Ive recently realised how poorly adjusted my xenons are. Considering they are meant to be considerable better than standard Halos, mine only seem to pitch about 10ft from the bonnet . Now I think they need adjusting, but after a little surfing, seems that lowering the car messes the system up?? I dropped mine 50mm a good year or so ago, and havent noticed mine auto adjusting (moving up and down) since, so think mine r playing up. Now, I also know there are some manual adjusters on the lights that can change the horizontal and vertical pitch. Is this easy enough to do?? or are there some other 'tricks' I can do to make these better??
