The first emergency or first response vehicle in use would have been a horse drawn petrol wagon in and around the 1880's. Then in the 1900's there would have been motorized wagons. These would have had some kind of lighting but not the instantly recognizable Light Bars LED we see today. The history of emergency and police vehicles is an interesting one. Whilst those first vehicles would not have gotten to a scene very quickly they were still probably the fastest things on the route. Without these first vehicles we would not have the excellent first response teams we have now. So what does the Light Bars LED actually do, how does it work? The modern Light Bars LED is popular because it can be seen round a 360-degree angle, which is crucial when a vehicle is stationary. The new generation LED lights are extremely bright, so bright in fact they can be seen in bright sunlight. This gives the Light Bars LED an advantage over other forms of lighting like halogen or tungsten bulbs. The main function of the light bar on any emergency vehicle is safety, they warn other road users and they highlight stationary vehicles and scenes. LED technology is not new. It has actually been around since the 1920's and was invented in Russia. In the 1960's the LED lights were used by General Electric in the United States. Mass production of LED lights didn't happen until Hewlett Packard used them in early calculators. So the Light Bars LED have a long history to rival that of the emergency vehicles they are now fitted onto. It seems fitting that the LED lights and emergency vehicles have almost the same length of history! Light Bars LED is popular not just because of the superior lighting they provide. The LED bulbs contain no toxins or mercury, they don't attract bugs as they don't emit UV light (the main thing that does attract bugs) and they generate no heat, which makes them cool to touch. Another huge plus is they use less battery power than other lighting options and can therefore be used uninterrupted for lengthy periods. Light Bars LED don't generate radio frequency waves, which means they don't interfere with TV or Radio signals. All in all the Light Bars LED are made for first response or emergency vehicles. Indeed some manufacturers of Light Bars LED work very closely with police, fire service and medical agencies in order to provide specific light bars to suit their needs. The light bars in production today are manufactured to high standards, beware of cheap imports though as they will be poor build quality and likely to fail and be unreliable. Emergency vehicles and Light Bars LED are the perfect combination
