"lamp defective" comes on when headlights turned on/off - ??

everytime I turn on the headlights, or when i turn them off and kill the engine/pull the key out, I get a "lamp defective" message. I can reset the message via the R button on the dash. I have checked all bulbs and they seem to work fine. I confirmed that I have H7 lowbeam bulbs.

What can be causing this? any solutions? thx

OK, this has always been a bit of a problem with 210's in particular. Yes, common sense says "check all the bulbs" and that's been covered pretty well here. Just to add my 2 cents to that, a big problem is the small inner front lights ("running" lights as they are referred to), these are in the 2 small inner oval lights where the high beams are, which are very dim compaed to the actual headlight bulbs. The front side markers can cause this too, the amber lights on the side of the front bumper. Then of course the tail lights, license lights, etc. MB did have a kit of sorts that's supposed to help keep those front running lights lasting longer, but if they are both working, and everything else, you have some weird problem maybe with the failure monitor, or possibly you just have an incorrect wattage bulb somewhere, or a resistance on a bulb is incorrect, as though a bulb is "on the way" to blowing out. You haven't done something like swap in Xenon bulbs? Or higher wattage or something weird like that? Halogen tail light bulbs? LED's?

let me know if the problem occurs with the light switch in position 1 or pos 1and 2. also please check all your tail-light and side markers for correct and uniform wattage ratings..be careful, i have seen similiar bulbs with the same rating but different manufacturers cause this problem. remember there are 2 tail marker bulbs per side -left side shares it with the fog lamp.
