Why: Pilot-controlled lighting responds to 7, 5 or 3 mic clicks. The AIM suggests starting with 7 clicks in 5 seconds for the highest available intensity, then using 5 or 3 clicks to dim compatible systems.

Huh, didn't know that: The lights stay on for 15 minutes from the most recent activation, so key the mic again as you near the airport.
