Headlight Wiper Question

As I work to become more familiar with this model before I make a purchase, as I have inspected potential cars I have noticed something about the 1990-95 headlights that have me pondering:

The headlight lenses have three little "nubs" or pins that stick out from them. I know these are for headlight aiming equipment. However, I'm at a loss to understand how the headlight wipers move freely over the headlights to clean them when they are actuated.

Don't they run into these pins? Are they expected to just move over them?

I'm very familiar with MB headlight wipers on other models, but I don't recall ever seeing a design like this.

yes, the wiper just goes over them. i don't know how effective it cleans because of this as it lifts it off the glass. but the only nub it goes over is the centre one. the 2 nubs along the bottom it just rests on as the wipers should park horizontal, just above the nubs.
On any of the MB models with wipers, I always figure that the owner does poor job of maintaining the car if one of the wipers is out of place. I just saw a local used car dealer with a nice 98 SL500 for sale, and one of the wipers was at the 11 o'clock position.

Why wouldn't someone fix that????

because a motor replacement is $300 for the part plus labour at a rate of $140/hr. if the motor is getting old it will not always park 100% all the time. and moving it by hand will hurt the gears and motor according to MB.
...if you get the Euro Spec lights that have no nubs you also need to buy the euro wiper motor...
that is semi-accurate from what i have read in my parts catalog. though it may not show the US spec lights.

from my catalog there is only a difference between the xenon and non-xenon. you don't need the whole motor replaced, you just need wiper blade and wiper arm assembly.
