Thought I'd share some information. I failed a recent vehicle inspection due to one of my projection headlight adjusters was broken. My lights are Hella and mounted on an angle bracket behind the fiberglass. There are tiny little "pockets" that the ball end of the adjuster clips into that break. I have attached some images to help see it. I found a replacement set that works on Amazon...

The first picture is a closeup of a good one. Pic 2 is the broken one. Pic 3 is the entire left side set mounted on the bracket. These can be pressed gently on the ball end in a vise or likely using some large slip-joint pliers. I used a vise.
