So airplanes and other aircraft won't crash into them. So airplanes don't hit them. FYI, Airport Towers have a rotating beacon that has a white light that shines out several miles and on the back of this is a green light. This helps aircraft locate civilian airports in bad weather.

Why are lights on radio towers sometimes white sometimes red sometimes blinking sometimes not and change from day to day?
Not 100% Certain, but based on my observations, I'd say it's either due to the type of structure it is, and how tall the structure is.
