If the running lights do not work on your trailer it is very likely a bad ground; check your running lights to make sure your grounds are attached to bare metal surfaces and free of any paint, dirt or corrosion. It also could be corrosion on your trailer plug, as corrosion can interfere with the signals getting through the connectors so if it is present you are going to need to replace the plug with # HM38134.

I have added a link below to a help article on trailer wiring for you to take a look at which may also be of use. Additionally, to help prevent any type of corrosion in your connector, and increase its durability and lifespan I highly recommend using Dielectric Grease for Electrical Connectors # 11755.
