Indicator lights can be added to turnstiles to help aid the flow of traffic by providing a small red and green light that changes with the status of the passage. For example, when someone approaches the turnstile the indicator light will be red. When someone swipes their card and the turnstile unlocks the red light will shut off and the green light will turn on, signaling that that passage is ready to use. After they pass through and the turnstile locks back up the indicator light will turn back to red. When indicator lights are added they are factory wired and installed right above the card reader plate.
Comes with 4 indicator lights for tandem turnstiles
