This is a beat to death issue but I'm going to post it anyway
My left back light went out after my last trip to Fl and dunking it for 5 days
I've been looking for a tin coated copper harness because the copper wire rots after about 5 years. I'm not putting just copper wire back on there
So I'm going to get a new light and patch it up during fishing season then this Fall I'll tackle this. I'm not a trailer light expert but there's wire on there now I just have follow it and replace it
My biggest problem is finding a tinned copper harness

I would replace the system entirely so your lights are never submerged. Have them run up the guide rails on trailer.

I did that with mine. Works great.

I don't have any guide rails on my trailer nor will they fit

I just chased down a similar short in mine last week. Turns out they stuffed 5' of wire up in the trailer frame instead of cutting the harness to length.

Nearly all trailer light problems are due to grounds. I don't agree about wiring where nothing gets wet - its a boat trailer, it is supposed to get wet. Use water proof connections, get something that solves the ground problem, run LEDs.

That was just in case you wanted to lengthen your trailer.LOL. Some people take no pride in their work and half ass everything.

Good point about grounding. I somehow never could get an acceptable ground through the hitch to my truck chassis, so I made a short jumper using large gauge wire and clamps like you would have on jumper cables and clamp one end on the trailer and the other end to a good ground point on my truck chassis and I haven't had a problem since.

That trailer box looks cool but not waterproof. Most trailer harness are 3 wire and there only 4 lights so why 6-7

Also most harness come 18' I need one longer and tinned copper. I guess I could use my 14 gauge to make it longer

I just got two 100 ft spools of 16 awg tinned wire.
One at $13.89 and one just over $15.00 delivery included.
didn't get it for the trailers but would work there too.

Prices very widely but if you check ever few days you can get a deal.

Thanks @mro where did you get it. Also you will need 3 wires. I may just stick with 14 gauge to last longer

I'm going to look for water proof LED lights. Any suggestions?????

 

[permitchaser]

Did some research and found these at Harbor Freight. LED with epoxy sealed wire

 

[fishnpreacher]

Check the gauge wire used in the light. I bought some once that had 20 or lighter wire in the light....lasted about a month. The harness was 16.....foolish to have bought it

I try to go back as far as I can to use 14 gauge

I agree 100% about tinned wire. I bought 2 strand 14 ga tinned wire from West Marine right off the spool. Got about 50' of it and made my own harness. Bought two LED lights and it has works great the last several years. I got to agree with everyone that a lot of the problems are associated with the ground. I think if I were to do it again, I would just get 3 strand and run an independent ground to the lights rather than grounding them to the trailer. But either way, get tinned wire, it last so much longer than the non tinned crap they sell for trailer harnesses.

I only use Dry Launch lights. Get them wet for years and never have to replace them.
I believe they are #701.
