Modern police lightbars are highly reliable for several different reasons. Firstly, they make use of LEDs which are known to last for more than 50,000 hours in most cases and can be used for both internal and external lighting, in all weather conditions. Secondly, the light bars come with a highly resilient chassis which is either made of die-cast aluminum or black polycarbonate that is lightweight, but at the same time lends moisture and vibration resistance to the light bar. Lastly, the light bars are a collage of several light heads which ensures that they are functional even if one or two light heads aren’t operative. Moreover, advanced light bars have a modular construction, which makes all the components easily accessible for service, upgrades or repairs.

police lightbars usually comprise of halogen strobes as well as LED lights. The predominance of LEDs these days is largely because of their reliability and great energy efficiency. LEDs are capable of producing high luminosity with just 4 – 5 Watt rating. It is possible to configure as many LEDs as you want which lends further flexibility when ...
... you use LEDs. In fact, 5mm 1 Watt LEDs, are assembled together in rows of a dozen each to create LED modules which are then configured together for bright lighting. Although the power rating of such an assembly is low, the brightness is unmatchable.

One of the most advanced aspects of modern police lightbars is that you can go on upgrading them or keep on adding more lights. A full-fledged light bar can be installed with multiple LED segments, corner LED modules, front and rear facing strobes, side facing LED modules and staggered strobe lights to ensure 360 degree visibility. This extended collection of different lights makes the light bars highly functional. However, what really takes these light bars to the next level is the interconnect harness which can be used to sync the flashing patterns of all these individual light heads when you want a loud and bright warning signal to go out. In fact, it is also possible to separate out groups of light heads into phases which can then be independently controlled. You can benefit from simultaneous, alternating or circular flash patterns, with slow and fast flash rates.

police lightbars have a low profile design for fuel efficiency. Moreover, the low height ensures that air drag resistance is kept to a minimum. Thermal heat management through an efficient casing that acts as a sink allows you to keep the lights turned on for long durations. Some light bars have o-ring seals which protect the LEDs from being affected. The weatherproof, water resistant light bars are also made vibration resistant with the help of shock plates which can absorb high impact. Technically sound engineering has also permitted the use of replaceable lenses, which are smooth and clear and help in focusing the lights from the LEDs when required. The rear, front and corner assemblies are also dust and corrosion resistant.
