Removed the old built-in lights for the eyes, but didn't want to go down the route of patching large holes in the ceiling. Couldn't find any mods that had a fairing wide enough to cover some of the bad sections of the ceiling but I found these and they are perfect! We don't actually use any light at all, but we installed LED bulbs, so at least we have the option. In addition, they are made of glass and fit very tightly to the ceiling. Great product, highly recommend!
