Looking to buy a GOOD helmet light system. Proabably HID, just haven't decided the best course of action. Prices vary greatly. I've heard good things about NiteRider and the ARC by Light and Motion. I'm leaning towards the Trailtech dual light system though, for the combined spot/flood. http://www.trailtech.net/helmet_mou...ight_kits_1.htm Who has some real world experience with any of these, or anything else that works well?
