Re: [VAC] clearance light problem

[Dr. Gerald N. Johnson]

Its not usually lamps, its usually corroded lamp bases and lamp sockets
that keep RV lamps from lighting. I'm thinking of hunting up some of the
grease Ford used in my trucks for lamp sockets to keep them clean after
cleaning each with a good brush (power removed).

I suspect that when you tightened the license plate lamp that you caused
a ground that blew the fuse in your tow vehicle.
