What kind of lights do taxiways use at night?

Taxiways utilize blue edge lights at night to guide aircraft safely along the ground. These blue lights are specifically designed to delineate the boundaries of taxiways and ensure that pilots can navigate accurately during nighttime operations or low-visibility conditions. The use of blue lights is standardized across airports, providing a consistent and recognizable visual cue for pilots.

Green lights are typically used for runway thresholds, while red lights are often associated with indicating areas that should not be entered, such as the edges of runways. Amber lights can signal caution or warning in various contexts, but they are not the standard for taxiway edges. Thus, blue lights serve a critical function in maintaining safety and efficiency in airfield operations.
