The RAILBLAZA Illuminate Navigational Bow Light outshines all others! This navigational light meets the required standards for a port/starboard navigation light for power and sailboats under 36 feet. This light is great for use where cables can’t be run. RAILBLAZA has made a port/starboard light, and not a tri-color for a very good reason, as their target market for this product is power boats under 36 feet in length. Like all RAILBLAZA products, this light has been designed and tested in harsh sunlight and saltwater environments meaning it will give many years of fault free service. To maximize battery life, RAILBLAZA has used high-quality Osram power LEDs, and a high-efficiency digital circuit. It is lightweight and IP67 rated for protection against dust and water. These features mean it will float with the lens up and out of the water. With the light being battery powered, it’s very simple to install with no external wiring.
