Lightbars for Emergency Vehicles
This article will place the focus on Lightbarsand their use specifically for emergency vehicles. We will also explore different Lightbarsand their applications, with emphasis placed on their use on emergency vehicles.
Lightbarsare simply elongated tubes upon which light bulbs are placed. The tubes are covered in a glass or plastic dome to protect the inside, although the dome might be used to give a particular color of light. Some of the popular Lightbarsare halogen light bars. These use halogen lighting and are steady burning. Halogen Lightbarsare perfect for use as emergency lights as they are bright and can illuminate well in the dark. They are made to be mounted on almost any surface and are preferred by emergency workers who use them at night as they enable them to see what they are doing. They are inexpensive and very energy efficient compared to ordinary bulbs. The quality of the light is also greatly improved. Halogen Lightbarshowever burn out relatively quickly as they are lit for long periods of time.
Strobe Lightbarsare also very wide spread in their use for emergency purposes. They are used mostly on emergency vehicles. Unlike the halogen Lightbars, they produce a flashing light and are capable of producing a number of flashes per second. Strobe Lightbarsare mounted on emergency vehicles and are used as an identifying feature. They are switched on when the vehicle is responding to an emergency and warn drivers that they should give way for the vehicle to pass. Strobe Lightbarsconsume a lot of energy and it is not uncommon for them to drain the car battery of emergency vehicles. They also get very hot and produce intense heat, which can burn someone or set fire to flammable material that may be near the Lightbarsduring its use.
The newest innovation in Lightbarsis the LED light bar. It is also commonly used on emergency vehicles to warn drivers of an emergency. They use very little energy and so are favored by emergency vehicle operators. They also have a larger variety of flash patterns and are also capable of producing more flashes per second than was initially thought possible. The LED Lightbarsare slowly replacing strobe Lightbarsfor use on emergency vehicles. They are also more environmentally friendly than their predecessors and have the quality of light produce is much better. These advantages have made them a favorite. LED Lightbarsare very expensive, a crucial factor that has slowed down their progress.
There are also portable Lightbarsthat are made specifically to be used by undercover police officers or volunteer emergency workers who want to hide their identity. They can be dethatched from the vehicle and stored away. These are usually used inside the vehicle and can be placed on the dash, visor or behind the back seats of the vehicle. These are however specially manufactured to prevent them from flooding the car with light.
