After 3 years you've finally had enough?
Joking aside, are you still using the original bulbs or are they aftermarket? Is it both sides or just one? After they both come back on, do you notice any flickering?
While issues with ballasts and bulbs have been documented in the past, if both sides are doing the same thing, I would suspect an issue with the LCM. What kinds of diagnostic tools to you have available?
