A few years ago a flatbed trailer cut a left turn too close to my '03 sedan and rolled across my left front fender. My HID headlight continued to work perfectly but the lens was severely gouged and whole assembly was replaced by the insurance company at about $800. The body shop gave me the old headlight so I removed the little controller thingy. I'm guessing it is some kind of high voltage transformer and regulator. Don't know how often, if ever, these go bad but I'm willing to part with it since I've since sold the vehicle. Any reasonable offer. PM me, or since I don't visit here regularly, email me at tc_brown@***.net

 

the ballast?
