How to Waterproof Trailer Light Connectors on a Nitro Boat Trailer

Question:

Bought a replacement light from you. It is for a nitro boat trailer, I pulled the light off and it has a black triangular 3 wire connector on the light and on trailer wire. Is there special connector to keep water proof?

What you can do is apply something like Liquid Electrical Tape, # SWC50122, which will insulate, seal, and waterproof electrical connections. I would still recommend wrapping any connections with actual electrical tape as well for extra protection.

Another option is to use heat shrink tubing which is usually available just about anywhere tools and/or automotive parts are sold. With this you would first place the tubing around one of the wires before making the connection. Then use a butt connector to connect the wires. Slide the heat shrink tube over the connection and apply heat as per the directions. This will create a water tight seal as well. And I would still wrap that in electrical tape, too.

I still would recommend you disconnect your trailer connector prior to backing the trailer into water.
