Lopolight Series 301-001 - Starboard Sidelight - 2NM - Vertical Mount - Green - Silver Housing

The Lopolight Series 301-001 Starboard Sidelight is a compact marine navigation light engineered for recreational and commercial vessel operators who demand reliable, visible lighting in low-visibility conditions. Designed to USCG and IALA standards, this green starboard sidelight delivers a 2-nautical-mile visible range, meeting regulatory requirements for vessels under 20 meters while offering the durability needed for extended offshore and coastal operations.

The vertical mount configuration integrates cleanly with modern hull designs, while the silver anodized housing resists corrosion in salt-water environments—a critical consideration for extended marine duty. At just 0.9 lbs and measuring 4×4×4 inches, the Series 301-001 minimizes visual footprint without compromising visibility output. Lopolight's focus on precision engineering translates to consistent photometric performance across wide viewing angles, ensuring other vessels identify your starboard side even in rough seas or poor weather conditions where visibility is already compromised.

This sidelight serves captains and crew operating coastal patrol vessels, fishing boats, pleasure yachts, and commercial shipping who cannot rely on improvised lighting or non-compliant fixtures. Weekend cruisers and professional mariners alike depend on Lopolight fixtures to reduce collision risk during night transits, maintain legal compliance during port approaches, and ensure proper vessel identification under international maritime law. The green filter designation marks port-side visibility with the precision required by both recreational and professional operators.

Lopolight has built its reputation since 2004 on delivering compact, high-performance lighting solutions specifically engineered for the marine environment—not adapted from automotive or industrial sources. The Series 301-001 represents the brand's commitment to combining elegant industrial design with the durability and photometric accuracy that professional mariners and serious hobbyists expect when safety and regulatory compliance depend on it.
