Runway edge lighting are used to outline the edges of runways during periods of darkness or restricted visibility conditions. These light systems are classified according to the intensity they are capable of producing: Many HIRL and MIRL systems have variable intensity controls, whereas the LIRLs normally have one intensity setting. At airports ...
Approach lights at Jyväskylä Airport, Finland The approach lighting system of Bremen Airport Approach lighting at Love Field, Dallas. An approach lighting system (ALS) is a lighting system installed on the approach end of an airport runway and consisting of a series of lightbars, strobe lights, or a combination of the two that extends outward from the runway end.

The visual approach slope indicator (VASI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. These lights may be visible from up to 8 kilometres (5.0 mi) during the day and up to 32 kilometres (20 mi) or more at night.
The aircraft is slightly below the glideslope. A precision approach path indicator ( PAPI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. It is generally located on the left-hand side of the runway approximately 300 meters beyond the landing threshold of ...
Runway end identifier lights ( REIL [1]) (ICAO identifies these as Runway Threshold Identification Lights) are installed at many airports to provide rapid and positive identification of the approach end of a particular runway. The system consists of a pair of synchronized flashing lights located laterally on each side of the runway threshold.
Visual Glide Slope Indicator. Visual Glide Slope Indicator or Visual Glideslope Indicator (VGSI) is a ground device that uses lights to assist a pilot in landing an airplane at an airport. The lights define a vertical approach path during the final approach to a runway and can help the pilot determine if the airplane is too high or too low for ...
These lights can be closer together at taxiway intersections. Taxiway Centerline Lights: They are steady burning and emit green light located along the taxiway centerline. Where a taxiway crosses a runway, or where a "lead-off" taxiway centreline leads off of a runway to join a taxiway, these lights will alternate yellow and green. Taxiway ...
Aviation light signals. A United States Air Force airman with a signal light gun that can be used to control aircraft with radio failure. In the case of a radio failure or aircraft not equipped with a radio, or in the case of a deaf pilot, air traffic control may use a signal lamp (called a "signal light gun" or "light gun" by the FAA [ 1 ][ 2 ...
