There are many different types of internally and externally mounted lighting equipment for an emergency vehicle. The performance of the equipment can be measured in terms of a large number of parameters too. High end emergency lighting equipment usually provides better lighting, better control, greater resilience to bad weather conditions and heavy duty handling and a longer life. When you are looking for emergency lighting equipment, you have to match the parameters versus your necessity to arrive at the conclusion. For example, an LED light head can give you luminous flux of 2000lm. Another powerful module might provide luminous flux in excess of 6000lm.



Similarly, the working temperature range of the emergency vehicle lights too is larger for high performance, sophisticated lighting equipment. LED lighting in general can be expected to provide very high degree of efficiency, sometimes over 85%, saving quite a lot of energy for the same luminosity. The operating voltage of LED lighting is usually between 12 – 24 V DC and a 6 outlet power supply is usually provided along with the rest ...
... of the kit. The kit also includes 10 foot power cords, shielded cords which are weather resistant and most importantly, synchronization harnesses. These prove useful when you want to connect multiple dash or deck lights and make them flash in synchronization with each other. This helps in creating a highly powerful signal to relay cautionary or warning signals over a long distance.



For an emergency vehicle it is important to have lighting that can be operated with ease and under all conditions. Modern light heads have a sealed polycarbonate base along with rubber grommets to protect them from moisture. The external body is of anodized aluminium which protects light heads or light bars from excessive vibration of the vehicles as well as from high impact. In some cases UV resistant shockproof glass or plastic is also used in order to protect the LED lighting elements. This equipment is structurally rigid and can be mounted on the roof of the vehicle, adjacent to the external windshield or above the bumper or grille. A built in electronic flasher helps in varying the flash patterns as per the requirement so that you don’t even need an external flash controller device.



An emergency vehicle would largely benefit from a wide angle design of the lighting. 120-degree coverage is extremely important for the lighting. In some cases, optic spreader filters are in place along with internal Fresnel lenses to expand the lighting in either direction. The emergency lighting kit also includes optional driver side and passenger side exit cables, pigtail connectors and mounting hardware. For externally mounted emergency lighting equipment, two aspects of design are very important. It is ensured that the weight distribution of the lighting equipment is uniform to avoid putting pressure on thinner vehicle roofs. Similarly, the dimensions are such that the thickness or height is always less than 3 to 4 inches. This sleek aerodynamically stable profile is important to reduce drag resistance on the equipment and thereby, on the vehicle.
