There is a difference in what the FAA requires and Airline procedures.
The Nav lights are located on the wing tip and tail. Left is red, right is green and tail is white. The help other aircraft tell your orientation at night. They are required to be on sunset to sunrise.
LAND is the Landing light, used to land at night. Recommended below 10,000 feet for collision avoidance.
Strobe is a high intensity light usually one on each wing tip use for collision avoidance. Normally turned on just before takeoff.
Beacon is a small, red rotating or flashing beacon also used for collision avoidance. Normally turned on before engine start.
Airlines use NAV light any time electrical power in on the aircraft.
Pilot controlled lighting allows you to control the lights separately.
