Removable bi-color lights are ideal for boats with casting decks on the box. Unlike conventional bi-color lights that can stand as high as 2" above the deck, removable bi-color lights can be unplugged and stowed while fishing. This leaves only a small, flat topped base. Longer lengths are designed for use with larger trolling motors. 17 3/8" longBlack Plastic3/4" Diameter Anodized Aluminum TubeRequires 2-Pin Mounting BaseGold-Plated ContactsCertified For Use on Sail or Power Driven Vessels Under 12 Meters (39.4 ft.) in Length
