Types of aircraft lights
The aircraft lighting system encompasses the elements necessary for pilots to see from their aircraft seat. It also allows anyone on the ground to be able to see the plane from a distance. Finally, it also brings together the lights in the passenger cabin and aircraft compartments.
For a better understanding of the aircraft lighting system, we will divide the aircraft lights into exterior and interior.
Aircraft lights located on the outside
The aircraft’s exterior lights form a high-intensity light pattern. This mainly allows to illuminate take-off and landing runways. The exterior lights of the plane allow to see from inside the plane and that from the outside the plane can be easily located.
Taxi or taxi lights
They illuminate the forward area of the aircraft and are used when the aircraft is moved from the parking lot to the head of the airport runway. They are installed in the nose landing gear of the aircraft. Although many of them are already LED technology, there are also filament ones.
In this case, they usually have a power of 250 watts fed. In addition, they usually have an automatic shutdown system that prevents them from staying on when the landing gear is retracted.
takeoff and landing lights
They illuminate the airport runway and are lights of approximately 600 watts of power. However, the trend is to install LED lights with lower power and equal brightness.
Boeing 737 airplane landing lights
Depending on the aircraft model, the takeoff lights can be found installed on the same bulb as the taxi light. If it is part of the same bulb, there will be a specific LED filament or lights for each light.
The place of installation of these lights depends on each manufacturer, but in general they are usually installed on the wing of the aircraft.
The electric motor that extends the headlamp is powerful enough to extend the headlamp in flight. However, a single extended headlight penalizes an aircraft’s fuel consumption by at least 1% per hour of flight.

They illuminate the lateral areas of the aircraft to facilitate vision in turns. They can be located on the landing gear or on the fuselage of the aircraft. Installed in the fuselage, they also illuminate the work areas of the aircraft. Being auxiliary lights, the power is intermediate, approximately 200 watts of power.
Aircraft wings and engine lighting lights
airplane tail lights
They are used lamps located in the horizontal stabilizer of the plane to illuminate the company logo. They tend to light up near land and on approach.
aircraft navigation lights
They allow the position and direction of movement of the plane to be known from a distance. They are used both on the ground and in flight. They are composed of 3 different types of lights:
- Red, always installed on the left side of the plane
- Green, always installed on the right side of the plane
- White, installed on the wing tips, tail cone or horizontal stabilizer.
Wiring diagram for aircraft navigation lights
The strobe effect refers to flashing lights. They can be of two different colors:
- White: These are the brightest lights on the plane. They indicate that the plane is going to enter an airport runway or to show the position of the plane in the sky. They are installed on the tips of the wings and in the tail cone of the aircraft.
- Rojas: the purpose is to notify the ground staff that an aircraft engine is going to start, stop or is running.
Aircraft lights located inside
The interior lights of the aircraft correspond to the set of lights used mainly for lighting.
The cabin lighting is made up of a series of elements that illuminate various areas. Among these elements, the lighting of panels, maps, passenger compartment, etc. stand out.
passenger cabin lights
These lights allow passengers to have the necessary lighting during the flight. The passenger cabin lights are located on the ceiling and sides and are usually LED technology tubes or old fluorescent tubes.
Other lights available to passengers and that can be used at any time are those located in the lower part of the luggage compartments. Here are the reading lights, crew warning buttons, air vents and no-smoking signs. Next to the latter is the notice of the obligation to fasten the security centurion of the airplane seat.
airplane bathroom lights
The bathroom lights facilitate its use by passengers. They consist of LED and incandescent lights. You can also find other types of lights whose mission is to sterilize the bathroom after each use.
