Stop Bar Configuration
A stop bar consists of a row of L-852S unidirectional in-pavement red lights that prohibits access to an active runway or taxiway. An elevated red light, L-862S, is set on each side of the taxiway at runway intersections. Stop bars are for low visibility operations.
Guard Light Configuration
Runway guard lights, L-852G, are alternating yellow in-pavement lights that may be individually controlled and monitored to provide for all-weather operation protection against runway incursions.
