I was adding a half dome LED light over the sink area of my OFF-ROAD POPUP trailer.
I had to cut-out the hole for the assembly in the ceiling and then using a fish tape punch a hole from the ceiling fixture to the side wall where I could find some 12VDC lines. All went well and was cleaning out the ceiling areas of residue from cutting and poking around.
Just a bit later I went to the shop for some screws to mount my junction box on the side wall behind the valance curtains. When I came back into the trailer I noticed this small orange looking dot on the floor. Sure enough it was coming from the dome light area. I had penetrated the roof with my drill and the orange dot was the sunlight shinning thru the hole haha...
Couldn't believe I did that... I guess we all do something like this one time or another...
