Helpful Expert Reply:
It's very possible you blew the trailer running light circuit fuse on your vehicle. You might check that first. Next likely scenario is that you have corrosion on the running light circuit pins of the trailer wiring connector you have as well. Clean that and that should take care of it.
I also attached a help article on trailer wiring for you to check out as well.
