The hazard lights, also known as the emergency flashers or hazard warning lights, are designed to alert other drivers to a potential hazard or emergency situation. When a car is involved in an accident, the impact or damage can trigger various safety mechanisms in the vehicle, including the automatic activation of the hazard lights. There are several reasons why this happens:

• Safety precaution: The automatic activation of the hazard lights is a safety feature designed to increase the visibility of the vehicle involved in an accident. By quickly alerting other drivers to the potential danger ahead, it helps prevent further accidents or collisions.

• Warning to other drivers: Hazard lights indicate that there is a problem or hazard on the road, such as a disabled vehicle or an accident scene. It signals to other drivers to exercise caution and be prepared to take appropriate action, such as changing lanes or slowing down.

• Communication with emergency services: In some cases, the automatic activation of the hazard lights can be linked to other systems that communicate with emergency services. This can help emergency responders locate the accident scene more quickly and provide assistance.
