What color are bow lights on the port side and starboard side of a boat?

The bow lights on a boat serve a critical function in navigation and safety. The port side, which is the left side when facing forward, is indicated by a red light. This color is universally recognized in maritime navigation, helping other vessels identify the direction a boat is traveling. Conversely, the starboard side, which is the right side when facing forward, is indicated by a green light. This color combination of red on the port side and green on the starboard side helps to prevent collisions by allowing other boat operators to understand the orientation of your vessel at a distance.

This system of colored lights follows the International Regulations for Preventing Collisions at Sea (COLREGS) and is used universally, making it essential for all boaters to be familiar with these colors.
