The pilot controlled runway lights at Pennridge operate reliably to microphone clicks no faster than two clicks per second. The first click starts a five second timer. When the timer starts counting down the logic circuitry will count the clicks received in five seconds.

​

Three clicks = low intensity lights

Five clicks = medium intensity lights

Seven clicks = high intensity lights

 

The lights will stay on for fifteen minutes.

Additional microphone clicks will change the intensity and reset the fifteen minute timer.
