Are you getting power to sockets? Make sure you have a good ground circuit
check for power at the trailer connector.
Your trailer tailights are dual-filament, with one being the running lights and the other the brake lights. You need a separate power source from your towing vehicle's brake lights to power them. The easiest way to do this is go to U-Haul and but a set of their trailer towing taillight bulbs for your towing vehicle. The bulbs replace your standard tail/brake light bulbs, and they have two wires coming out of the base of the bulb. One of the wires connects to your trailer's running lights, and the other one connects to your trailer's brake light circuit. I'm trusting that when you re-wired your trailer, you ran two wires from the taillight socket, one for the running lights and one for the brake lights. In some trailers, the brake light circuit also doubles as your turn signals. Good Luck.
If you have a plug for trailer lghts it is probably a short circuit in the socket.
Trailer lights are sold at many stores nationwide. You can find trailer lights at home improvement stores. You can also find trailer lights at automobile repair stores.
Take a light tester and check the pins at the truck side trailer plug. With the truck set for running lights check for power at the pins. If there is power then there is a loose or bad wire on the trailer side. If there is no power then there is a power problem on the truck side.
Tail lights inop all the others are ok Break lights in the same socket are ok / No power to the tail light side of the socket
