I changed the headlights in my 2002 V70XC last night to a HID conversion kit. This kit is USA made and promises no codes due to the lower voltage draw. They are plug and play type lights. The light up fine but I get a flashing yellow warning light now on my dash. Could this be from the lower voltage draw. I've heard of this happening but the company assured me that it would not. I do NOT have any messages on my message center either. They are really bright white lights and I really like them but hate something flashing at me. I will call the company again today too. Thanks.
