Attwood Folding All-Round Anti-Glare Boat Navigation LightThis Attwood Folding Anti-Glare Boat Navigation Light is built to last in the harsh marine environments with its non-corrosive materials and glass-filled polymer bases. It features a fold-down base that allows the light to swing 180 and can be mounted on both horizontal and vertical mounts. All of the wiring is concealed and protected within the pivoting base. In extreme conditions, if a 12ft./lb. force hits the base, the cam lock releases and allows base to swing down, reducing the chance of breakage to the base or pole. With a two mile, 360 light visibility, this anti-glare boat navigation light is for use on boats up to 39.4 ft.Features: Fold-Down Base That Allows The Light To Swing 180; All Wiring Is Concealed and Protected Within The Pivoting Base; Has Two Mile, 360 Visibility; For Use On Boats Up To 39.4 ft.; Comes With A 12" Black Plastic Pole; Built To Last In Harsh Marine Environments; Can Be Mounted On Both Horizontal and Vertical Mounts; Non-Corrosive Materials; Glass-Filled Polymer Base; Includes a 9-Watt Wedge Base Lamp; Includes Mounts; Specifications: Visibility: Two Mile, 360 Visibility; Installation InstructionsHOW TO INSTALL ATTWOOD FOLDING ALL-ROUND ANTI-GLARE LIGHTInstallation Choose a position near the transom that is accessible to wiring and has clearance below deck.; Place base on the gunwale or deck.
