Navigation lights are essential devices used in transportation to signal the position, orientation, and movement of vehicles and vessels. Specifically designed for navigation purposes, these lights are fitted on aircraft, ships, and watercraft to provide visibility and awareness at sea or in the air. The primary purpose of navigation lights is to ensure the safety of navigation by aiding in the identification, communication, and avoidance of collisions with other vessels or aircraft.
Typically equipped with colored lenses, navigation lights emit distinctive light signals that convey specific information to other operators and observers. On aircraft, navigation lights are typically located on the wings and tail, with the left wingtip light being green, the right wingtip light being red, and the tail light either white or red. This configuration allows pilots to quickly determine the relative position and direction of nearby aircraft during nighttime or low visibility conditions.
On ships and watercraft, navigation lights are designed to fulfill similar roles. Commonly found on the bow, stern, and masthead, these lights are also color-coded to provide specific indications. The port (left) side light is red, the starboard (right) side light is green, and the stern (rear) light is white. Additionally, larger vessels often feature a masthead light, which is white and positioned higher up on the vessel to further aid in visibility.
To summarize, navigation lights are essential lighting devices used in transportation to facilitate safe navigation, prevent collisions, and convey information about a vessel or aircraft's position, direction, and status.
