Nine of these used to cover the recessed LED lights in the attic. Although the lamps claimed to be able to be installed in direct contact with the insulation, I noticed that on very cold nights in the mornings, condensation formed on and around the lamps in the room. I bought these covers and installed them on the headlights. I covered everything with thermal insulation and the next cold night there was no condensation at all on the headlights. These cases fit perfectly even in hard-to-reach places and can take a beating as long as you install them in hard-to-reach places. I would recommend these cases to anyone.
