The Stern Navigation Signal Light with white/yellow options and a power rating of 2*60W/2*65W is a critical component for maritime safety. These lights are designed to ensure visibility of vessels in low-light conditions and to communicate the vessel's position and status to other nearby ships, helping to prevent collisions. The dual power options allow for flexibility depending on the vessel's power capabilities and the environmental conditions. Proper installation and maintenance of these lights are essential for compliance with international maritime regulations.
