Powerful lighting with a sleek design. These stylish lights are made of 316 marine grade stainless steel, a highly anti-corrosive metal. This grade of steel has an increased resistance to corrosion, perfect for the marine environment. As you know, LED lights outlast and out shine regular incandescent bulbs. LED lights use up to 90% less energy; these Livorsi nav lights only consume 1/10th of an amp at 14 volts. This means a longer life and less rigging time switching out lights. These LED Nav Lights flush mount onto the fiberglass surface vertically to allow the light pattern to be unobstructed from view.
