Airplane Lights: Red, Green, Strobe, and Beacon

Airplane lights help pilots see, help other people see the airplane, and communicate basic information about aircraft position or operation. Some lights are required for certain operations. Others are installed for visibility, inspection, recognition, or airline branding.

If you are a student pilot, you do not need to memorize every lighting system on every airplane. You should understand the lights on your training aircraft, when to use them, and what other aircraft lights can tell you at night.

Navigation Lights

Navigation lights, also called position lights, show the aircraft's orientation. The left wingtip has a red light, the right wingtip has a green light, and the tail normally has a white light visible from behind.

These colors help you determine another aircraft's direction of travel. If you see red and green together, the aircraft may be pointed generally toward you. If you see only a white light, you may be looking at the aircraft from behind. If you see only red or only green, you are likely seeing one side of the aircraft.

Position lights are required from sunset to sunrise. Many pilots also leave them on during the day to improve visibility.

Beacon Lights

The beacon is a red anti-collision light, often located on the top or bottom of the fuselage. On older aircraft it may rotate; on newer aircraft it may flash electronically.

A common operating habit is to turn the beacon on before engine start and leave it on while the engine is running. On the ramp, a flashing beacon is a warning: stay clear, because the aircraft may be starting, running, or about to move.

Different checklists use different language, so follow the procedure for the aircraft you are flying.

Strobe Lights

Strobes are bright white anti-collision lights, often on the wingtips. They make the aircraft easier to see in flight and on or near runways.

Because strobes are intense, they can be distracting or blinding on the ground at night, especially near other aircraft. Many pilots avoid using strobes while taxiing in close quarters and turn them on before entering the runway. Again, use the aircraft checklist and local procedures.

Strobes are not a substitute for looking outside. They help, but pilots still need disciplined scanning and radio awareness.

Landing Lights

Landing lights are powerful forward-facing lights used to illuminate the runway during takeoff and landing. They also make the aircraft more visible to other traffic.

Some pilots use landing lights during the day in busy traffic areas for recognition. In many training airplanes, the landing light is on the wing or nose. In larger aircraft, landing lights may be mounted in multiple locations and may retract or pulse depending on the system.

Landing lights can burn out, so a failed light should be handled according to the regulations, equipment list, and aircraft documents that apply to the operation.

Taxi Lights

Taxi lights are aimed to help pilots see taxiways, signs, and pavement edges at night. They are usually less intense or aimed differently than landing lights.

On some aircraft, a landing light may also serve as a taxi or recognition light. On others, taxi and landing lights are separate. Know the switch layout before night operations so you are not hunting for lights while moving.

Recognition, Runway Turnoff, and Wing Inspection Lights

Recognition lights make the airplane easier to see, especially in traffic. Some systems pulse or alternate lights to attract attention.

Runway turnoff lights are angled to illuminate taxiway exits and tight turns. They are more common on larger aircraft but may appear on some smaller aircraft.

Wing inspection lights illuminate the wing leading edge, often to help detect ice at night. If your aircraft is approved for flight into known icing, the lighting and inspection procedures will be more specific. Most basic trainers are not approved for that kind of operation, but the concept is still useful to understand.

Logo and Formation Lights

Logo lights illuminate an airline tail or vertical stabilizer. They help with identification and visibility but are not usually a major concern for small-airplane training.

Formation lights are used on some military aircraft to help pilots maintain position while flying formation. Some may be designed for night-vision equipment. They are outside the normal private pilot training world, but they explain why not all aircraft lights look familiar.

What Lights Tell You at Night

At night, aircraft lights become part of your traffic scan. Red, green, and white position lights help show direction. Strobes and beacons help draw attention. Landing lights may make an aircraft appear closer or brighter than expected.

Be careful with visual illusions. A bright landing light on a dark night can appear stationary even when an aircraft is moving toward you. Use position changes, radio calls, ADS-B if available, and ATC services when appropriate.

What to Know for Your Airplane

Before solo night flying, know every exterior light switch in your aircraft. Know which lights are required, which are optional, and what your checklist says for engine start, taxi, runway entry, takeoff, cruise, landing, and shutdown.

Airplane lights are simple on the surface, but they support collision avoidance, ground safety, and night operations. Treat them as part of your normal cockpit discipline, not as decorative switches.
