I was cleaning the car today and I happened to be cleaning the headlight switch. Twisted it CCW and right side markers turned on. But I pulled on it and the foglamps turned on! As if I could "flash" the fog lamps with this feature. I didn't get to try it with the engine on (see if that worked) so I was curious why the car has this feature?

Also, while we're on fog lamps: While we were searching for a TE back in Jan, we tested other cars for sale (TE also) and some of them had rear fog lamps, but ours doesn't. Or maybe it's just the bulb, but the bulb out lamp on the cluster doesn't light up if I activate it, so I would guess it didn't have this function.

I know in Europe it's standard to have rear fogs, how about in the US for the w124 chassis?

Pat, it's not standard on U.S. models. Bulb out indicator doesn't recognize it because it's not in the original wiring harness that came with it, plus no socket & terminal on the bulb tray. You can install it, if you want

Yes Pat you'll have to wire it all the way to the headlight switch and augapfel is correct, you also need a euro type headlight switch since ours do not lock when you pull it the second time.

Not all, mostly Euro models only. Only one side of the rear fogs lights up, depending if it's a left or a right hand drive.

My car has this also. I don't think it's an anomaly though. I'm more bent in believing that it's one of the features that MB integrated on the 124. At least it's there for us to use if & when we do need it.
