I bought a set of these LED trailer lights yesterday at Harbor Freight ( https://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=95974 ). It a nice st of lights but only one thing was found. The package says they are good for various trailers including "boat" but the instruction sheet states that they are Not submersible and that damage may result in submerged in water. Seems like a bit of contradiction here? Anyway, the price was real good for LED lights so I did not return them. I decided that for the price, i could buy a tube of silicon and make them waterproof. I put a bead of silicon around everything that was a joint or opening to the outside. I also removed the foam lens gaskets and used the silicon to foam a better waterproof seal. I can't see any way water could enter now and the total cost was $45. Still cheaper than a boat retailer price of around $60 for a set without the marker lights.
