Tail light not working

Hi Tom, check the fuses in the tow vehicle, I had my back turn signal light and brakes lights go and that is what it was. However it blew the new one as well so there must be a short in my wiring somewhere.

Thanks Pete.    Checked fuses in both TV and Rpod.   Took tail light off and checked wiring and followed it best I could.    Day before we drove through a flooded street after a huge thunderstorm and took some water under the pod's door; and we have axle risers.    Could not find cause.    Drove around for two days without back light, and then thought maybe wet and shorting?     Bought a tube of dielectric grease and put it on wires and the electrical connector.    Lights came back on a few hours later, I'm thinking the driving and the sun and wind may have dried it out?     Anyway thanks for responding.     Tom
