What are Runway Threshold Identification Lights used for?

Runway Threshold Identification Lights are specifically designed to indicate the approach end of a runway. These lights are crucial for pilots as they help define the actual beginning of the runway where landing should occur. The lights are typically installed at the threshold of the runway and are especially useful during low visibility conditions, enhancing the visual cues available to pilots as they approach for landing.

This clear visual indication is vital for ensuring that pilots can accurately identify where the runway starts, which is essential for safe and proper landings. In conditions where natural lighting may not provide sufficient visibility, these lights serve as an important navigational aid to prevent mishaps associated with misjudging the runway's location. Consequently, they are a critical component of a runway's safety features.
