Dumbest thing to put on an RV?
I could give you at least 3 that are dumber, but I won't because I already put them on mine.
I installed this one on mine under the awning in the middle curb side. May put one on road side above hookups. My brother's Big Foot class C has one there and he loves it. Help full when boon docking after dark or setting up in a dark campground.

Replaced bulb with one of these:

Lens is directional make sure to put the base in correctly so the lens mark "top" will be on top when installed. Directs light down but can still be irritating to neighbors if parked close. Always good to respect others.
The real reason I installed the light was to cover a hole in the side of the RV that I made with a screw that was too long when installing a Light fixture in the bath above the sink.
