The problem is in the ground side of the magnetic tow lights. Take them apart and check for a borken wire to the ground side of the lamp (the base). Could also be caused by corrosion. Check all connections and clean the sockets.

The problem is not in your coach but in the ground to the toad lighting.
Check the ground wire at the plug to the coach. All the symptoms point to a bad ground on your magnetic lights. Also, you might check by rigging a separate ground wire from the ground wire on your tow lights directly to coach chassis. I would spice in a test wire near the lights themselves and run to the coach just to eliminate an internal break in the wire. The wiring on those magnetic lights take a beating. Just some other suggestions to try....
I have a 2'd set of magnetic tow lights; that give the same problems. Doesn’t seem likely it’s the light wiring. Maybe it's the umbilical cord (it looks good, no cuts in insulation). I do drive washboard dirt roads for a couple miles most trips, lots of shaking and dust back there.
As suggested, I'll try a separate ground wire, directly from the lights to the coach chassis frame - but can't get to it until next weekend. Thanks for the suggestions. I'll give an update in a week or so.
