Which of the following statements is true about taxiway lighting?

Taxiway lighting plays a crucial role in supporting aircraft during ground operations, particularly at night or in low-visibility conditions. These lights are designed to provide guidance and enhance safety as pilots navigate taxiways to and from runways and other areas of the airport. By improving visibility, taxiway lights help prevent accidents and ensure that aircraft can move safely and efficiently on the ground.

The other statements do not accurately reflect the characteristics or purposes of taxiway lighting. For instance, taxiway lights are not limited to rural airports; they are found at airports of all sizes, including major international hubs. Additionally, while many taxiway lights are yellow to indicate taxiway edges, they are not solely yellow; some lights can be blue or green, depending on their specific function. Furthermore, taxiway lights are not exclusively located at the centerline; they may be installed along the edges as well, further enhancing visibility and guidance for taxiing aircraft.
