I changed the Burner and it worked when I first fitted it but, when I went for a the first ride I noticed it was no longed lighting.
I'm guessing it is the Ballast is at fault. When you unplug the connector from the side of the plastic headlight cover and connect it again the light starts up for a split second and the Ballast makes its little buzzing noise. It sounds like a bad connection, I know, but I'm pretty sure it is not. In relation to a standard electrical system the HID setup is quite difficult to check, particularly when there is, obviously, no continuity from the Burner.
