My sled keeps blowing headlights, but at random times. The set I had in there at the beggining of the year had both low beams and only one had a high beam. So on a trail ride both low beams went out, so I switched to high beam which was only one bulb, and it lasted for the rest of the ride. Then I put in two new brand new bulbs, and went on a 70 mile ride no problems. The next morning I was just going down to the like and the lows went out. Switched to highs, and the went aswell. Oddly dash light and tail light have never blown. IS it the reg before I sink 90 bucks on one?
