Well, after replacing what is probably a perfectly fine $100 headlight bulb, it turns out the Zenon ballast is out on the driver's side. Well, actually it's out on the passenger side now. I wanted to make sure it was the ballast before buying a new one, something I should have done with the headlight bulb.

Anyways, other than the dealer and Ebay, does anyone know of an aftermarket source for these headlight ballasts?
