Emergency vehicle lights are specialized lighting systems used on vehicles like police cars, ambulances, and fire trucks. These lights are designed to alert other drivers and pedestrians of an emergency situation, allowing the emergency vehicle to navigate through traffic safely and quickly. They often use bright colors, such as red, blue, or white, and can flash or rotate to increase visibility. The use of emergency vehicle lights is regulated by law in many regions. When these lights are activated, other vehicles are typically required to yield the right of way, ensuring that emergency responders can reach their destinations without delay.
