We have an 95 horse trailer that seems to blow a fuse in the truck that pulls it when you turn on the truck lights, and then we have no tail lights on the trailer. Any suggestions what we need to do to fix this? Right now we just pull the trailer in the day time.

If you can't find the source of the short in the truck wiring, and it's not a continuous problem, NAPA sells circuit breakers that interchange with and fit into the truck's fuse slot. They automatically reset after the short is removed. They also make it easier to find a short without having to change a multitude of fuses while looking for the problem.

If the truck lights work fine without the trailer then it's a short in the trailer wiring. Visually check the wiring and look for places where bare wire can touch the trailer metal. This will usually be near connections or places where wires are loose and can move around. You can also test each wiring circuit with a circuit test light like this one:
