Originally, the blue light from used payphones is to be used in contact with the bobbies, suggested radios (the ones the doctor Tardis fame) It's been fitted with a light blue umbrella flash made when the station needed to Bobby speak. The fire was the star of the blue lights on the street and was dyed to meet the boys () in a blue uniform, so that the use of police cars for the use of color was blue, was adopted as an emergency light as even as the blue light recognized emergency
more gradual change since the 1960s that began the use of radios to replace pay phones
