An LED lightbar is most commonly seen on top of cop vehicles or construction vehicles as an effective emergency lighting mechanism. The light bar comprises of one or two rows of super bright LEDs which are cased together with in-built flasher patterns. There is a reason why the design of a light bar has proven so effective and has taken its place as one of the most preferred types of emergency vehicle lighting. The design of the light bar is sleek and it is usually light and stable enough when mounted on top of the car or truck that needs emergency lighting. Most common light bars are about 12 inches wide, 2.5 inches high and about 40 - 72 inches long, weighing around 6kgs.

The LED lightbar is usually made by assembling 2 or 3 LED modules, each comprising of 2 or 3 rows of LEDs connected together. 6 super bright LEDs can product light of high intensity. Each module usually operates with 6 - 12 LEDs each. The biggest benefit of the light bar is its design, which allows you to replace one malfunctioning module without really affecting the functioning of the light bar. However, it is to be noted that LEDs ...
... have an unusually long life span exceeding 40,000 hours which means you would hardly get a chance to replace them. Moreover, the light bars are ideal for emergencies because, LEDs don’t die abruptly. They instead get dimmer and dimmer, allowing you to gauge the need of replacing them whenever required. A 12 – 24 V DC power supply would be enough to support the lighting offered by an LED bar, which is another reason why they are preferred for emergencies.

The ease with which you can mount, install or remove an LED lightbar gives you another good reason for using them. Simple screws will allow you to fasten or remove non-functioning modules which can be easily replaced. Interconnecting cords are provided along with the kit for putting together the circuit. You can choose for corner modules as well, to ensure the lights are flashing in all directions and not just in the front. A simple push button cigarette switch will help you turn on or turn off the lights in the rear, front or on the sides or change the flashing pattern.

The LED lightbar is manufactured with in-built flashing patterns. 8 – 10 different patterns of blinking could provide plenty of permutations and combinations, especially when there are modules of differently colored LEDs. Removable opting filters allow you to get greater variety out of the whole assembly. If that isn’t enough, there are lenses too, which can enhance intensity of the light. Split color center sections provide you with even more versatility, making light bars indispensable for highway patrol cars or those being used for road clearance. The custom designed programmable modules can be made to flash at high frequencies, depending upon the urgency of the event on hand. With the help of mounting brackets and clips and sometimes mounting magnets, it is possible to install them with ease.
