ILS Brightness Issues??
The good news is, it's very easy to adjust!.
On top of each headlight towards the rear, there's a plastic screw with the markings up/down and you can adjust the height the light beams point.
Very easy to do!

The lights will keep adjusting as they do but the center point of which the beam shines will remain to what you have adjusted it to.
Yes very easy, open the hood, and look towards the rear of the head light assembly, you will see a white/grey plastic screw that you can adjust with an Allen key, you also will see a marking to turn counter clockwise for up (raise the beam) or clockwise for down (to Lower the beam).
I suggest you park the car approx. 25 feet from a wall on a level surface in order to adjust the beams properly and not have one pointing higher than the other.
The adjustments are on each headlight, so make sure you adjust both to the same level wether you raise or lower them!

It's only when I got a 2016 c300 also with ILS as a loaner that I realized how low my lights were pointing.
After I adjusted them, I'm much happier now with the visibility!

Usually if it shines just below the license plate of the car in front you, it shouldn't blind anyone!
I'm not sure what exactly they did, but the headlights work very well.
