Excellent lights. Wiring is not Marine rated.

This is the second set of these lights I've owned. Installed the first set on a utility trailer and they work great. Second set was installed on a boat trailer (last year) that sees saltwater immersion. The lights held up well but the wiring began to corrode immediately. The wiring is NOT marine rated as it is not "tinned". Had to rewire the entire trailer again this year to replace the corroded wiring. Should note that tinned marine rated wire is more expensive but for a reason. It can hold up to saltwater for extended periods. So my recommendation is the you purchase this kit for the lights but then also order (amazon has it) tinned marine rated wire in the three colors needed and use that instead. It's a bit more work up front but you will have lights that work a year(s) from now.
