I have a set of Xenon HID Headlamps (6000K) installed on my MC and recently both headlights refused to turn on. The HID's were already installed in the car when I purchased it. Hopefully it's an easy fix but does anyone know what the cause of the malfunction may be? A few months ago the passenger side headlight refused to turn on but the driver's side was fine. Now both refuse to function... thank you for your help in advance.
