Police lights are bright, flashing lights mounted on police vehicles, typically in red and blue colors. These lights serve to alert the public and other drivers that a police officer is responding to an emergency or conducting a traffic stop. The use of these lights helps ensure safety by making the police vehicle more visible, especially in low-light conditions. In addition to red and blue, some police vehicles may also use white or amber lights for specific situations, such as traffic control or road safety. The patterns and intensity of the lights can vary, with some jurisdictions having specific regulations regarding their use and visibility.
