What Lights are Used in Airport?


Airport apron uses flood lights

For the success of an airport apron lighting project, it is essential to choose quality LEDs, with optical systems that guarantee perfect uniformity. To maximize the light beam and reduce the number of floodlights required, ProjectLights energy- efficient LEDs for large area lighting have many optics. The perfect light distribution gives high visibility and makes it easier to see obstacles.

There are many passengers flying to their destinations during the day and night. Multiple workers perform different jobs to ensure an enjoyable trip. Airports have many responsibilities to ensure the safety and security of passengers and workers. Safety and security can be affected by lighting.

Airport lighting is complex because of the wide coverage and high requirements. There are different lighting requirements at airports. Runways, taxiways and aprons are three applications that rely on the help of lighting to make things happen.


The lighting requirements for the apron are set forth by the International Civil Aviation Organization.

  • The apron should be illuminated by at least 10 lux.
  • The areas between the aircraft stands and the apron should be illuminated by an average of 10 lux.
  • The uniformity ratio of apron lighting is 4:1.

Most of the lights at the airport are on all the time. It means a lot of energy is used to illuminate the airport. The high efficiency and energy-saving of the LEDs make them the best choice for airport lighting. They can save a lot of energy. The cost-effective is due to the long lifespan of the LEDs.

It is possible to mark and guide different parts of the airport with multiple color options. The feature of LEDs is that they have color options. It is important that the lighting for the airport is waterproof and resistant to harsh environment.

Fun fact: What is apron lighting?

Modern airports have apron lighting that is needed. The apron lighting makes it easier for pilots to maneuver their planes. Safety and speed of maneuverings were increased and the quality of maintenance was improved.

Apron lighting is used for hangar entrance aprons and hangar entrances, which may include aircraft halls, aprons, aprons, aircraft hard floor stands, sidewalks, and hangar aprons. The area of the airport where the aircraft is parked, unloaded or loaded is referred to as the hangar apron.

Airport runway use Runway End Identifier Lights (REIL)


Rapid and positive identification of the approach end of a runway is provided by REILs. There are two flashing lights on each side of the threshold.

There are red lights at the end of the runway. runway threshold end lights are a common solution at airports. The airfield light is green and red at the same time. It is green in one direction and red in another.

Marking edges, centerline, and edges of the runway is one of the ways that runway lighting can give pilots information. Various lighting patterns can be arranged in the runway lighting system and pilots can easily see the condition of the runway.

The runway has thousands of lights that illuminate it to provide a clear environment for pilots, workers, and passengers. It is possible for pilots to determine if they are on the right track to land or take off. The lights on the runway are elevated.

At the last 300m of the runway there is an instrument that tells the pilot to pay attention to the caution zone. runway lights are not allowed to protrude more than 1 cm from the road. The black hole effect happens when pilots drive on the runway.

The edge lights of the runway move far and fast in both sides of peripheral vision as pilots focus on the center line. The central area has black in it’s color due to the contrast of visual information.

Colored Lighting for Taxiway


Accidents are possible when airplanes are moved in a low speed at the taxiway because of poor visibility. Adequate lighting is needed along the taxiway. The taxiway is near the runway. Taxiway can be easily understood from the runway and apron through different lighting arrangements.

Taxiway edge lights illuminate the edges of taxiways during times of darkness or restricted visibility. The blue light comes from the fixture. At most major airports the lights have variable intensity settings that can be adjusted at pilot request.

Intersections of taxiway, taxiway-runway, and taxiway-apron are easy to identify. There is a reduction in the risk of accident when there are clear marks on the runway. The visual effects are affected by the amount of lights in the room.

The straight section needs a distance of between 6.5m to 7.5m and the curves between 2.5m to 3.5m. The location of edge lights is not as strict as a runway. It’s acceptable to have a longer distance below 80 cm. The lighting on the edge of the taxiway is blue in color while the center of the taxiway is green. The pilot needs to reach the right traffic guidance by using lights in different colors. The lights for the taxiway are not very bright.
