This Attwood Bi-Color Boat Navigation Light is composed of anodized aluminum that raises the light head for visibility above the trolling motor, anchor, or other equipment on the bow. The 14" straight 2-pin locking collar pole offers a "universal fit" so it can be used with a wide variety of Attwood 2-pin and 3-pin straight or angled bases. This boat navigation light is designed for boats up to 38.4 ft. (12 meters) with its 1-mile 225° red/green light visibility. When not in use, the lights can be removed from the base and stowed to prevent interference with fishing or anchoring.
