Abstract: The automotive safety brake light is a supplemental optical signaling system that generates an illumination visible from the exterior of a vehicle. The automotive safety brake light mounts on a rearview mirror such that the field of illumination of the generated illumination is visible from the anterior side of the exterior of the vehicle. The automotive safety brake light generates the visible illumination when a brake signal from the vehicle indicates that the plurality of brake lights have been activated. The automotive safety brake light comprises a circuit housing and a control circuit. The circuit housing contains the control circuit. The control circuit monitors the brake signal. The control circuit initially generates the illumination as a series of pulses when initially actuated by the brake signal. The control circuit subsequently continuously generates a continuous illumination until the brake signal indicates that the plurality of brake lights are no longer illuminated.
