On my 2007 750 LI I cannot figure out why my drivers light won't work properly.
What is your question?
The halos work on the driver side but no low beam not even when I put the highbeams on. The passenger side was nobody has messed with never gets the halos on but the low beam and highbeam work. I bought a new $120 low beam bulb for driver side. It is still did not go on . Could it be the ballast for the light.

Hello, The ballast for HID lights can fail, but make sure there is power to the ballast before replacing. If the ballast is powered, but is not delivering sufficient power to the bulb, that is probably the issue. For reference, you can check the voltage on the passenger side ballast electrical connector, and ensure they are the same.
