We have not graduated to the Fiberglass camper yet. We use an older pop-up for our outdoor adventures. Last Christmas I found some nifty LED "puck" lights
that are controlled by a little remote. I have put magnets on the back and attach them to the frame of the pop-up when we set-up camp. We also adapted several with Velcro for use inside the camper.
When the 3AM call to the restroom happens I click the remote and lights come on in & out of the camper so we can find our way. The lights I use are adjustable from burn you eyes out bright to a nice glow. It is really nice to be able to see around the camper at 0-dark-thirty.
