I think im about done with the Acerbis diamond, i threw in 55w bulbs and it drained my battery in about 30 mins!! You cant really see much with the 55w anyways, so im going to get a new headlight. what sucks the least juice but is the brightest light? does that make sense? I am now running a fan also on my SMR so there goes more juice, but I need something so that way I dont have to put the bike away after dark!! I know this has been covered in a few spots as in whats the best headlight, but I really need something that doesnt suck alot of amps and runs REALLY bright! I live in the woods and a raccoon in the middle of the road is about as bad as a headon!
