What color of lights indicates a taxiway on an airfield?

Taxiway lights are specifically designed to guide pilots and ground vehicles along taxiways, ensuring safe navigation around the airfield. The blue lights are used exclusively for taxiways, allowing for easy identification. This distinct color helps distinguish taxiways from runways, which use different lighting colors to denote their presence and usage.

In the context of airport operations, using blue lights for taxiways aids in reducing confusion, especially in low visibility conditions or during nighttime operations. Thus, recognizing and understanding the specific purpose of blue lights is crucial for effective and safe ground navigation in an aviation environment.
