Emergency Vehicle Light And The Different Variations Used In Modern Equipment

Emergency vehicle light is useful to alert motorists on the road about an impending

danger or about a critical situation that requires the emergency vehicle to speed through. Emergency vehicle lights are of many different types and are also complemented with sirens and other emergency equipment designed for reliability and longevity. These lights have received a shot in the arm through light emitting diodes, although halogen and xenon head lights and strobes are still used to certain extent. It is important to note that the lights have to be chosen carefully based on budget, the vehicle and the features required. There are light bars for example, with an assortment of features which are used on bigger vehicles and also standalone strobes that perform a variety of functions with their versatility.

Emergency vehicle light equipment using LEDs are considered more reliable because of the longevity of LEDs and also because of their design which is modular and easy to repair or replace. LEDs are energy efficient which has allowed even the bigger light segments to depend on small and simple 12 V DC power supply. Moreover, it is also important to make sure that the emergency vehicle lights that you pick offer variety and versatility. The lighting for example, can be flashed in several different degrees of intensity. The intensity modes including cruise lighting, bright intensity and low intensity can be used in different scenarios. Another variation is the use of built in flash patterns, sequences and bursts that make the light even more visible and attention grabbing. Some of the light bars have more than 50 flash patterns of different types to convey the criticality of the warning signal.

Emergency vehicle light need not necessarily be mono-colored. Modern dash and deck lighting equipment and even mini bars make use of split segments with arrays of LEDs in multiple colors. Therefore, LED segments in blue and red, blue and amber, amber and green, etc. are used to further enhance the effectiveness of the lighting. This variation in emergency vehicle lights is also possible because of the different colors of LEDs, strobe tubes, filters and lenses which are manufactured these days. The colors greatly increase the permutations and combinations as far as flashing is concerned.

The emergency vehicle light equipment proves to be useful with other variations such as the use of parabolic reflectors and wide angle domes. These optical elements used in modern lighting equipment enhance the quality of emergency vehicle lights, lowering the scattering and dispersion, increasing the reach and spreading the coverage. More powerful warning lights can be emitted thanks to the use of super bright LEDs making use of TIR and light house optics. Optic spreading filters and Fresnel lenses help in making the most of the light emanated from the LEDs. Lastly, the vehicle lights can be complemented with sirens too whose tones can be integrated with the flash patterns to create a combined, cohesive warning signal that cannot be missed by motorists on the road.
