Lopolght Series 201-004 - Starboard & Port Sidelight - 2NM - Vertical Mount - Green/Red - Silver Housing

The Lopolight Series 201-004 Starboard & Port Sidelight is a dual-purpose navigation light designed for vessels requiring combined red and green sidelighting in a single compact fixture. This 2NM (two nautical mile) visibility light meets COLREGS (International Regulations for Preventing Collisions at Sea) requirements and delivers reliable performance across a range of vessel sizes, from center console fishing boats to cruising sailboats and small commercial craft. The vertical mount configuration and silver housing provide a clean aesthetic while withstanding the corrosive marine environment.

Built by Lopolight—a company with nearly two decades of marine lighting innovation—this sidelight combines compact dimensions (4 x 4 x 5 inches) with efficient LED technology that reduces power draw compared to traditional incandescent navigation lights. The 2NM range is suitable for vessels under 50 meters and provides the visibility distance required by international maritime law for proper collision avoidance. The green/red dual-color design consolidates port and starboard functionality into a single installation point, simplifying wiring and reducing clutter on the mast or cabin top. At 1.05 lbs, the fixture imposes minimal structural load, making it ideal for retrofit installations on boats where weight distribution matters.

This light is built for weekend fishermen who want straightforward, code-compliant navigation lighting without complexity, and for serious offshore anglers who demand reliability in salt-air environments. The vertical mounting style works well on center console towers, hardtops, and cabin cruisers where deck space is limited. Boaters upgrading from older incandescent units will appreciate the reduced electrical demand, longer service life, and maintenance-free operation that LED navigation lights provide. The Lopolight 201-004 addresses the practical need for a compact, durable sidelight that meets safety regulations while occupying minimal real estate on modern vessels.
