After fitting my Philips X-treme Power Bulbs today. I tested them out this evening. The headlights seemed to be all a little low on dipped. And the full beam bulb I found wasn't sitting in correctly. That explained the LHS aiming at the floor. I tried to use the 2x adjustors on both sides gently turning and got a bit of movement and then nothing. They stopped moving and cant seem to get anything out of them now. I did hear them clicking as I was turning it but was moving at the same time. Im guessing the crappy plastic adjusters are bust! Is this common and is it a cheap fix? Wheres the best place to get a decent job of a full headlight check and set up? Im guessing the Stealers?
