Lopolight Series 301-008 - Starboard Sidelight - 2NM - Horizontal Mount - Green - Black Housing

The Lopolight Series 301-008 Starboard Sidelight is a compact, horizontally-mounted green navigation light engineered for reliable nighttime vessel identification across 2 nautical miles. Built by Lopolight—a manufacturer specializing in marine navigation lighting for boats and yachts since 2004—this starboard sidelight delivers the precise, regulation-compliant visibility required by International Regulations for Preventing Collisions at Sea (COLREGS) without excessive power draw or bulky mounting hardware.

The 2-nautical-mile visibility range is the standard minimum for vessels under 50 meters, making this light suitable for fishing boats, center consoles, and mid-sized cruisers operating in coastal and offshore waters. The green lens identifies the starboard (right) side of your vessel, and the compact black housing integrates cleanly into modern hull designs without protruding hardware that catches spray or reduces hydrodynamic efficiency. Horizontal mounting allows flexible installation on railings, pulpits, or cabin hardtops, accommodating the layout constraints typical of production and custom vessels.

This light suits weekend fishermen installing a basic navigation lighting system as well as serious offshore anglers upgrading existing sidelights to a more compact, efficient solution. Lopolight's range covers single and paired light configurations, so a complete port-starboard setup requires pairing this starboard unit with a port (red) sidelight of equivalent specifications. At 1.4 pounds and measuring 4 by 4 by 5 inches, the 301-008 occupies minimal deck space while meeting COLREGS photometric and color requirements for safe nighttime operation.
