History of Emergency Lights

Decades ago, lights were not yet introduced to the law enforcers. In the 1990s, civilians and policemen had the same look of cars thus, people had a hard time distinguishing if there is an urgent matter. It was no big deal and a sense of urgency was not yet existent. Only in the 1930s, people started to place a signal light in red color to grab the attention of citizens. It was later improved with the invention of the spinning gumball type of light. In the 1960s, police lights were turned flat and parallel to the top of the vehicle. The blue light was also added to make it easier for people with color blindness to determine its meaning and implication. Eventually, other light colors were used for different kinds of emergencies.

Modernization of Emergency Lights

Today, we have what we call police light bars, which are enhanced and developed versions of the signal light in the 1990s. Due to the advancement in technology, these light bars are more efficient and visible for civilians. It is now in a light-emitting diode or LED source which is more convenient, reliable and efficient. Light bars can now be effortlessly placed on top of a vehicle. There are some which can be fitted in a bracket and some made in magnetic base. It goes with different sizes depending on the need of an enforcement group. These LED bars are built to go well with sirens or speakers which can intensify the attention of people and the kind of emergency situation. Installation of this is hassle-free and smooth. A police officer in a rush can quickly execute the light placement in just 3 seconds.
