The aircraft's external lights are divided into two categories, the first used to help pilots to see, and others that make aircraft visible to others. Commercial aircraft are equipped with a variety of lights used for navigation and safety purposes and improved visibility during flight or on airport grounds. The aircraft is powerful during the dark and bad weather conditions to help the crew see in front of them. These super bright lights are used as aircraft move in the airport and during takeoff and landing.

Other lights are also used to detect ice on motors and wings, and these lights are also effective to avoid collisions. The lights that help make a plane visible to others are rooted in ancient navy ships. The red light on the left side and green on the right side Along with white and red flashing lights in the wings, and the flap of the aircraft, all of which help determine the location and direction of the aircraft.

There are also bright white lights on the landing systems in most aircraft. This light is usually operated when the aircraft is in motion on the ground. After the aircraft stops and the motors are turned off, the anti-collision lights are turned off. This signal to ground personnel that they can approach safely Of the aircraft at this stage.

Modern models of lamps and outdoor lighting systems manufactured by specialized companies take into account the power of clouds during flight, and are easily controlled by pilots. Aircraft also have lighting systems for the airline's logo and brand, and lights are provided in some aircraft primarily to help technicians on the ground There are a total of 23 external lights on the single-aisle Airbus A320 and 41 light on the A350 XWB.

The lighting systems also help pilots see other aircraft flying in the air of busy cities and airports until they get permission to land. White lights at the rear help to determine the direction of the aircraft left and right or move away. There are also red lights to prevent collisions at the top Plane and bottom so that this light can be seen from different angles, and is usually stopped after running the engines and ready to take off.

During the gradual rise of the departure of the aircraft, the navigation lights for landing and take off, along with the wing lights and logo, up to 18 thousand feet to increase visibility in the crowded airspace, and the same process is repeated during the phase of gradual decline.
