Abstract
A visual deceleration indicator signals to pedestrians and other vehicles that a vehicle is slowing down or coming to a stop. Illuminating devices, such as LEDs, contained in a license plate frame located in the front of the car or otherwise, are activated when the vehicle decelerates. An accelerometer or other sensory device detects deceleration and sends a signal to illuminate the LEDs, thereby letting others know the vehicle is slowing down. The license plate frame may be connected directly to a rear brake light component without the use of accelerometers or other sensors. When the brake is applied, the LEDs in the license plate frame are illuminated. The LEDs may be contained in other forms and located in different positions on the front or side of the car. The indicator might be one color to indicate braking and another color to indicate it is on, but not braking.
