Alright boaters, this Navilight tricolor navigation light is seriously handy for smaller vessels or as a backup light. It's US Coast Guard approved for 2 nautical miles visibility, which covers boats up to 39 feet traveling over 7 knots - so perfect for most recreational boats, kayaks, or dinghies. The five operating modes are super versatile: full tricolor masthead light (red, green, and white sectors), bicolor sidelight (red and green together), individual red sidelight, individual green sidelight, and white sternlight. The magnetic base is genius - it attaches securely to metal surfaces but also comes with a mounting screw, lanyard, and Velcro strap for multiple mounting options. It's waterproof and submersible to 20 meters (66 feet), and it actually floats light-side-up if it accidentally goes overboard. The 360-degree light coverage with clearly defined color zones ensures you're visible from all directions. It runs on three AAA batteries (not included), making it portable and easy to power. The compact size means it stores easily in your gear bag or even a pocket. Whether you need temporary navigation lights, a backup system, or primary lights for a small boat, this delivers reliable performance in a convenient package. The build quality feels solid - not some cheap plastic toy but actual marine-grade equipment. For the price, having USCG-approved navigation lighting that's this versatile and portable is seriously good value for any boater's safety kit.
