Thanks for the input. I think the battery operated LED with motion sensor activation is the best and easiest solution. They make one that only works in the dark. I didn't like the idea of opening up the ceiling or wall panels to rewire the light.I also have to figure out a way to turn on a cabin light in the dark when you step into the trailer. The switch is in the main electrical control panel located under the TV which is a about 3 feet from the door. Again...stupid design. My old trailer had a switch on the wall just inside the door which made it easy to find and switch on. The designer of this rig obviously never owned a TT before.
