Five Features That Fire Truck Light Bars Must Possess
Fire truck light bars play the crucial role of helping the fire trucks cruise through traffic so they can reach the spot of fire accident at the earliest. The lights for fire trucks available today have been fitted with LED bulbs so they produce intense bright light and prove to be indispensible accessories.
Fire truck light bars are mounted on the roof of the fire engines and are very important to attract the attention of everyone around. The effectiveness of these light bars ensures that the path for the fire engine is cleared very quickly, which in turn helps in putting down the fire quickly before much damage is done. However, these light bars have to possess some basic characteristics in order to be highly effective. The first and foremost characteristic of the light bar is its sturdiness and dimensional stability. With a length in excess of 60 inches, height of 5 – 6 inches and width of 12 inches, most light bars are designed for uniform weight distribution, in order to prevent damage to the roof of the fire engine over a longer period of time. Besides, the light bars are designed with aerodynamic styling so that the drag resistance on the vehicle is lower, helping to accelerate to a greater degree.
Fire truck light bars should have a rugged construction. This is achieved through nylon and polycarbonate base and domes, sealed to extruded aluminum platforms, a combination that is extremely resilient and at the same time light weight as well. The sturdiness helps in preventing the rattling noise of the light bars, makes it portable when the light bars have to be used on multiple fire engines and also keeps them intact in spite of heavy duty handling.
Fire truck light bars should be resilient to all kinds of weather conditions, and have to operate for long hours irrespective of whether there is wind, snow, rain or fog. The light bars have efficient thermal management thanks to the aluminum casing which makes the heat dissipation very efficient. On top of that, the lights are moisture resistant thanks to the sealed base and vibration and corrosion resistance, largely due to anodized aluminum bases. The resistance to vibration is important to ensure that the effectiveness and functionality of the LEDs is not really affected by the vibration of the speeding fire engines.
Fire truck light bars need to possess two more important characteristics which are very important to their overall utility. Firstly, the light bars should have dozens of built in flash patterns which enhance the visibility of a fire engine even at a great distance. These flash patterns should be easily operable and it is an added advantage if the light bars have the benefit of non volatile memory to store the information about the last used flash pattern. The other important characteristic is the control over the various lighting parameters. Advanced fire light bars provide beam temperature and beam angle control to keep tab of the lighting coverage. In some crisis situations, focused beams penetrating through dense smoke will be required while in some cases wide beams for good lighting might be needed. Besides, it is important to have good control over the flashing rates and even rotating rates if rotator strobe lights are present on the light bars as well.
