Lopolight Series 301-009 - Double Stacked Port Sidelight - 2NM - Horizontal Mount - Red - Black Housing

The Lopolight Series 301-009 Double Stacked Port Sidelight is a compact, dual-output navigation light engineered for boats and yachts requiring reliable 2-nautical-mile sidelighting. This red port sidelight features a horizontal mount configuration with black housing, delivering the precision brightness needed for COLREGS compliance during low-visibility conditions and nighttime operation. Lopolight's reputation since 2004 is built on delivering elegant, space-efficient solutions for vessels of all sizes.

The double-stacked design provides redundancy and increased optical output in a compact footprint—critical for congested anchorages or close-quarters maneuvering where visibility is non-negotiable. The horizontal mount orientation integrates cleanly into modern hull lines without requiring complex through-hull modifications. The 2NM visibility range ensures adequate signal distance for recreational and commercial operators, meeting international maritime lighting standards. Black anodized housing resists corrosion in salt-air environments, a practical consideration for coastal and offshore vessels.

This light suits weekend cruisers, fishing boats, and professional vessels needing dependable port-side navigation lighting. Whether you're transiting narrow channels at dusk, anchoring overnight, or meeting USCG/international maritime regulations, a dedicated sidelight eliminates reliance on masthead or all-around lights. The Series 301-009 pairs seamlessly with starboard and stern fixtures in a complete Lopolight system, giving operators modular control over their vessel's lighting footprint and redundancy architecture.
