Brake Light:
Explanation: A brake light is a safety feature in vehicles that illuminates when the driver applies the brakes. It is typically located at the rear of the vehicle and is designed to alert other drivers on the road that the vehicle is slowing down or coming to a stop. The brake light is an essential component of a vehicle's lighting system, along with the headlights, turn signals, and taillights.
When the driver presses the brake pedal, the brake light is activated, signaling to drivers behind that they need to reduce their speed or come to a stop to avoid a collision. This helps improve overall road safety by providing clear communication between drivers on the road.
