Need Help.... Trailer fuse blowing when towing at night

[MVR 155]

Ok to address the suggestions, first off the LED lights on my trailer are brand new, I pulled them apart when I messed with it on tuesday and there is no water in them at all (totally sealed). I actually also tried over fusing by 5 amps as well and it blew, the other truck has the same size fuse on its own circuit just like the Hummer does.

I am thinking that the new LED's may have some kind of intermitent short or something, I think Im gonna pick up a new set today and swap them in, if it doesnt solve the problem I think Im just gonna pull new wire through the whole trailer and be done with it.

I really appreciate the suggestions thus far and Im open to any other suggestions as well

Thanks everybody
