ABSTRACT:
An early warning brake light system provides an accelerator pedal-mounted sensor and simple circuitry connected to a vehicle's existing brake light switch circuit. During a panic stop the sensor attached to the accelerator pedal activates the early warning circuitry and immediately delivers current to illuminate the rear brake lights, even before the brake pedal has been depressed, giving trailing vehicles an advance warning that the lead vehicle will be braking.
