* Visibility for the colorblind

There are many theories as to why red lights are used on police cars. Perhaps, the most commonly accepted theory as to why cops flash red lights is to avoid the risk of color blindness.

People who can't see the blue or yellow spectrum of light rarely have a problem seeing red-colored lights. This helps to ensure that everyone on the roads can see the police vehicle easily, even when it is flashing continuously

* Stop

Normally, the red flashing light means only one thing - stop in any case! If a police car is using red flash, you must stop as soon as possible it doesn't matter what the circumstances or conditions are.

Aside from that, if cops overtake your car and stop at a distance while flashing red lights, you must immediately stop and park behind their car.

* To alert

Red light is the symbol of emergency. When a patrol car is flashing red, it indicates a critical situation and alerts the people in that surrounding.

* Day time

Blue or yellow light is hardly visible in the daytime. Unlike these two, red light has better visibility and wavelength during the day. This makes them suitable to attract the attention of locals even during daylight.
