The other day I noticed my headlight was not coming on even though the icon on the controller said it was on. The tail light was also not on but both the brake lights and the tail light flasher worked. I informed Rad and they had me checking connections etc. which were all fine. They just informed me they were sending me a new controller under warranty. I thought it was a bad headlight. I've been riding the bike and everything works but the headlight&tail light. I guess if it was just a bad headlight that the tail light would still work?
