Abstract: The notion of an easily retrofitable passive lighting-safety device designed to be generally installed into the existing rear lighting wiring-circuit of any motor-vehicle from motorcycles to cars and trucks, --so as to significantly boost a following driver's visualacuity cognition threshold of awareness regarding the state of a leading vehicle's sudden breaking procedure. The invention provides an intense quasi-precognitive white-light "flashback" alerting effect, preferably appearing (particularly under nighttime conditions) as a nearly subliminal approximate 100-200/millisecond flashback of visually non-deacclimating "white-light", emanating from a vehicle's existing back-up lights (or integrated with the DOT high-center brake-light). The effect being to essentially arouse a following motorist's attention to the simultaneous light-up of the preceding vehicle's stoplights. Regardless as to how long braking action continues, the so called STOPWHITES.TM.
