Trailer Lights Not Working

[Dubz]

I can't seem to find out why my tailer lights have stopped working. I tow a jet ski trailer which one of the led trailer lights got a little water inside of it which may have cause the initial problem. Now I can't get the lights to work again, I have checked the fuse in the back compartment #78, which is still good and I have check the connections at the light module and connections for the trailer light socket with no luck. I think the problem may be the light module, but the only way to get a light module is by purchasing a complete trailer hitch set. My question would be has anyone else had a problem similar to mine and if so how did they repair there problem or if anyone has any recommendations on what I can do to repair my problem help would be greatly appreciated.
