Im lost here, are they HID's? We need more info. Are you sure its the highbeam and not the low? Is it the inner light or the outer that are giving you an issue? What year is the car? Sounds like the wiring has been played with, and if so your screwed trying to get the problem solved over the net. Someone who knows how to decipher someone elses wiring mess needs to actually be there to look at the car.
