i've figured it out
 

Ever wonder why there are two settings n the head light switch when you pull out to turn on the fog lights?

Since these cars are made in Germany, they use the same pieces that they did/do on the SLK. This second setting is for the rear fog light that's supposed to be below the rear facia for extreem for. This way someone can see you when they come up behind you in thick fog.

Wonder how easy it is to put one on here?????



The two settings to the left are for when you are double parked.
