We have a 2006 Saab 9-7x with the 4.2i engine. We notice almost every time we start the car, a few minutes after the car starts or when we start moving the HID headlights flash, blink or flicker for a split second. Sometimes it happens once and other times is happens quite a few times. Not really a big deal, but sometimes one of the headlights will go off during this flash, and we have to turn the lights on then off again to get it lit up again. This could be a common HID question but I thought I would post it in Saab 9-7x first.
