Different Types Of A Light Bar A light bar serves different purposes. This article will however focus in its use for emergency lighting. There are various kinds of light bar used on emergency vehicles to indicate that a motorist give way or pull over to talk to the police officer. One of these types is the strobe light bar. Strobe light bars work much the same way flash technology works. The principle is the same. A strobe light bar is favored on emergency vehicles because it can be seen from a distance, and the flashing light produced is very bright. The reason why this is so important is that emergency vehicles, especially those that are responding to an emergency travel at very high speeds. It is therefore important to make sure that the vehicle can be seen from a distance to ensure that the driver has enough time to react. A light- emitting diode light bar (LED light bar) is also a popular choice for use on emergency vehicles. This light bar is even brighter than the strobe light, as well as has even more advantages. LED light bars can be switched on for long periods of time without overheating or burning. Since they do not use a filament, they do not burn. The life time associated with LED light bars is also impressive, making them both a good and popular choice for emergency departments to use on their vehicles. A light bar may also be made of steady burning halogen lighting, essential equipment for lighting up the scene of an incident. These are used particularly at night or in low visibility condition such as for use to illuminate the area so that the emergency workers may be able to see what they are doing. They burn extremely bright and are made to use very little power so as not to drain the power source, as well as to be able to light for a long time without burning. They may also be found on the same light bar with strobe lights and LED lights. When we think of a light bar, we only think about those that we see permanently mounted on the roof emergency vehicles such as police cars. There are those that are made portable and detachable to provide for them being removed when they are not in use and stored away. These are preferred by undercover police and volunteer emergency workers in order to conceal their identity when they are off duty. These portable lights may be used on the exterior of the vehicle (mounted on the roof) or the interior (mounted on the dash board or visor). A light bar is therefore an effective tool in drawing attention to an emergency vehicle. This, paired with a siren ensures that the emergency vehicle gets to its destination on time and is able to avoid accidents, saving the lives of both the crew and other road users. Emergency workers should be careful to make sure that they choose the best light for use on emergency vehicles. They should also take into consideration the brightness of the light that they want to achieve as well as how long they want the light to work for. ...
