Answer
normally, it could be three things - bulb is about to go; transfomer is about to go; burner (bulb socket) is bad. do you have moisture in the lense? if so, this could be the problem. I hope it is an easy and economical fix but HID bulbs are pricey (buy them on line - much cheaper than a dealer), the transformer and burner are ridiculously high and can be found used but make sure the parts are guaranteed. If you can't find them, the dealer will charge you around $300 for the transfomer and about $180 for the burner. The bulbs can be found on line for around $50 vs. 130 at the dealer. If you're not comfortable diagnosing and repairing, take your car to a local collision repair shop. They'll normally do this much cheaper than the dealer. But before you start buying stuff I would wait until the bulb actually goes out!
