What color lights are used to identify taxiway edges?

Taxiway edge lights serve a critical function in guiding aircraft along taxiways, particularly during low visibility conditions. The correct color for taxiway edge lights is blue. This color is universally recognized as indicating the boundaries of taxiways, providing clear visual guidance to pilots as they maneuver on the ground.

Blue lights enhance safety by clearly marking the edges of the taxiway, reducing the risk of aircraft straying off course or onto adjoining areas such as runways or service roads. The use of blue lights specifically for taxiways is standard across airfields to ensure consistency and identification, allowing pilots to quickly orient themselves.

In contrast, other colors have specific meanings in aviation lighting. For instance, red lights are often used to indicate hazards or stop areas, while green lights are typically associated with runway centerlines. White lights can also be used for runway edge markings. Understanding this color coding is crucial for safe airfield operations, which is why it’s essential to recognize that blue is the designated color for taxiway edge lights.
