What color lights are associated with taxiway edge lights?

Taxiway edge lights are specifically designed to help pilots identify the boundaries of taxiways. These lights are colored blue and are aimed at clearly marking the taxiway edges, ensuring safe navigation on the airfield during both day and night operations. The use of blue lights is standard in aviation lighting systems and plays a crucial role in providing visibility and guidance to vehicles and aircraft operating on the ground.

Understanding the function of these lights is vital for maintaining safety in high-traffic areas such as airports. The other colors listed do not indicate taxiway edges. White lights are typically used for runway edge lights, red lights signal the end of a runway or indicate a construction area, and yellow lights are often used for certain types of cautionary signage or guidance, but not for taxiway edges. The blue lights are key to defining the safe operational area for ground movements, making them essential for pilots and vehicle operators alike.
