The Attwood 6556-7 is a USCG-compliant LED transom navigation light rated to 3 nautical miles — one of the first LED sternlights to meet that standard. Proprietary optics concentrate 135 degrees of white light aft while keeping the helm in a natural shadow. The electropolished stainless steel cover resists corrosion, and a snap-in surface-mount design eliminates exposed fasteners for a clean installation on any transom that accepts Attwood or Perko mounting patterns. At just 1.5 watts, it draws minimal current from a 12V system and is rated for 50,000+ hours of service.
