The reflector on my fog lights is corroded from a broken lens. I want to put some Hella MicroDE projectors instead of buying new housings. I could mount the projector in the plastic housing on the stock location but I cannot remove the reflector from the housing. The only thing holding it now is the adjustment screw. I tried to remove it by turning it counter clock wise it moved a little but I was not able to remove it . Can anybody help me out?
