I give every new light we install on our salt water boat trailer a multi day soak test before i bother bolting them on to the trailer, we have gone through so many different brands of "sealed" led lights on our boat trailer, most of them fail miserably. This will be the third set of lights we have bolted on to our trailer. It passed my 2 day soak test in about 2 feet of tap water, so I expect many years of salt water service for this light assembly. The Seasense lights I bought failed this test.
