Runway end lights – a pair of four lights on each side of the runway on precision instrument runways, these lights extend along the full width of the runway. These lights show green when viewed by approaching aircraft and red when seen from the runway. Runway edge lights – white elevated lights that run the length of the runway on either ...
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 majority of runway edge lights are clear or white, [2] but there are some exceptions to provide additional information to pilots in certain circumstances. When an instrument runway lighting is designed, the last 600 metres (2,000 ft), or one-half of the runway length available (whichever is less), are bi-directional.
The red lights are always on the side closest to the runway. If the PAPI is on the right-hand side of the runway (non-standard), the red lights will be on the left. At some locations, PAPIs are installed on both sides of the runway but this level of provision is beyond the requirements of the International Civil Aviation Organization (ICAO).
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.

Takeoff Hold Lights (THL): Red unidirectional lights in a double-longitudinal row, located parallel to runway centerline lighting. Runway Intersection Lights (RIL): Similar to THLs, but located on a runway, prior to intersection with another runway. On taxiways, Runway Entrance Lights (RELs) show that runways are not safe to enter or cross. On ...
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.
