What are the white red and green lights to a boat?

The white, red, and green lights on a boat are part of its navigation lighting system. The red light is displayed on the port side (left) of the boat, while the green light is on the starboard side (right). The white light, often positioned at the stern or as a masthead light, serves to indicate the boat's presence and direction to other vessels. Together, these lights help in determining a boat's orientation and movement at night or in low visibility conditions.
