The sockets on my old 240 are very touchy when fitting a bulb and I actually had to add some additional material (tin foil) around the exterior of the bulb to make it fit snug.

Could be the bulb holder is just getting a little corroded. Try cleaning it with some emory cloth perhaps.

I have a right front marker that's intermittent on my 92 330D. The dash indicater comes on, I ignore it for awhile, it goes out. Someday I'll check the bulb/socket contacts. If it was more than one bulb acting up it would be a pain to track down.

Hi Bernie.

I don't know if it is the same system as
is used in the w123 but on my 83 TDT the
bulbs where loose.
I solved it by bending the metal tabs out more
so there is more tension on the bulb.

Also make sure you use Euro spec bulbs.

Hope this helps.

Louis.

Brake light went out, dash indicator didn't come on... does that mean the bulb that's suppost to warn of dead bulbs is dead?
