This heavy duty, fully waterproof dome light is designed for utility use in boats, cars, trucks, and utility vehicles of all types. Made from strong ABS plastic, the lamp features a powerful array of super bright 3528 LEDs, arranged in a circular pattern behind a fresnel lens. Installation is easy: twist to remove the waterproof fresnel lens lamp assembly and install using the included hardware. Directly wire to your 12 Volt electrical system. A side mounted rocker switch operates the lamp. Unlike temporary puck lights, this lamp provides a very bright light source, well in excess of standard incandescent bulb dome lights.
