What color is the starboard light on a vessel?

The starboard light on a vessel is green. This is a standardized signaling system utilized in maritime navigation. The purpose of the starboard light is to indicate the right side of the vessel when facing forward. The use of distinct colors for navigational lights helps with visibility and identification of the vessel's orientation and direction, especially during night or low-visibility conditions.

In marine navigation, the combination of port and starboard lights (red for port and green for starboard) serves to help other vessels determine the position and heading of a vessel. Knowing the color of the starboard light is essential for safe navigation and avoiding collisions on the water.
