Different police lights do different jobs.
Policemen are luminous human beings. On every crowded road they are recognized separately because of the brilliant police lights that their vehicles flash. When they are outside the vehicle also, all policemen carry hand-held tactical police lights. In other words, different types of police lights, that keep them glowing much of the time, are the constant companions of policemen during the various duties that they have to discharge.
Light bars of various sizes, strobe lights, and light sticks, are the warning lights used in police vehicles. Light bars are the more conspicuous among these police lights and the latest technology is steadily being incorporated into it. Some of the light bars have speakers and sirens within it. Some others are fixed on rotators which can turn the bar a full 360o. Yet others will have reflectors.
All police lights used on vehicles will invariably have two colors, blue and red, which are mainly used for warning. But most vehicle police lights will have blue, red, amber and transparent lights. Light sticks are police lights that are generally smaller than light bars and are used at the rear of police vehicles for directing traffic. These will have pretty much the same colors as light bars, and different flash patterns are used to use it as warning light, or traffic control light, as situation demands.
Police flashlights may be less conspicuous than the brilliant lights of police vehicles, but his flashlight is every policeman’s man Friday. While flashlights are crucially important for police on night patrol, policemen need these police lights during much of the day also. Chasing people through dark alleys, and searching in ill-lit basements and cellars, are among the more common tasks of policemen. A flashlight is an indispensable duty gear for them during such chores. Even in normally lit rooms, too often a flashlight is necessary to search things underneath a sofa or a cot.
As in the case of police lights used on vehicles, police flashlights are also being continuously modified by the integration of new technology. Nowadays there are flashlights that can do the job of a searchlight as well as that of a metal detector. These police lights will start vibrating when they are within a certain distance of metals.
Then there are flashlights, which hide a pepper spray within it. These police lights with built-in pepper sprays are very effective defense equipment because when a policeman raises his flashlight, adversaries will not suspect that he is going to spray pepper and are unlikely to duck. So the results are bound to be faster and instant.
And with or without pepper spray or metal detector, a flashlight may occasionally double as a weapon of impact for defense purposes. Since there are several varieties of these police lights to choose from, those who have the tendency to raise a flashlight as a weapon to shock may ideally go in for a heavier variety.
Police lights, whether they are flashlights or vehicle lights, are generally fluorescent lights or LED lights, as different from incandescent bulbs. These are more energy efficient than incandescent ones as they can produce much brighter light with the same amount of current. Since a higher color range is also available in both these, they are in every way suited for use in police lights.
