Police lights are the red and blue lights that use in an emergency. It was invented by a Superintendent of Signals for the Police Department of Detroit in 1920.
Police lights in the UK are blue only, unlike in the USA where they are blue on one side of the car and red on the other.
Chicago is famous for having only Blue lights on its police cars
A police car can generally follow you anywhere you can drive, warning lights on or otherwise.
Locally to me, the blue bar on the top of the car flashes (in some other states, I believe police use red lights, or red and blue) the headlights flash and the tail lights flash.
You can only have red lights on the rear of your car. And blue lights are illegal to use on any car on the street they are only for emergency vehicles blue lights are for police only
Police and emergency only.
They are "Confirmation Lights" which are the WHITE or BLUE light located directly above a Traffic Signal and are utilised by the Police to detect "Red Light Runners".It is "lit" when the lights are on Red.This allows the Police to see if anyone has run the red light.
It depends on what you mean by police vehicle. A vehicle with blue (or red depending on the locality) lights, a siren, and police markings? No, that would be illegal, at least in my state, and probably all others. In Tennessee, it's illegal to have blue lights or any police insignia on a vehicle unless it's an authorized law enforcement vehicle. You can however, purchase a vehicle with the same engine, suspension, and other specs as a police vehicle. A friend of mine bought a police spec vehicle a couple of years ago with everything except the blue lights and police insignia.
Red and Blue for law enforcement vehicles.
Typically, the strobes are blue and red.
