House/Chassis battery switch lights
The chassis and house battery cut off switches in our Winnebago have miniscule green lights built into the face of the switch. They are virtually impossible to see unless you get your face right in front of the switch and shield the sun with your hand. Being down in the step well makes it even harder. I found it was easy to get a bright red 12 volt pilot light (from eBay) and, after finding the two wires that go hot when the battery was on, hook it up and mount it adjacent to the matching switch. Much less likely for me to forget to shut off the batteries now with the red light shining. Turning off the batteries has become really important now that so many components have computer-based controls that are never really off... If you look REAL close at the coach battery switch you'll see the faint green light on it.
