High intensity flashing white lights are also employed to identify tall structures, such as chimneys and towers, as obstructions to air navigation.
What are the red lights on top of buildings for?
They have red light to avoid collision from aeroplane and helicopter, by putting red light pilot gets notification that there is some object. This is called aviation light or Aircraft warning lights.
Why do towers have red lights?
Why do the flashing lights on cell towers change from white to red at night and back to white during the day? Red light allows for your eyes not to lose their lesser ability to see in darkness like white light would in a night time environment. The eyes adjust between red light and darkness better than “white” light.

Do all cell towers have lights?

What are the lights on a runway called?
Runway End Identification Light Frequently named as Runway Threshold Identification Light (or RTIL), this is a white flashing light, unidirectional, that identifies beginning of a runway. Unlike approach lights, there only two RTIL lights installed per one side of a runway.
Why do planes lights flash?
Strobe lights are flashing white lights on the furthest left, right and, on larger aircraft and some smaller ones, back points of an aircraft. They are the brightest lights on the aircraft, and are used to signal that an aircraft is entering or approaching an active runway, or for visibility in dark, clear sky.
What color do planes flash at night?

Why should you not use red lights at night?
Short answer is because human eyes don’t respond well to the color red, so it’s a very poor color choice for illumination purposes. Longer answer is the whole idea of having lights at night is to be able to see things at night. Human eyes are more sensitive to green and yellow, less sensitive to blue and red.
