Bar lights are of several varieties, differing in terms of their dimensions, the number of light heads used, the lighting elements and the overall cost. One can pick and choose the light bars for different kinds of emergency vehicles based on budget. For example, the light bars for smaller police and patrol cars are cheaper and are designed to provide a decent range of features. However, bigger vehicles like law enforcement personnel vans, service crew vans, fire engines and fire rescue vehicles and municipal construction and tow vehicles need bigger light bars that can offer a greater range of features. Such light bars often cost in excess of $1000, but provide great value for the money, through some advanced features, added for a purpose.

For example, Bar lights are seen with rugged ABS or extruded aluminum housing. These are in place for integrated thermal management which ensures that the light bars don’t get heated up, even if all the dozen or so LED modules or light heads are operated at the same time for an extended period of time. It is important to make sure that these light bars are actually ...
... SAE and Class 1 rated, before using them during tough emergencies. Some of these light bars can be operated across more adverse conditions than others. This is why light bars are often marked with the conditions at which they can operate to peak capacity. Advanced light bars can operate even at very high temperatures or under water if required. Such light bars are rugged and robust and can weather high impact and heavy duty handling. Good quality light bars are even resistant to electromagnetic interference which makes them even more reliable.

The number of flash light patterns available in Bar lights is an important parameter. These flash patterns include varieties such as solid spotlights, randomly blinking light patterns, sequential and alternate flash and high output bursts. The effectiveness of light bars as far as built in flash patterns is concerned is because of the use of LEDs which can be configured to flash together at great flashing speeds. High flash rates can prove to be important to convey high danger alert signals across a long distance. This is why top manufacturers also use their own patented optics systems to send across wide angle, long range beams that can be spotted by distant observers too.

High quality Bar lights are effective because of use of unbreakable polycarbonate lens, colored filters and optic spreading elements. Parabolic deflectors are also used for beam control. The beams too can be varied based on the need. There are solid strobes mounted on advanced light bars that can produce narrow, 10 degree focused beams to highlight some areas. At the same time some light heads using 12-LED light heads can produce 180-degree beams. The external housing is epoxy or powder coated for corrosion resistance. Shielded weatherproof power cables and interconnectors are also part of the kit and so are a wide variety of mounting clamps and clips.
