Heavy duty LED lightbars are designed to provide emergency vehicle lighting in the toughest of conditions. LEDs can be relied upon for their long operational life, their bright lighting and their extremely impressive energy efficiency. With simple 1W LEDs, it is possible to put together modules that can provide bright lighting whose parameters can be controlled as per the requirements. The light bars that make use of LEDs can be powered by simple 12V DC power supply owing to the low amp draw of LEDs, which in some cases is less than 2 3 Amperes. With reduced heat dissipation and optimal use of energy, LEDs provide luminosity that can rival any alternative of much greater power wattage.

The number of 5mm LEDs used in an LED module varies from as low as 4 to sometimes over 16. Some LED linear modules even have multiple stacks or arrays of LEDs. It could be possible to have dual coloured LED modules and split segment modules which have LEDs of multiple colours like red and blue, amber and blue, etc. 8 12 super bright, Gen III LEDs can provide a highly effective warning signal with minimal dispersion and maximum visibility. The visibility of the LED lightbars is further enhanced through built in flash patterns which can be used to attract attention, especially when there are lots of other lights glowing around.

Some full length LED lightbars are programmable to flash in more than 50 different flash patterns which is incredible considering the different kinds of signals they are capable of passing. Wide angle optics is used through double Fresnel lenses to enhance the coverage of the beams. Advanced light bars meet SAE requirements. This means they are secure and reliable. Multiple light heads mounted on a single light bar can be synchronized for a more powerful warning signal. Individual light heads provide equal light intensity if required, although it is quite possible to control them independently. Even more importantly, the light bars can be controlled as a whole and also in groups, like front facing light heads and rear facing light heads. Modern light bars come with a very user friendly interface to scan and select a desired pattern too.

The LED lightbars can be mounted with the help of swivel brackets and suction cups as well as with stainless steel straps. The extruded aluminium platform provides vibration resistance as well as efficient thermal management. The light bars are also well designed for uniform weight distribution and the sleek chassis is aerodynamically efficient. Some light bars have an electronic module, to provide appropriate input power to the LED modules, which are also well secured against voltage spikes and short circuiting. The individual components of a good quality light bar are rigorously field tested to make sure they will last through heavy duty usage and bad weather situations. The modular construction of modern light bars makes it easy to repair and replace individual parts too if required, which makes them easier to handle.
