Lopolight Combined Sidelight 1NM Silver Housing w/FB Base 101-003-FB

Lopolight's Combined Sidelight (101-003-FB) is a horizontally-mounted, 1-nautical-mile port/starboard navigation light built for leisure vessels under 12 meters (39.4'). Housed in a precision-machined, silver anodized aluminum enclosure with side-by-side red and green PMMA lenses, it delivers COLREG-compliant navigation lighting in a compact, low-profile package. The FB (flat base) design centers the wiring for antenna-style pole mounting, offering both a screw-down deck installation and a from-below mounting option for a cleaner, sleeker finished look.

Built to Lopolight's signature standard, this light uses long-life LEDs backed by a fully potted, waterproof interior rated to IP68, making it vibration-proof and submersible. It runs on a wide 10-32VDC input, so it works seamlessly on both 12V and 24V boat electrical systems, and comes complete with a 2.5m (8.2') integrated cable for straightforward wiring. It carries certification to COLREG72, EN14744, IEC 60945, IACS E10, USCG, ABS, M.E.D., DNV, and LR standards, making it suitable for a wide range of recreational and light commercial vessels.
