12.7.2 Pilots may request that lights be turned on or off. Runway edge lights, in.pavement lights and approach lights also have intensity controls which may be varied to meet the pilot’s request. Sequenced flashing lights may be turned on and off. Some sequenced flashing system also have intensity control.
12.8 Pilot Control of Airport Lighting
12.8.1 Radio control of lighting is available at selected airports to provide airborne control of lights by keying the aircraft’s microphone. Control of lighting system is often available at locations without specified hours for lighting or where there is no control tower or FSS, or when the control tower or FSS is closed (locations with a part.time tower or FSS). All lighting systems which are radio controlled at an airport, whether on a single runway or multiple runways, operate on the same radio frequency. (See TBL AD 1.1.2 and TBL AD 1.1.3.)
12.8.2 With FAA approved systems, various com-binations of medium intensity approach lights, runway lights, taxiways lights, VASI and/or REIL may be activated by radio control. On runways with both approach lighting and runway lighting (runway edge lights, taxiway lights, etc.) systems, the approach lighting system takes precedence for air.to.groundradio control over the runway lighting system which is set at a predetermined intensity step, based on expected visibility conditions. Runways without approach lighting may provide radio controlled intensity adjustments of runway edge lights. Other lighting systems, including VASI, REIL, and taxiway lights, may be either controlled with the runway edge lights or controlled independently of the runway edge lights.
12.8.3 The control system consists of a 3.step control responsive to 7, 5, and/or 3 microphone clicks. This 3.step control will turn on lighting facilities capable of either 3.step, 2.step or 1.step

(except for 1.step and 2.step REILs which may be All lighting is illuminated for a period of 15 minutes turned off when desired by keying the mike 5 or from the most recent time of activation and may not 3 times, respectively).

12.8.4 Suggested use is to always initially key the mike 7 times; this assures that all controlled lights are turned on to the maximum available intensity. If desired, adjustment can then be made, where the capability is provided, to a lower intensity (or the REIL turned off) by keying 5 and/or 3 times. Due to the close proximity of airports using the same frequency, radio controlled lighting receivers may be set at a low sensitivity requiring the aircraft to be relatively close to activate the system. Consequently, even when lights are on, always key mike as directed when overflying an airport of intended landing or just prior to entering the final segment of an approach. This will assure the aircraft is close enough to activate the system and a full 15 minutes lighting duration is available. Approved lighting systems may be activated by keying the mike (within 5 seconds) as indicated in TBL AD 1.1.4.
