How are touchdown zone lights arranged?

Two rows of light bars with 3 unidirectional lights each, facing the threshold; start 100 feet from the threshold and continue to 3,000 feet down the runway or one-half the runway length for runways < 6,000 ft

Touchdown zone lighting is designed to give pilots a clear visual cue of the landing zone just beyond the threshold. It uses two parallel rows of light bars facing toward the runway, with three unidirectional lights in each row. These lights begin 100 feet from the threshold and extend to 3,000 feet down the runway, or up to half the runway length if the runway is shorter than 6,000 feet. This arrangement provides a symmetric, well-lit zone that helps with depth perception and locating the proper touchdown area.
