On my wife's '04 ML350, on the headlight switch, if you rotate the switch "backward" as if you're turning the lights OFF, there is one more position past "OFF". Nothing happens as far as I can tell when the switch is in this position.

What is it for?

Standing lights, turn the turn signal switch to 1 side or the other at the same time.

Thanks for the info. I'll have to give that a try & see what happens.

Do it with ignition off.

OK, I tried what you guys said, and it works as stated. The only question I have now is: "What is the point?" Seems to me if you want these lights on, you'd want both sides on, not just the left OR right side. What am I missing?

IF you visited almost any "town" any-where in Europe you would understand.

They are parking lights, select the side to turn on based on what side of a street you park on, it is a little reminder for the folks driving not to run into your car.

Thanks again for the info, guys. It makes sense now. Not sure I would ever need this feature, but at least now I know what it's there for.
