Why ambulances have a different light?
in Bulgaria and Russia were red lights of ambulances, Russia also had blue lights. Why all Europe (without Spain, there are ambulances with amber lights) have ambulances (emergency vehicles) is illuminated in blue and light not red. In so far as I know in USA emergency vehicles such as ambulances, fire trucks and police have red lights, it is in Japan and Australia. Tell me why Europeans have all emergency vehicles with blue lights?
Blue Headlights ambulances can cut through the dense fog in the European Region, where most countries in the winter / fall season have thick Climate Foggy. Therefore, the blue lights are more visible the Reds in this situation.
