not fishing but boat related.

my guess would be the fuse under the hood for the running lights. just look at your fuse block in the manual for your truck and it'll show which fuse is for your running lights. this fuse is very bad about blowing. we were up at lake erie a couple of yrs ago and a friend stopped by our campsite. his running lights was out so we got the manual out and found the right fuse. we changed it out and problem solved.

it keeps blowing. i've replaced it 3 times now in as many days. thought i had it fixed but apparently not. unplugged before i put in and brought out, turned auto lights off before hooking and unhooking, and i changed the plug and made sure all splices were tight. might be somewhere else in the trailer.

You have a bare wire, making contact on your trailer, or somewhere .also those fuses are normally 20 amp.

I'm pretty sure it's the brown wire.. probably where it goes through the frame

I never unplug my lights when I launch. Have never had a problem. Just never had to submerge the plug

i submerge just right over the fender. so no where near the plug. it only happens when i just pulled the boat out, dropped it in, or possibly when i start with them plugged in and auto lights on.

You you have a bare spot or broken marker light wire
