Understanding Brake Lights
Brake lights are an essential safety feature in modern vehicles. They are designed to alert other drivers of your intention to stop or slow down, thereby preventing accidents and reducing the risk of collisions. Brake lights are typically located at the rear of the vehicle and are activated when the driver presses the brake pedal.
There are two types of brake lights: stop lamps and turn signals. Stop lamps are designed to indicate when the driver is applying the brakes, while turn signals indicate the direction of the vehicle’s movement. Both types of brake lights are critical for safe driving and are regulated by traffic laws and regulations.
