headlight issue
My 2011 headlight got water in it also, bulb blew in 2 rides. I removed unit- poured some alcohol into it to try and find where it was leaking-Alcohol is thinner than water. Could not find leak. So I blew it out,then let air dry. New bulbs, then used dielectric grease around running bulb socket and around the rubber headlight cap-to help seal it.
Has not blown yet in next 4 rides, only slight moisture buildup from the heat cycles. Which it drys by the next weekends ride.
