tail lights won't work

I was hooking up a trailer that had worked fine the day before (wet weather now) and the lights flickered and went out. Now even with the trailer disconnected, the tail lights and the instrument pannel lights won't come on, but I still have brake lights, and turn signals. I looked at the bulbs and a few fuses which look OK. Isn't it unusual for both bulbs to blow? If one went out would it cause the other to not light too? It seems like it would be a blown fuse due to a short, but which fuse? The dash "stop lamp" trouble light is on?

Fuses "look good" makes me think you didn't test them. By test I mean put a multimeter or 12 volt test light to both sides of the fuse to ensure it both receives and transfers power. Your turn signals and brake lights are on the same bulb filament, and controlled on the same wires. You blew a fuse because your trailer wiring sucks and has shorted to ground on the taillamp circuit, which usually is the brown wire. Test properly and then rewire that trailer from head to toe. Pay special attention to enclosing wiring in split loom and securely fastening it to the frame so it cannot move or rub through from vibration using loom clamps and zip ties. Coat your light bulb plugs in dielectric grease unless they have any corrosion, if they do toss them in favor of new. A well designed and protected trailer is a trouble-free trailer. Anything less is what you need to sort out.
