Abstract

A new illuminated signal to following vehicle drivers is disclosed. This signal would inform the driver of the following vehicle that the driver of the lead vehicle had removed accelerator pedal pressure. The following vehicle driver may anticipate the deceleration and braking of the lead vehicle. So fore-warned, the driver of the following vehicle may also remove accelerator pressure, preventing the following vehicle from inappropriately approaching the rear of the lead vehicle, and the need for heavy brake action. This advance warning of lead vehicle deceleration and braking will decrease the reaction time needed by following vehicle drivers to safely brake after the lead vehicle brake light is observed, reducing the potential for rear-end collisions. This new light signal, indicating removal of accelerator pedal pressure in the lead vehicle, would cease whenever the lead vehicle brake is applied, or the cruise control is switched on.

Claims

1. ) Throttle position responsive vehicular rear facing status light apparatus comprising the combination of:

visible light generating electrical energy to optical energy transducer apparatus disposed in a rearward facing orientation on a rearward portion of a first vehicle, in either the traditional left and right fender areas, the rear window deck area, or a center high-mount position;
