I noticed a problem recently that started a month ago on my 1992 500E. Let me describe what I have found and see if any W124 owners have had the same experience.

The Lamp Out indicator on the dash came on when I would back up and hit my brakes....So I didn't worry about it for a while.
I have the car interior removed except drivers seat but have not touched any wiring and only drive it for specific reasons, such as to take it to the dealer yesterday.

I did finally check it and found all brake lights (corners and center)
seem to work fine. Reverse lights also both work fine....

Last night I noticed the Left headlight, L running light, L tail light did not work. I checked the fuses, they seem to be OK, even took them out.

Turn signals (f/r) work.

I next turned on just the running lamps. Right side was OK, Left front was off, left tail was off, left rear corner was on.
I took out the tail lamp assy. on both sides and noticed a faint glow to the right rear brake light.

Could it be the switch on the dash going bad?

Thanks for any advice.
