hey guys so heres what happened, my passenger side headlight stopped working and i was told its the ballast so i bought a d1s aftermarket kit and i swapped the bulbs for both headlights and the ballast for the right side, it was working fine but i still kept getting the low beam right error code so i went and got some error cancelers and that didn't do anything, so i left it like that until today the headlight stopped working does anyone know how to fix this?
the bulb and ballast do work if i give it power from 12 volts it works fine. i searched everywhere but cant seem to figure it out.
thanks
