I have high beams and all four bulbs work for that. if you flip the lever to low beams they all go out. If you turn the headlight switch off and E brake off I have DRL's. ???????
If I turn the switch to parking/running lights I get the DRL's which look like low beams. ???? but if you rotate it to headlights it has no low beams. And only high beams if you flip the turn signal high low beam to high beam setting. ????
