Of course, there are exceptions, and these come in the form of FAA exemptions. The U.S. Air Force received an FAA exemption to FAR 91.209, allowing night flight without external lighting illuminated.

According to FAR 91.209 you need to have your position lights on from sunset to sunrise.
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.
Planes have headlights so that pilots can see what is in front of them. Unfortunately, they are only effective during takeoffs and landings. Even with the slight illumination offered by the headlights, only darkness is visible when looking out the front window of a cockpit.
A dark scene spread with ground lights and stars, and certain geometric patterns of ground lights can provide inaccurate visual information, making it difficult to align the aircraft correctly with the actual horizon.
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.
Thanks to aircraft lighting systems, see-and-avoid collision avoidance is often easier at night. But there are illusions that can play havoc with your see-and-avoid scan. Autokinesis is one such illusion. If you stare at a stationary light against a dark background, it will appear to move in time.
Some airlines & airports do have late night/early morning flights. They aren't frequent because many airports shut down at night because of restrictions on flights taking off of landing during certain hours. There is also a decrease in demand for those later flights and they aren't profitable for the airlines.
Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. 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.
In smaller aircraft, you will have a good view of the area around you, depending on the canopy. In larger aircraft, the instrument panel and cockpit design can restrict your outside view a bit more. Below you will find two pictures taken from the cockpit of a Super Dimona HK36, used for VFR general aviation flights.
Aircraft Instruments that Help the Pilots See in CloudThe pilots also have a weather radar which can be viewed on their screens and this can help them determine what type of cloud it is they are flying through (or approaching), how much water there is in the cloud, and if there are more clouds behind it.
The FAA has an online tool to calculate sunrise, sunset, and civil twilight for any given location. For 14 CFR part 61, section 61.57(b)(1) night operations that meet recent flight experience requirements, the term “night” refers to the time period beginning 1 hour after sunset and ending 1 hour before sunrise.
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.
