The FAA requires all airplanes to have a solid green light on the right wing, a solid red light on the left wing, and a solid white light on the tail.
These are called "navigation lights".
They are also required to have a red beacon (aka "anti-collision light") on the top or bottom of the fuselage, although some
planes have it on their tail.
Strobe lights are required on the wing tips and tail.
These lights are required by law to be on every plane (and helicopter), and to be turned on from sunset to sunrise . When they are not there, or they do not
behave as they are legally required to, that is a good sign that you are not looking at a normal plane. Also, planes do not hover, or turn from a ball of light into
a plane. Real planes also make noise, and are not totally silent.
