Yes that's it. I got into it a little deeper after removing the grille and could see what was happening.
The adjustment screw effectively has a "groove" between two "shoulders" on the screw at the outside/torx end. The plastic housing, to which the light is attached, has a hole that is supposed to be retained in this groove. This way as the screw is turned, with the other end threaded into a non movable piece attached to the frame, it will move the housing in or out to adjust the light beam up or down, while still holding it firmly in a fixed position.
The problem was that the hole in my right side plastic housing had enlarged so that it could still push the light out but could not pull it back in, so it was always loose on the screw. I McGivered a solution by removing the screw completely, putting a small washer on the threaded part closed to the torx end, then inserting the other end through the hole from the outside. This provide a means to pull the housing in. I then threaded a plastic M5 nut from the threaded/inside end so it was up against the inside of the housing. This allowed the housing to be moved out by turning the screw.
On the right side I was able to force the hole in the plastic housing back into the groove on the screw and it's working again, at least for now.
Lights are now aligned and all is good. Sorry for being long winded. Thx .
