2002 bmw xenon headlights not working


3 months ago the left light would light periodicly and the right would always light. Now the left lights and the right flickers but does not light. This happens in all switch settings. there has been no accident or any other expanations.

Is it a gost or bad wiring or a bad switch…what? Help

Almost impossible to diagnose over the net.

Could be a bad connector…or a ground…or switch…or light…It’ll have to be traced.

Could be bad bulbs or ballasts. Brace yourself for the costs of these.

I’m going with the ghost theory.
