Any thoughts on making a better waterproof connection with your side trailer clearance lights as mine never last very long with the standard blue plastic crimp wire connectors they recommend you use.
Plastic Electronic device Electrical supply
I have rewired a lot of trailers with new LED lights, liquid electrical tape, and heat shrink but for some reason the side clearance lights always seem to die first and looking to make a better longer lasting connection!

Guys am having no problems running my main trailer wires (2 on each side) back to my main trailer lights as they work properly. I am having problems when you try to splice in / or connect in 2/3 clearance lights on each side of my trailer to give me reference at night for backing up and just seeing my trailer in my side mirrors as I motor down the road! They always work when first installed but are usually dead in 6 months to a year which points to a problem with the electrical connection somewhere!

Just so you know, all my wire to wire connections are twist wrapped, covered in Liquid Electrical Tape, then covered in heat shrink, and more LET on both ends of HS.

I got what you are saying, I think you missed what I was trying to say. Where you would normally use the clip to the brown wire, run a full length wire from the side light to the front of the trailer and then splice in there. That way your connection isnt getting wet each time you dunk the trailer. Same thing with the ground. The ground doesn't have to be right at the light fixture which when gets wet can get corrosion between the bolt and the trailer. Run a wire to the front of trailer and have the ground in a dry spot. You might be able to clean your grounds and it be the only problem.

You are going to have more wiring along the trailer beams, but the connections will stay clean. The only other issue would be quality lights which I am sure you are already using.
Ahhh now I understand! Thx JPizzle

Got one more question JPizzle! If I run ground wires for the 4 clearance lights and 1 ID bar back up trough the trailer to the main ground on the front of the trailer, that would be quite a stack of connectors to ground in one location. Should I put the 6 connectors in the same place up front near the trailer hitch and tighten down on the galvanized part of the aluminum trailer?

You can splice in prior to the front of the trailer if you want with the step down splices just stagger if you want, just more connections. https://www.westmarine.com/buy/ancor--step-down-heat-shrink-butt-connectors--P015982408

Or you can put one of the non metallic electrical boxes and mount on trailer to house a bus bar for the connections. Seems like a lot of excess work but you only have to do it once. I just have my ground by the coupler.

After looking at all my options JPizzle I think I am going with this simple Junction Box https://www.etrailer.com/Accessories-and-Parts/Spectro/38656.html as I am tried of messing with trailer lights every year. I will install the JB up front on the trailer high and dry so it should never have any water intrusion!
