Sea-Dog Stainless Steel Round Transom Light

The Sea-Dog Stainless Steel Round Transom Light (MPN 400135-1) is a USCG-approved navigation light designed for vessel owners and marine operators who require reliable, corrosion-resistant deck and transom illumination. This replacement light serves as a critical safety component for watercraft, enabling proper night navigation and regulatory compliance in both coastal and offshore environments. Built to withstand harsh marine conditions, the transom light delivers consistent visibility while maintaining the durability standards expected in professional maritime and tactical applications.

Constructed from stamped 304 stainless steel, this round transom light resists saltwater corrosion and UV degradation—critical factors in extended marine deployments. The robust steel construction ensures the housing maintains structural integrity under vibration, impact, and temperature fluctuation inherent to vessel operations. Installation requires two #8 FH (flat-head) fasteners (sold separately), allowing straightforward retrofit capability for existing lighting replacements without full rewiring. The compact 5 x 2 x 7-inch footprint and lightweight 0.25 lbs design minimize weight penalty while maximizing mounting flexibility on transom surfaces and secondary deck positions.

Law enforcement marine units, tactical response teams, and professional mariners benefit from this light's proven reliability and USCG approval status. The transom light is ideal for retrofit applications where existing fixtures require replacement due to damage, wear, or operational upgrade. Compatibility with standard fastener patterns and universal mounting holes ensures installation across most vessel types and after-market deck configurations. This product is not intended for new construction projects but serves as the industry-standard replacement solution for vessels operating in high-visibility or mission-critical environments.
