Navigation lights are essential for boating safety, ensuring visibility and compliance with maritime regulations, especially at night or in low-visibility conditions. These lights help identify a vessel’s size, direction, and activity to other boats, preventing collisions. The primary types of navigation lights include red (port) and green (starboard) sidelights, a white stern light, and a masthead light for power-driven vessels. Sailboats, anchored boats, and larger ships may require additional lights, such as an all-around white anchor light or tri-color lights for sailing vessels. Marine navigation lights must be waterproof, corrosion-resistant, and meet international standards such as COLREGs. Regular checks and maintenance, including replacing bulbs or ensuring proper wiring, help maintain their effectiveness and reliability.
