HID Headlight Flickering Blink Flash

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.

Maybe the problem is the ballasts,

first,you should check your ballast is AC ballast or DC ballast.because quality of the DC ballast is bad,It's the normal things to make the headlight Flicker

Second,you shoud check the operation declaration of the hid kit,maybe you made a mistake for installing and fitting the wires together

I dont know exactly what's happen to your car,but you could check this things,and normaly,it's would not be happen

maybe you need to test canbus ballast for your car.
