Brass color dome light.

The Mars Dome is a general purpose, surface-mount light fixture with red/white lights for night use, with the added benefit of LED technology. These lights produce a warm white light and are fabricated from the highest quality components to assure long life and trouble-free functioning. Their patented internal circuitry provides consistent brightness and makes them immune to life-shortening voltage fluctuations. Their incredibly low power draw makes them the perfect way to reduce energy consumption on your boat. Latest high-power LED technology provides high lumen-per-watt light, out performing other dome LED lights.
