Lights Police Vehicles Can Put To Great Use

Lights police vehicles will find use for need to be reliable

, energy efficient and very bright. Light emitting diodes usually fulfill all these criteria. LEDs have a lifespan in excess of 50,000 hours, extending up to 100,000 hours in some cases. They save a lot of energy by providing impressive luminosity even at a power rating as low as 4 6 watt. A combination of the bright output they provide and the long lifespan translates into great cost effectiveness as well as energy savings. That is the reason LED light bars are most commonly used for law enforcement vehicles.

The LED Lights police vehicles flash, on dark highways, have great brightness. This is because Generation III and sometimes, even Generation IV LEDs which are known for being ultra-bright are used. Sometimes, the parameters of the lights are greatly controlled in advanced light bars to enhance the lighting efficiency. For example, the angle of a beam can be varied to make it a narrow 10 degree beam or a wide angle 40-degree beam. You can have rotating strobes for 360-degree visibility. Diamond mirrors and slide-in lenses installed between strobes can ensure 120 180 degree visibility of the lights if required. Chrome deflectors and diffused lenses are used to expand the coverage of the lights when brighter lighting is required over a larger viewing area.

One of the most incredible features of modern lights, police vehicles use is their ability to flash at great speeds. You can have 70 bursts of quad flash in a single minute. In some cases, the FPM can exceed even 200. Such a great rate of flashing enhances the light visibility making them unmistakably prominent especially at night. This is the reason highway patrol cars, emergency, service, medical and maintenance vehicles all use these light heads. Modern technology even allows you to sync several different LED modules or even light heads in varying colors to flash in alternate phases or in synchronization. The high output lights flashing alternately or simultaneously can be very effective when you need powerful warning lights.

The LED bars mounted on police vehicles have a sturdy but slim design. They have excellent thermal management for heat dissipation, accomplished with the help of extruded aluminum casing. There are a vast number of mounting options for lights, police vehicles need to have. These options include L-Brackets, swivel mounts with suction cups, magnetic mounts, slide bolt mounts and stainless steel straps. Snap-on and Velcro straps are also used in some cases. It is possible to replace a light head on advanced light bars by just opening a single screw, which speaks volumes of their efficient design.

The Lights police vehicles need should not only be bright and flashy but also reliable. Once again LEDs come to the rescue. Unlike other light sources, they dont die abruptly but instead get dimmer and dimmer with time until it is time to replace them. Moreover, since you can configure several LED modules, it is not possible to be stranded without emergency lighting.
