Attwood 5040G7 Starboard Green Deck Mount Navigation Light, 1-Mile 112.5 Degree Visibility, Boats up to 39.4 ft

The Attwood 5040G7 is a starboard-side, green-lens deck mount navigation light built for boats up to 39.4 ft (12 meters). Its raised base lifts the light above rails and carpeting so it stays visible from other vessels, while a notch in the rear of the base lets wire leads pass through cleanly during installation. The black plastic cover and lens use a twist/bayonet lock design that secures firmly to the base, sealing out water from the lamp and hull while also concealing the mounting fasteners for a clean finish.

Each 5040G7 light delivers 1 nautical mile, 112.5 degree light visibility, meeting USCG requirements for a starboard sidelight. It comes with a 9-watt (#906) wedge base lamp already installed and 7 inch wire leads for connecting to a 12 Volt DC power supply. The light mounts directly to the deck using two #10 fasteners (not included) through pre-drilled holes in the base, and stainless steel electrical contacts resist corrosion in the marine environment. Because this is the starboard (green lens) light, it is not interchangeable with the port side; Attwood's matching red-lens light for the port side is sold separately as part number 5040R7.
