The RWSL system presently consists of two configurations pictured in the diagrams below: Runway Entrance Lights (RELs) are installed at taxiways and Takeoff Hold Lights (THLs) are on runways.
RWSL operates by automatically illuminating red lights if the airfield's Airport Surface Detection Equipment, Model X (ASDE-X) detects traffic on or approaching the same runway.
RWSL is comprised of two types of red warning lights embedded in the pavement of a runway or taxiway: Runway Entrance Lights (REL), visible from the taxi hold position, that turn on automatically when it is unsafe to enter a runway; and Takeoff Hold Lights (THL), visible from the takeoff hold point, that illuminate automatically when it is unsafe to depart from a runway.
RWSL is a system of red lights embedded in runways that are triggered automatically by ASDE-X surveillance radar to warn pilots if it is unsafe to cross or enter a runway.
Illuminated RWSLs mean aircraft should stop and inform ATC.
