Navigation Lights are special lights required on all ships and boats that show their position and movement to other vessels at night or in poor visibility. These lights are like traffic signals for the sea - they help prevent collisions by telling other boats which direction a vessel is moving, whether it's anchored, and how big it is. Different colored lights (red, green, and white) placed in specific positions on the vessel have different meanings, similar to how traffic lights work on roads. This is a fundamental safety system that every maritime professional needs to understand.
