Have a wierd situation,
Couple of days ago, Left headlight was dim as I turned on the switch, Would go bright as I drove off. Thought maybe loose fuse. When this occured, The external light indicator light on the dash came on and the high beam indicator also lighted up. Nothing wrong with the fuses, etc.

Few days later (to cold to fully check out !!!) Lights went back to mormal operating mode, No problems.

Tonight , The headlights went totaly dead, everthing else OK, Fogs, running etc.

No Low beam , No high, no heads what so ever.

Main exteranl indicator light ( right side of dash panel) on dash fully lit, and also the high beam indicator lit fully.

Fuses ok, Wiring at bulbs seems OK,

Pull fogs on the switch OK, No change when I flash high beams, No heads of any kind

You guys have a thought?

Thought maybe main switch is out or main lead to switch maybe burnt but didn't get a chance to look. ( Dark and cold in the garage.

Thought I'd check into it further Sat during the day.

2 possibilities come to mind.
The plug bodies have melted at the bulbs, losing the ground circuit connection.Very common with hi watt bulbs.
or the lamp failure module is open circuit.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.

With the lights on do the fuses power up?? If the fuses get power then headlamp switch & combi(turn signal) switches are ok!

Great call, Ground connectors burn't through on the bulbs.

DOC, Good troubleshooting tips.

Thanks to both,
