A lightbar is a series of lights that is manufactured to provide high quality and reliable signaling to drivers on the road.

These lights are bright and denote the presence of the police officer. The next light included in the lightbar is the rotating light. This is a more dynamic light that works in a rotating mechanism to provide light that is seen in all directions. Most of the time, the combination of the rotating and the steady burning lights combine to create a conventional light bar. There are still more lights that are used.
