Rotating emergency lights
Rotating lights provide a visual warning of dangerous conditions and obstacles. Rotating lights with LED lamps create a beam of rotating light. Rotating lights are one of the important traffic tools to warn vehicles. Flashing lights on ambulances, fire engines, and police cars allow first responders to reach the scene quickly. Sometimes, their blinking indicates caution. Tow trucks, cement trucks, and other large vehicles use light bars to alert other drivers of the load being carried.
