I have an overhead light fixture and I need to remove the "cover" so I can change a bulb but the cover is held in place with metal brackets that have to be removed first and they are attached to the main part on the ceiling with flat head screws.
The space between the cover and the ceiling is too small for pliers, and even small wrenches can't get enough grip. (I'm wondering how it was even installed in the first place, tbh.)
How can I remove it? Is there some kind of drill bit that could do the trick?
