my headlight has something wrong, the right side headlight always shut down gradually until an error message showing on the dashboard, but it can be back to normal after turn it off and restart it again. Guys, do you know if the light bulb goes wrong or the ballast of HID goes wrong?

If the ballast of HID goes wrong, pls adv if DEPO will supply it together with their kit if I place a buy in this GB

thx
