navigation lights

Navigation lights are specialized signals on boats and ships used to indicate their position, direction, and movement to other vessels, especially at night or in poor visibility. They typically include red and green sidelights, a white stern (rear) light, and a white masthead or forward light to show if a vessel is moving or anchored. These lights help prevent collisions by communicating a vessel’s orientation and status, enabling mariners to navigate safely and follow maritime regulations. Proper use of navigation lights is essential for safe and efficient maritime traffic management.
