Stainless Steel Compared to its 55-watt halogen competition, the Surface Mount LED Docking Light draws a fraction of the power while producing a brighter output. At 1.2” thick, the lights are designed to be mounted directly to the surface of the hull with only a small hole for wiring and three (3) screws for attachment. Only the highest grade Stainless Steel and aluminum components are used. The rubber gasket provided creates a barrier that protects your hull from water entry, ensures the light is watertight and keeps all electrical components fully sealed. Backed by a 10-year warranty.
