Hi guys Been having some problems with my xenon headlamps. When switching them on, the right headlamp flashes and then goes dead. after swtiching on and off a few time, it lights up as normal. I took the car to an auto electrician who said it was the headlamp switch, which I then changed. I still have the same problem so I took the car back. They now say its the ballast which shows some water damage and I should replace this. Could a damaged ballast cause this problem?
