I took some pictures on how I wired my LED lights and thought you would like to see how I did it.
After I almost got a ticket one AM on the way to work,,I spent a few hours in the shop elevating mine on the PVC up-rights that are on the sides of the trailer when I got home.
Like this.
The only two splices (per side) that I do have in my wires are where they will not be under water at all when the trailer is backed into the water.
I have a splice in the wires up by the light and also up by the hitch where it plugs into the truck.
All of them are soldered, liquid elect tape, and then heat shrink tubing finishes it off. I don’t know of a better way to do it……..
