The led light bar has caused a stir particularly in the world of emergency lighting. It has been hailed as a brilliant alternative to strobe light bars. A led light bar is an efficient source of power, and produces more light per watt than most lights. The intensity of light and the efficiency of the light bar itself are not affected by shape or size of the light bar unlike fluorescent light bars or tubes. The effectiveness of the light can also be seen in the on/off time of the light bars. The led light bar takes under a microsecond to attain full brightness. Led lights can also emit the intended color light without the use of colored domes, color filters or other traditional methods for changing light color. This means that the cost of production goes down, as well as with less components, there is less that can go wrong with the light bar.

There are however disadvantages associated with the use of a led light bar. There is a very high initial cost for installing a led light bar, and this may deter someone on a low budget from making use of this technology. There are other light bars that may work almost as well and cost less than half the price of the led light bar. The life of this light bar is also dependant on the temperature of the operating area. If it is constantly used in places with high temperatures, this will reduce its working life as well as make it susceptible to breaking down.

This is not good especially for emergency vehicles that are required to work in places with different temperatures.led light bars have also raised concern that their constant use might exceed what eye specialists call blue-light hazard. This is specifically a concern with led lights that are blue or cool white. These may damage the eyesight of the individual using a led light bar as well as those around.
