Anyone with Euro Light Experience...
 

I've had these euro style square headlights on my 1985 300D for a while now and they've always bugged me because when I try to adjust them, the knobs just won't turn. Something's binding. I'd like to get the headlights all adjusted right. It is the same on both lights. I've opened them up and tried to loosen the nuts on the adjusters but nothing seems to work. Did anyone else have this problem?

These are obviously not the Bosch european lights. They're Depo.

Only thing I can think of is to take the whole assembly apart and re-assemble it and see if that helps. If it doesn't turn in either direction then I'd suspect it's the reflector part that is bound somewhere.
