One of the most distinctive features about LED emergency vehicle lighting is the visibility that you get even in the harshest of weather conditions. There are quite a few aspects to be considered when you discuss the visibility of emergency lighting. The light has to be penetrative enough so that it is spotted clearly even in hazy, foggy or smoky conditions. Secondly, the light has to be flashy enough to grab the attention amidst a sea of other lights, which could be the case on a busy road or highway full of vehicles. Lastly, the expanse of the lighting should be impressive too, stretching horizontally as well as vertically to provide you good coverage. Modern light bars can be commended for providing you with all these aspects of visibility, through the use of technology and an intuitive design.

The high visibility of LED emergency vehicle lighting owes itself to the use of optical elements which enhance the light from LEDs. Clear, polycarbonate, replaceable slide-in lenses are used to focus the unidirectional lighting in the desired direction. Fresnel domes and double Fresnel lenses are also used for ...
... greater effectiveness of the lighting. The lighting provided by strobes is further magnified through the use of diamond mirrors installed in between the strobe heads to reflect the light. Similarly, large concave chrome deflectors are put to excellent use in order to make the most of the available lighting, to save energy.

The use of total internal reflection LED technology along with light house optics technology makes emergency vehicle lighting in the modern day, highly effective. The light can be made to penetrate across a longer distance and across a wider angle. You can control the angle of the beam, adjusting it between 10 degree and 120 degree or even more, depending on whether you need highly focussed spotlights or wider lighting coverage in dark areas. This is why LED emergency vehicle lighting is used for emergencies like rescue missions as well as for patrol vehicles which need to send out powerful warning signals to caution other motorists.

The visibility of the lighting is also enhanced through built in flash patterns. When the LEDs, which are usually configured in arrays of 6 or 12, blink in patterns, the visibility of the light is enhanced. This is because when lights turn on and off alternately, they tend to get noticed easily. Special patterns like triple flash and quad burst generate very high luminosity too. At high rates of flashing, that too with coloured LEDs, it becomes easy to catch the attention of other motorists on the road. The best part about LED emergency vehicle lighting in the present day scenario is that the lights are programmable and the segments can be easily repaired and replaced. Multiple segments work together to provide a brilliant output, which allows you to still have strong lighting even when one of the segments is non-functional. A simple push button switch for pattern selection and shielded inter-connectors also help in changing flash patterns and synchronizing the flashing of the lights respectively.
