My brother-in-law removed one of the recessed light fixtures and now the socket for the bulb is loose - so it is impossible to put a light bulb back into it. He said there is a clip of some sort that was used when the fixture was installed and that it can only be done from above so he thinks the whole thing is ruined now . . . The fixtures were in the house when they moved in - they're circular recessed lights that can be swiveled. Is this enough information for anyone to respond? Any help is welcome! My only other thought is to go to Menards and see if I see something similar and ask an employee.
