Maybe I posted it to the wrong Forum (DIY Guide), so I put it here again.
Just to share how to change the headlights for drive into other countries (UK-Germany):You can make the cut of lights flat by doing this.
Mine is a 2008 Xenon without adaptive headlights.
Open the cover on top of the headlight.
Pull or push the white lever up or down until you hear a small click!
Do it gentle, the part seems not solid.
Your lights should be like this at the beginning (mine is a RHD so the left side is high).
and after moving the lever on both sides, the cut become like this.
If you find the lever, it is a 1 minute thing.
Hope this helps someone.
