I am thinking of installing a weather/water proof switch outside to manually turn on my PC backup lights. The switch would be mounted upside-down, next to the light that illuminates the license plate. This way I have easy access to white light when hooking and unhooking my tow vehicle after dark, and also for quick temporary convenience lighting behind the motor home when putting camp site things away after dark.
Currently when dealing with the tow after dark, the only real convenient white light is the tow vehicle headlights, but they blind me given they are high, inches from my head, and basically shinning in the wrong direction. Holding a flashlight under my arm or a small one in my mouth while working the hardware just is not practical. I tried a strap-on-head LED light once, but it is not ideal. The RV backup lights are low enough from my face, the right brightness, and perfectly positioned to light up the work area properly. A switch next to the license plate light seems the perfect location.
I am currently investigating a good well sealed switch, and also will be discussing with Kermit if there are any concerns electrically. The modification should theoretically take under one hour, maybe even less than 1/2 hour. Constant 12V power is right there at the tow connector. I was under the rear of my PC today and everything is very easy to access from behind the bumper.
ADDING: I found the ideal switch HERE
but with shipping, it is $37.50
Looking at my PC's tow bar folded up in the picture, you see the backup lights relative to the tow bar.
