Sea-Dog Stainless Steel Stern Light

The Sea-Dog Stainless Steel Stern Light (MPN 400130-1) is a 135° navigation light engineered for marine vessels requiring USCG-compliant deck lighting. Constructed from stamped 304 stainless steel, this stern light delivers corrosion resistance critical in saltwater environments where standard finishes deteriorate rapidly. The unit is designed as a replacement fixture for existing marine lighting systems, not for new construction installations.

Proper installation is essential for USCG compliance. The stern light mounts using three #4 right-hand fasteners (sold separately) and must be positioned to maintain correct visual alignment and unimpeded sight lines per USCG navigation light regulations for 1 NM and 2 NM visibility distances. The compact dimensions (4 x 2 x 8 inches) and minimal weight (0.15 lbs) ensure installation flexibility across various stern-mounted configurations without adding significant structural load.

This navigation light serves operators of recreational and commercial vessels, fishing boats, and offshore platforms where federal maritime regulations mandate proper stern lighting for nighttime safety and collision avoidance. 304 stainless steel resists oxidation and pitting in corrosive salt-air conditions far longer than standard steel, reducing maintenance cycles and replacement frequency. Users upgrading aging lighting systems benefit from this fixture's rugged construction and direct replacement compatibility with standard mounting patterns.

Vessel operators should consult current USCG regulations and their vessel's electrical specifications before installation to ensure proper wattage and voltage compatibility. The 135° beam angle is standard for stern-mounted positions and provides the required aft visibility range when mounted at the correct height above the waterline.
