One practice I try to follow is to unplug the lights before backing
in. The other is to try to remember to plug them back in before
hitting the road. That one's harder.

I had the same problem when racing sailboats..so used a spare pin to
ground a wire from a green LED on the dash. When there was no
trailer..no light. When the trailer was plugged in..the green light
showed. It would flicker and blink if the ground connection OF the
trailer was bad so it was a secondary indication of what the rest of my
lights are doing.
