Strobe (White Anti-Collison) LightsThese lights are only used during flight and on the runway, as they are too bright for use on the ground, particularly at night. LED lights are commonly used for strobe lights, particularly on newer aircraft.

Strobe lights.All modern aircraft also have white flashing strobe lights on the rear wingtips. These are the flashing white lights you see if you look at aircraft in the night sky. These are for collision avoidance, simply to make the aircraft more visible.
The true answer is that pilots don't see much when flying at night. For the human eye to perceive things, it needs light and something for that light to reflect off. Obviously, the one thing pilots don't want to see is something in front of them. The aircraft lights aren't actually much use either.
The spraying of airplanes as they land is a tradition known as the “water salute.” As explained by Wikipedia, it's performed for ceremonial purposes, such as the retirement of an airplane. When an airplane makes its final flight, it's honored with the water salute once it lands on the tarmac.
Though aircraft do not have headlights in the traditional sense, they do have a plethora of illuminations, each performing a different function. The lights closest to those we might have on our cars or motorbikes are the landing lights employed by the flight deck on approach to an airport.
How do pilots see at night if airplanes don t have front lights? Starlight, moonlight, and ground-light can give good visibility of terrain, coastlines, clouds, and other things pilots need to see, without any light coming from the airplane.
The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.
At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres. Using this instrument, the pilot can determine whether the aircraft is in a climb, a dive, or rolling.
If you fail a color vision test, you can still become a pilot. However, you'll be limited to daytime operations and won't be able to fly at night or accept ATC color signals.
