The name Lightbar sounds quite uncomplicated and simple, but a police light bar is actually much more than a bar of light. Some of the police Lightbars are elaborate units, which contain within them myriad things like speakers, sirens, reflectors, and mirrors. The number of lights contained within a light bar may vary in different models. And besides its main lights, a light bar may have additional lights like takedown lights beneath it, and alley lights to the sides of it.In all types of Lightbars the lights will be enclosed in a clear dome. The light colors are basically red, blue, amber, and clear lights. In a Lightbar that uses halogen technology, there will be differently colored lenses inside the dome to project colored lights, whereas in light bars that rely on LED lights, the colored lenses are dispensed with, since color is intrinsic to an LED bulb.The most commonly noticed function of a Lightbar on a police vehicle is to demand other vehicles to clear the lane to let it pass.

Police lights are indispensable for police to see others as well as to show themselves to others. Wherever a policeman goes, whether in a car, or a bike, or a boat, or on foot, he is sure to carry a flashlight without which he might become more or less dysfunctional. A handheld police light could be as small as a finger or as large as an arm. The intensity and range of LED light bulbs, which are used today in most police lights, can be raised or lowered substantially to suit different requirements. As a result, by the flick of a finger a policeman can turn his flashlight to produce the effect of a spot light, or a reading light, or a flood light.And a police light may even do a job unrelated to lighting. Larger police lights may be used as a weapon of defense or offense under the duress of a situation. With all the jobs that these lights do, having them on their person is very important for the police.
