What feature should be noted for taxiway edge lights?

Taxiway edge lights are designed to provide crucial guidance to pilots operating on the taxiways of airports. The correct feature to note is that these lights are typically blue in color.

Blue lights or blue reflectors along the edges of the taxiway serve as a clear visual indication to pilots about the boundary of the taxiway, helping them navigate safely and accurately. This distinct color is standardized across many airports to ensure uniformity in visual cues, reducing the risk of confusion or errors during taxiing.

Other features, such as the use of non-illuminated markers, varying colors like red and white, or amber lights, do not represent the specific characteristics of taxiway edge lights and can lead to misunderstanding about their function and appearance. Understanding the correct identification of these lights is essential for maintaining safety in ground operations at airports.
