What color are TWY center lights?

Taxiway (TWY) center lights are colored yellow. This yellow coloring is specifically utilized to mark the centerline of taxiways at airports, providing essential visual guidance for pilots while taxiing. The yellow lights help distinguish taxiways from runways, contributing to safer aircraft movements on the ground, especially during low visibility conditions or nighttime operations.

In contrast, runway centerline lights are typically white, which further differentiates them from taxiway markings. Understanding these distinctions is crucial for pilots and ground crew at airports, as it enhances safety and operational efficiency.
