Lopolight Series 300-039 - Double Stacked Masthead Light - 5NM - Vertical Mount - White - Silver Housing

The Lopolight Series 300-039 Double Stacked Masthead Light is designed for serious boaters and commercial mariners who require dependable navigation lighting in challenging conditions. Visibility at night is essential for safety, and this light provides a 5-nautical-mile visibility range, adhering to federal regulations for vessels in open water and coastal areas.

This vertical-mount masthead light features a double-stacked design that enhances light output while maintaining a compact size, making it suitable for sailboats, fishing vessels, and trawlers with limited mast space. Constructed with a silver anodized aluminum housing, the Lopolight 300-039 is resistant to corrosion from saltwater and UV degradation, ensuring durability in marine environments. The white light output functions as an all-around masthead light, effectively signaling your vessel's position and heading during low-visibility conditions.

Ideal for mariners operating under USCG regulations, this masthead light simplifies installation on standard mast extrusions and provides proper light dispersion across the full 360-degree horizon required by maritime law. Weighing just 2.5 lbs, it minimizes the top-weight penalty that could otherwise impact vessel stability or mast characteristics, making it a practical choice for extended offshore passages.
