Is there any way to get the park lights and fog lights to be on at the same time? It only works with the headlights (like you all know), but is there any way?

Noo! On the 123 (at least my two), that didn't work. You had to do something with the wiring to have the parking and fog lights on at the same time.

yeah, that definitely does not work on our cars, is there something special with your wiring, cause parking lights + pull = parking lights

Nutz, sorry but you're wrong this time bud. You have to remove the fuse panel and move the fog light circuit from the headlight fuse to the parking light fuse. This will not damage or put your wiring at risk, but you need to make sure you change the fuse to the proper size. I think this site has more detailed instructions.

Hmmmm!That's odd because all of my MB's do it even
my 6.9 and 450SE with euro lights.Even my old
74 and 75 450SEL's with US lights do it too!

One click to the right on the rotary light switch and
pulling out does not allow this function?Thats weird!

But who knows,maybe they have all been modified to
these Alaskan winter conditions(20+ hours of dark)[xx(]

My Euro Spec does it .... on click right, one pull out turns on front fogs, two pulls out turns on rear fog with front fogs...

My valance fogs are on a separate switch in the map holder....

I looked at rearranging the fuse panel, but decided that was too big a pain in the arse. I, therefore, chose to attack the light switch.

The normal wiring (US spec) of the light switch is that power comes into the switch at connection "30". When the headlights are turned on, power goes out of connection "56" and goes to the turn signal/dimmer switch. If on low-beam, the power then goes to fuses 11 & 13. 11 feeds back to light switch connection "NSE". If the light switch is pulled (for fogs), power comes out connection "N" and goes to the fog lights. Going to high-beams cuts power to fuse 11 and the fogs.

I took the somewhat less than elegant route of cutting the wire going into "NSE" and connecting it to a FUSED (since fuse 11 is now bypassed) hot (positive) feed. This provides fogs at any time. Even with the headlights off, you can pull the switch and use the fogs as passing flashers (they won't stay on, obviously).

I figured there was a way to change the wiring at the light switch, I actually went through the switch looking for a circuit I could attatch the fog lights to but couldn't find one. Just to be clear, did you say there is a circuit on the light switch that allows you do this? If so, could you please explain? Sorry, but I couldn't quite understand what you were saying in that last post.
