I've had cars with Xenons before but in the W211, I seem to get a few people ahead complaining I have not dipped my lights. Of course I can easily prove I have dipped my lights but I'm wondering if they might not be aligned correctly. What changed today is for the first time not only an on-coming vehicle flashed but an artic - which made me question it. It is soon to go in for a service but until then, I wonder if this is standard issue on a W211 with Xenons, or are these people just knobbers. They seem to be the right height when shining in the garage, and obviously being Xenons, they should be auto-levelling etc.
