I need to replace burned-out light bulbs in a ceiling fixture. I tried to remove the cover of the light fixture and it does not move. After much trying, the whole thing came down. Meaning the fixture body is stuck in the cover and I cannot access the socket. Instead of working on that on top of a ladder, I disconnected the wires. I have the light fixture on my countertop and no amount of pulling, tugging or prying will separate the pieces.
How do I solve the problem?
