Lopolight 201-004 Combined Port & Starboard Sidelight - 2NM LED Navigation Light, Silver Housing, Vertical Mount

The Lopolight 201-004 is a combined port and starboard navigation light in a single compact silver-anodized aluminum housing, designed to be mounted vertically against a flat surface such as a mast face, bulkhead, cabin side, or pilothouse front. A single high-power LED sits behind red and green PMMA (acrylic) lenses, each throwing a precise 112.5° arc so the combined unit delivers the full 225° bi-color sidelight pattern required on boats and yachts from roughly 39' to 65' (12–20m).

Built by Lopolight, a Danish manufacturer that has specialized in LED navigation lighting since 2004, this fixture is CNC-machined and fully potted with silicon-epoxy resin, making it vibration-proof, waterproof, and effectively bulb-free for the life of the unit. It runs on a wide 10–32 VDC input so it works seamlessly across 12V and 24V marine electrical systems, and it draws far less current than a traditional incandescent sidelight while meeting USCG, COLREG72, and EN14744 requirements.
