I think I am going to abandon my light since it is in an obsolete niche and the inner ring is broken. What I am thinking is to clip the cord on both ends but leave it in place to install a new niche and light once we do our plaster job hopefully next year. For now what I would like to find is some kind of universal niche or light cover to go over the hole. I am thinking some kind of vinyl disk that pops in or expands from the inside against the wall of the niche housing. Does such a part exist?
