Old School EMS Ford Ambulance with Code 3 Lights

Why is it that they use red lights in the USA, and in the UK and main land Europe uses blue?. Does anyone know? Not that I have a preference, maybe a bit for the red color.

@2air4water Originally, one of the first police vehicles accidently had a red light attached to the front instead of a white spotlight. When people began pulling over for it, they kept it. Nowadays, fire departments and Ambulance corps are installing blue lights more and more... many times also, volunteers use blue lights when responding to a station, and those are to not be mistaken on the real trucks. Besides that, no reason, blue actually attract attention better.

@jojmr27 Ok. Well what attracts more is debatable. I don't know of research that underlines that observation. In the line of colors, yes you are right. Blue has a shorter wavelength and is more visible in low light. Red is used for that reason in the dark by covered operations for it's low visibility after a couple of meters but still provides light at close range. But new car lights with LEDs and xenon which also produce a slight blueish light can produce confusion on the road.

Whelen came out with these because back in the day, strobes were hard as hell to see during the day. So whelen, the papa of the low pro strobe bar came out with the advantedge rotators and strobes. Mixed with bix, fender, and grill strobes, they actually put on quite a show. Not to mention one you could drive easily in fog with. youtube: watch?v=latynB7YUF4&feature=fv­wrel
