Lopolight Series 301-002 - Port Sidelight - 2NM - Vertical Mount - Red - Black Housing

The Lopolight Series 301-002 Port Sidelight is a professional-grade navigation light engineered for serious boaters and commercial mariners who demand reliability in low-visibility conditions. This red port sidelight meets international maritime regulations and provides the 2-nautical-mile visibility range required for proper vessel identification during dawn, dusk, and nighttime operation.

Built with a durable black housing and designed for vertical mounting, the Series 301-002 combines efficient LED technology with robust marine-grade construction to withstand saltwater exposure and harsh weather. The compact 4 x 4 x 5 inch profile fits cleanly on cabin tops, railings, or mast installations without creating obstruction or excessive weight.

This sidelight performs equally well on displacement cruisers, center consoles, trawlers, and commercial fishing vessels operating in U.S. waters and international routes. The red lens cuts through ambient light and provides the distinct port-side indication required by the International Regulations for Preventing Collisions at Sea (COLREGS), ensuring other vessels instantly recognize your heading and position.
