Combination Masthead & All-Round Navigation Light
Keep your vessel legal and visible on the water with this USCG-certified combination masthead and all-round navigation light. Designed for sail and power-driven vessels up to 20 metres (65.6 ft.) in length, it delivers 3-mile visibility — meeting international COLREGS and U.S. Coast Guard requirements for nighttime and restricted-visibility operation.
The rugged construction pairs a chrome-plated zinc alloy top with a black plastic base and a ¾" anodized aluminum tube — built to handle the marine environment without corroding or fading. Clear lenses maximize light output, and the fold-down, adjustable-angle mount makes installation straightforward on most mast configurations. Plastic adapters are included for both flat and "V"-type mounts, with a notch for clean through-base wiring.
