the main light switch (located left of stearing wheel on dash board}this has a light bulb in it which even when replaced does not light up---- have looked at 3 simlar cars none of them light up the switch Is this acommon fault and is there a cure--thanks for any answers to this question--syd

The bulb socket in the headlight switch was not used on the U.S. version car. It is used to indicate the rear fog lamp operation. The rear fog lamp is a single bright lamp only on the driver's side. It wasn't used on the U.S. car until recently. You don't have a problem!

I'm a nit-picky kinda guy and I'd like to get the rear fogs functional in my 81 126. Does anybody know where I can order a Euro-version rear inside tail-light assembly and appropriate bulbs. Once I get them do I just plug them in or are there more complications.
