ABSTRACT:
An independent multimode safety and convenience apparatus for motor vehicles wherein real-time deceleration rate data is accurately communicated to following vehicles via amber and red lensed indicators. Rate of deceleration is converted directly to a warning signal on/off flash rate, amber in color. When deceleration results in a stop, the amber rate signaling is instantly exchanged for a steady signal of red color, automatically. Visible projection of this vital information for several hundred feet to the rear of a vehicle provides extra reaction time resulting in substantially enhanced risk assessment for following motorists. A sustained low speed mode offers compatibility with stop-and-go, bumper-to-bumper traffic. Automatically adjusting to this mode, the indicator then displays conventional red brake signals only. Tailoring operation in response to the monitoring of traffic conditions results in improved overall intelligibility. In no case does the indicator display both amber and red signals simultaneously.
