I gave up on trailer lights many years ago. I have mine on a PT 1x4 that I
bungee to the transom of the boat after I get it loaded. I can then store them
in the garage when I am not towing. If I am just moving the trailer I bungee it
to the frame.The wire to the connector is SJTW hard service cord, not that
silly zip lead. I don't have problems anymore.
