Boat owners, this Pactrade marine navigation light is built to professional standards without the professional price tag! Made from polished stainless steel 304, it's corrosion-resistant and durable enough for saltwater use. The horizontal mount design features both green starboard and red port lights in one unit, with a combined 225-degree visibility arc that meets standard navigation requirements. The LED technology is efficient and bright - with 1W for each color providing 50 lumens of output visible up to 1 nautical mile. The IP66 rating means it's completely protected against dust and powerful water jets, so you can install it with confidence in exposed locations. The working voltage range of 10-30V DC makes it compatible with most boat electrical systems. Two different mounting plates are included, giving you flexibility in how you install it based on your boat's configuration. The construction feels solid and well-made, with clean machining and proper sealing. At approximately 2.5x2 inches for the light itself, it's compact but highly visible. The CE and RoHS certifications provide that extra assurance of quality and safety standards. Whether you're replacing old navigation lights or outfitting a new boat, this light provides reliable performance that you can count on during night operations or low visibility conditions. The stainless steel housing maintains its appearance season after season, and the LED bulbs should last for thousands of hours of use. It's one of those marine accessories where the quality really shows in the details.
