The W211 Xenons' headlights consistently become foggy.

My W211's headlights still fog up nearly annually, no matter how many times I get them trimmed and cleaned to a mirror finish. This is really bothersome; is there a protective covering that can stop it? During the winter, it's noticeably different out in the countryside.

apply a sunscreen lotion? It is a component of several lens polish kits.

Looks like you might want to think about getting new lenses. It doesn't appear like you can get aftermarket ones and they're not too hard to swap out. A friend of mine does this every year because the headlights on his fiesta become fogged up. Considering that a dealer would charge £599.00 for a new set of xenon headlights, I'm not sure it would be worthwhile to have new ones.

Sun protection is essential. Reapply every several years using gtechnic C4.

Not a headlamp shield, but a trim restorer—I thought that was what you meant.

Yeah, it's a great sunscreen. In essence, a ceramic covering

The smart autonomous dipping system was standard on my Mercedes C207. Without a doubt, the most impressive set of headlights I have ever used (I've heard the newest model is even better).

Personally, I've had terrible experiences with the Bi Hex headlights on my Skoda Superb.
