Attwood presents the most energy efficient LED navigational lights in the world. Good to up to one nautical mile. Through the use of proprietary optical design techniques, we've optimized our lens design to harness nearly 90% of all light being generated by the LED. In doing so, our line of 3500 and 5500 series navigational lights exceed US Coast Guard requirements with the fewest and lowest watt LEDs of any navigational light manufactured today. Less energy used by navigational lighting means more energy available for powering your boat and enjoying time on the water.

• Designed to resist corrosion in even the most extreme saltwater environments
• Lights are completely sealed and watertight
• LED technology keeps lights cool to the touch
• Rated for 50,000+ hours of use
• Built-in "Tell Tale" indicators
