Expert Reply:

A submersible tail light can let water in, there is usually a hole at a low point so the water can drain out. A waterproof light should be sealed to keep out water.

For either type, you would also want to seal out water where the tail light wiring splices into the trailer wiring. Shrink tubing works well for this. You can also wrap up connections with electrical tape. Or you could use a combination of liquid electrical tape, # SWC50122, and regular electrical tape.

Ideally, if you have a trailer that you need to back into the water, you would first disconnect the electrical connection between truck and trailer, and then back up to launch or retrieve the boat.
