Lol I would be scared to drill into my roof.
I was too, but I don't think the holes would be too hard to cover if the light were removed. The hole could be filled with silicon and a strip of automotive vinyl wrap placed over the hole to cover. Certain colors would be easy to match with vinyl. Probably would not be noticed from the ground.
When I installed mine, I per-drilled through the first 2 layers and used large self-tapping screws so I did not have to drill all the way through and use a nut. They have stayed tight with no issues.
