The right headlight on my 300D 2.5 keeps going out. The bulb is fine. The cause seems to be that the plug which the bulb plugs into has rust in its slots. I can get the headlight to work for several days by working the bulb's prongs in and out of the plug vigorously about twenty times. But then sooner or later, the headlight goes out again.
I'll have the cable replaced eventually -- that can hopefully be done without replacing the entire wiring harness. In the meantime, is there some product that can be sprayed into the plug's contact slots to remove the rust and improve the quality of the connection?
Thanks, Geoff
