Boat trailer lights are critical and under-discussed components. It seems that trailer lights fail at the most inopportune times. Don't risk getting a ticket or in an accident because you neglected your boat trailer's lighting. Most light fittings are vehicle types with incandescent lamps. They are easily flooded and waterlogged, with resulting burnout and failure. Moisture is the enemy of all electrical systems and connections. Water quickly and easily corrodes electrical connectors, and can wreak havoc on lighting systems that were seemingly working just fine. We carry complete trailer wiring kits, lamp covers, lenses, bulbs, light bars, plugs, pin connectors, side marker lights, low profile lights, clearance lights, waterproof lights and more trailer lighting components for all boat and utility trailers.
