Lamp Warning problem solved one more time
I was having a strange Lamp Warning issue that showed up as a number of odd faults.
When I would shut my car off after running with the lights on, the lights should come on and stay on for a minute or so to light your path once you shut the door. Well in some cases only the lights on half of the car would light up when other times they all would work as normal.
Then some time later, there was a strange problem when I turned my lights on. As soon as I moved the head light switch to the first position the have just the running / parking lights on, I would get the Lamp Failure warning. When I would look at all of the lights, they were all on. It took me some time to notice that there was a delay for some of the lights to come on and by then I already got the Lamp Warning.
The last thing to happen was that the running/parking light on the drivers side would not come on until I turned on my fog lights. It was acting as if they were shorted together. If I turned all the lights on fast enough, I could avoid getting the lamp warning.
I replaced my headlight switch and all of these problems went away. The switch must have been failing over a period of time and getting worse over time. Some times the circuit would be open and other times shorted to a different contact for another light. The new switch works great and all faults including the ones after I leave the car have been corrected.

I think i have the same type of problem with My passanger side break light
as soon as i step on the break the "lamp Defective " lights up on the dash. Ive tried new bulbs and socket but to no avail. when I wanted to buy a new tail light assy it was $118 bucks but no returns (on Electrical parts) the guy at the parts window said it maty be a switch? the breaks light itself works but the "Lamp Defective message stays on. any body got a clue whats up???
E320 2000 4matic, once the light malfunction comes on. The front power seats and front power windows don't function until I clear the codes or I remove the #16 fuse under the hood for the left side and the #1 fuse under the back seat for right side.
Does anyone knows how to fix that problem permanently?
PS: actually all the lights are on.
Thanks!
