Why are NAV lights red and green?
Navigation lights, also known as running lights, are one of the most important safety features for both commercial and recreational vessels. They are required by law to be installed on all boats that are used for navigation in the water. The purpose of these lights is to indicate the direction and position of the vessel to other boats and provide information on the vessel’s course of movement.
The use of red and green for navigation lights dates back to the earliest days of maritime history. It was first adopted by the British Navy in the 19th century and was later adopted as the international standard. The reason for the use of red and green colors is due to the way our eyes perceive colors in different light levels.
At nighttime, our eyes are more sensitive to the green color spectrum, while during the daytime, our eyes are more sensitive to the red color spectrum.
The red light is placed on the port side (left-hand side of the vessel when facing forward), while the green light is placed on the starboard side (right-hand side of the vessel when facing forward). This configuration allows other boats to determine the direction of the vessel based on the color they see.
If a navigator sees a red light, they know that the vessel is traveling towards their right side or starboard. Conversely, if they see a green light, they know that the vessel is traveling towards their left side or port.
Additionally, navigation lights use these two colors to indicate different aspects of the vessel’s course. For example, an all-around white light indicates that the vessel is anchored, while a flashing red light indicates that the vessel is not under command, and a flashing green light indicates a pilot vessel.
Furthermore, the positions of the navigation lights signal the size and shape of the vessel, which is crucial information for determining the vessel’s course of movement.
The use of red and green for navigation lights is based on the way our eyes perceive color at night and daytime. It is an international standard that provides vital information about a vessel’s course of movement and position to ensure the safe passage of all vessels at sea.
