Headlight Replacement
 

I'm having some trouble replacing the headlight bulb on my 1992 190E. The instruction manual instructs you to turn the plastic collar behind the bulb counterclockwise and pull it out. Well, I tried turning it and it just won't move. I thought that maybe it was stuck, so I tried to remove the other bulb and the collar on that bulb won't move either. OK, so I must be doing something wrong. How do I get the bulb out so I can replace it? Thank you very much for your time.

:confused:

Hi Mercedes Guy:

I have a 300E, not a 190, but the first time I changed the bulbs, the plastic lock collar on each light was jammed shut. I think road dust and humidity had glued things shut. I spent several minutes on each bulb twisting and rocking, blowing them out with an 'air' can of computer dust cleaner trying to get them loose. On mine I seem to recall there was a rubber seal that the collar seated against which had also glued things together.

Maybe one of those rubber strap wrenches like they have at Sears would help - just make sure to not turn the wrong direction, or too far, as 10 year old plastic is probably starting to get brittle. I wouldn't use oil or WD40, however, as petroleum lubes might weaken the plastic. I have never tried it, but perhaps a couple drops of baby oil around the collar/headlight interface an hour or so in advance of your next removal attempt?

Good luck - I am sure some 190 owners will have more appropriate advice.
