    Hey Guys, I have 2012 388. When I turn on high beam, both high and low on passenger side go out. Driver side headlight just work fine. I have checked all the fuses under hood, and visually inspected all wires going to both headlights. Another weird thing that I have noticed is driver signal ( Little green arrow) on dash is blinking fast when turning on the signal, don't know if its related to the headlight issue. Please help!!!

    Sounds like the wiring can't handle the load required with the high beams on. I'd take a close look at the hood harness, especially where it bends, and the connectors for the headlights.
