What is the standard light color for the left wingtip of an aircraft?

The standard light color for the left wingtip of an aircraft is red. This is a universally accepted convention that helps with identifying the orientation and direction of aircraft in flight. The red light on the left wingtip assists pilots in determining the relative position and direction of other aircraft, especially at night or in low-visibility conditions.

According to the regulations outlined by the International Civil Aviation Organization (ICAO), aircraft are required to have specific navigation lights: a red light on the left wingtip, a green light on the right wingtip, and a white light on the tail. This system is crucial for maintaining safety in the airspace, as it allows pilots to quickly discern the flight paths of nearby aircraft during takeoffs, landings, and when operating in close proximity to others.
