    Recently my headlights have been flickering on and off. I brought the car ('07) to the dealer who did nothing. My local mechanic said it is a transformer problem and I should bring it back to the dealer. He also said it is probably still covered by warrranty. Anyone have any thoughts or info about this? Thanks.

    Re: transformer problem

    The HID headlamps use a power supply normally called a ballast or controller. It is basically a transformer type system with some control electronics.

    You could be having trouble with the ballast, or it could simply be one of the capsules (bulbs). Toyota has a history of problems with the capsules in the Prius. A quick search of this site will give you some ideas. Sometimes the dealers fix the problem without a fight. Sometimes owners just buy new capsules from EBay and do their own replacement. Others have paid large $$ out of pocket. Some have had luck getting Toyota corporate to reimburse the cost.
