Hi. I posted a similar topic a few weeks ago, when my 89 300e driver side headlight would dim every once in a while and would be fixed simply by tapping the lens. Well, following your advice i did find out that the bulb plug housings were starting to melt and i had them replaced. (9004 connectors) however, the problem now is that when i turn on my high beams or the fog lights, the headlight dims to a very faint yellowish color. and even when i turn off the headlights and turn them on again, they are still about 50% weaker than the normal, problem free passenger side light. I've checked all the fuses and they are fine, and the connectors are brand new and show no signs of melting. I am running US-spec 9004 lights 45/65w. I have hit up the headlight in a previous accident but the problem as only arisen recently. Please help..Thanks..

Two things, the connection between the new unit and the wire harness has to be a 100% good solder connection to carry the load. The other thing is the ground. There should be a ground connection near the headlight where a wire bolts to the inner part of the sheet metal. Make sure that is clean and tight.

thanks alot...i will check it first thing tommorow morning...o, i noticed that where the new connectors were attached, the mechanic used some kind of heavy duty plastic electrical tape...does this mean he didnt solder it or is this simply a covering over the exposed soldered wire? thanks...and how does the ground look, or will it be simple to identify...thanks alot..i appreciate all the help..

After you solder in the new wires, shrink wrap them...remember to slide the shrink wrap tube onto the wires first before you connect them!

Also, if you've upgraded & properly installed new sockets, they should have no trouble handling higher wattage bulbs...I've done precisely this on both of my W124s and have been quite pleased with the improved lighting performance

Best regards, Michael
