnt so good. Its very bright, which is good. The problem is that it falls off the bracket when you go over a bump. I smashed mine to bits within days. Tried to return it and at first they would not return it, saying the fault was mine. This is not the case, I read other reviews that had the same problem.
Just be careful, if it falls off at night without you knowing.... you will be playing with your life.
