First you will want to check the right turn signal of the vehicle wiring connector to make determine where the problem is. It's either the tow vehicle or the trailer.
You will want to use a circuit tester like part # PTW2993 to check the pin on your connector for intermittent voltage when the blinker is applied. If the voltage of the vehicle checks out like it should then I would suspect the problem is either that the light assembly isn't grounding properly or it is shorting out to the running lights circuit.
Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare metal surfaces.
If the problem is the tow vehicle then you would want to check the trailer wiring fuses and relays under the hood of the vehicle to make sure none of them are blown and fix as needed.
