Lopolight Series 301-011 - Masthead Light - 5NM - Horizontal Mount - White - Silver Housing

The Lopolight Series 301-011 Masthead Light is the gold standard for vessel operators who demand reliable, regulation-compliant navigation lighting in all conditions. As an experienced boater, you know that a quality masthead light is non-negotiable—it's your primary all-around white light that tells other vessels your heading and position from five nautical miles away, whether you're running offshore or through busy coastal waters. This horizontal-mount configuration positions the light at the highest point of your mast, exactly where USCG and international maritime rules require it for proper visibility and collision avoidance.

Built with a durable silver housing and engineered specifically for marine environments, the Series 301-011 delivers the 5-nautical-mile visibility range that professional mariners rely on. The horizontal mounting design ensures even light distribution across your vessel's deck and maintains the 360-degree arc mandated for masthead lights under international maritime law. LED technology keeps power draw minimal while delivering consistent brightness across the full visibility range, a critical advantage when you're running extended offshore passages or relying on battery power during extended operations. Weighing just one pound, this light won't stress your rigging or create undue top-weight that affects vessel stability or performance.

The Lopolight Series 301-011 is ideal for sailboats, motorboats, and commercial fishing vessels where regulatory compliance is essential and downtime is costly. Its horizontal mounting configuration works seamlessly on standard mast installations, whether you're retrofitting an existing rig or outfitting a new vessel. If you operate at night, anchor out, or transit shipping lanes, this masthead light is a critical safety investment that meets USCG and COLREGS standards while delivering the reliability that keeps you compliant and visible on the water.
