What is the purpose of the green and red navigation lights on the boat?

The purpose of the green and red navigation lights on a boat is to indicate the direction of travel. These lights help other vessels determine the orientation and heading of your boat, especially during nighttime or low visibility conditions. The green light is typically placed on the starboard (right) side of the boat, while the red light is located on the port (left) side. When these lights are visible, they provide crucial information about whether the boat is moving towards or away from another vessel. This system is part of standardized maritime navigation regulations to enhance safety and prevent collisions on the water.

The other options may refer to different signaling or lighting systems, but they do not accurately describe the primary function of the green and red navigation lights.
