Strobe light bars are widely used in emergency vehicles

As strobe lights are used in different types of lighting, a car strobe can be used to power any of these. Police vehicles may use small strobe lights with one side measuring as little as less than 10cms, or may have them as part of large beacons, or in light bars. 360o rotating strobe light bars are used in many emergency vehicles to ensure all side visibility. Smaller lights are mostly mounted inside the vehicle.

The purpose of any emergency vehicle is to respond to an emergency at any point of time and usage of some sort of an audio and visual warning device is mandatory. There cannot be a single police car or an ambulance that does not have a warning device installed on it. When strobe lights were introduced initially, there weren't many options available. Most of the times, the first thing that draws your attention when you see an ambulance or a police car is the rotating beacon light or a strobe light bars, mounted on top of the vehicle, but nowadays a strobe light bars can be seen on the sides or on the tailgate. The light bars, which are designed using the latest strobe technology, facilitate usage of dual colors simultaneously.

Hospitals, police and fire engine departments rely upon strobe lights due to their various extensive and outstanding features. The different flashing colors used each time draw the attention of the other vehicle users at the right time. It's imperative for the people on the roads to recognize the color code used in the emergency vehicles. Only police cars and ambulances can use certain types of strobe light bars with color codes.
