First responders often have to face the lack of apathy from careless drivers, busy with their iPods and cell phones. Police lights, are of great help, to request right of way, under such circumstances. These emergency signals help to clear traffic, so as to enable drivers get to the scene faster. These lights give a complete 360 degree view, so that they are seen from everywhere. Emergency vehicles often have to travel at a high speed. With the help of these police lights, emergency vehicles can let their fellow drivers know, that there is an emergency, and they need a clear right of way. Police vehicles also, often stop at places that are dark .These police lights help to inform the general public about the presence of an emergency vehicle. These lights are generally placed on the top of the vehicle, on the dashboard or even integrated into the vehicle. Police lights have undergone a lot of changes over time. What previously used to be red flashing lights are now replaced with light bars that appear to dance around the vehicle. The latest entrant in this category is the full dual color LED light bar that can change from a combination of red and blue, to amber instantly, with the click of a switch. Speaking of colors, red, blue, yellow and amber are the most commonly used lights. The combination of these lights would vary to a certain degree depending on the situation, and the state, that the emergency vehicle is being used in. A combination of red, white and blue or red and blue is a popular combination used by many states. However the combination wouldn’t change drastically so as to confuse the driver. As earlier said, the combination also changes depending on the state of emergency. For example when chasing a criminal, police vehicles generally need to flash their lights very brightly. Because these lights are indicators of an emergency, the general public is restrained from using them. Of course, you can use LEDâ€s on your cars, but remember to never use colors that are similar to emergency vehicles. In fact there are many states that have restricted the use of LED lights to mere turn signals, emergency flashers, and flashing lights during a funeral. Besides the police, ambulances, fire engine trucks and tow trucks are allowed the use of police lights. There are a number of shops that sell these lights. You could also source them through online stores. Emergency vehicle users generally buy them in bulk as they are often used for a fleet of cars rather than for single use. Buying these in bulk is cost effective as well.
