Attwood 5040R7 Red Deck Mount Navigation Sidelight, 112.5 Degree, 1-Mile Visibility, Boats up to 39.4 ft

The Attwood 5040R7 is a red deck mount navigation sidelight designed for boats up to 39.4 ft (12 meters). It uses a raised base to elevate the light above rails and carpeting so the red lens stays visible from the correct sight lines, and a notch molded into the rear of the mounting base lets wire leads pass through cleanly during installation. The light is rated for 112.5 degree visibility at a distance of 1 mile, meeting the visibility angle expected of a sidelight in this class.

The cover is black plastic, and the unit's electrical contacts are stainless steel so they resist the corrosion that quickly degrades unprotected metal contacts in a marine environment. It comes with a 9-watt wedge base bulb installed and is drilled with two mounting holes sized for #10 screws, so no additional drilling template is needed for a standard deck mount installation. At 0.2158 pounds, it is light enough for typical bow or rail mounting without added hardware stress.
