RE: 2002 A4 Bad Ballast
the igniter actually ignites the bulb
The ballast in an HID lighting system generally has two purposes. It provides the proper starting voltage to strike and maintain the arc, and it regulates the proper current to the lamp once the arc is established.
order it from the parts department, take off your headlight housings and it is screwed up underneath it.. easy DIY!
$680?????????WTF???????????
