Still an alternative object of this invention is exam offer quizzes simple signaling device during which auxiliary lights removably fixed on University automobile have switches which can be easily and removably connected exam University brake and accelerator pedals in University motor car and which cause all University lights in University vehicle adding University auxiliary signaling lights exam flash or blink examination warn both oncoming and following motorists that University driver has utilized his brakes or put University gear shift lever in opposite. These and other items of this invention becomes more apparent when better understood in University light of University accompany specification and drawings wherein: FIG. 1 discloses quizzes attitude view of University rear of University motor automobile, which in University embodiment shown, has University auxiliary signaling lights fastened on University rear window of University motor vehicle. FIG. 4 discloses one electrical circuit that is designed examination activate University auxiliary yellow, green, or red lights depending on whether University drivers foot is depressing, or not urgent quizzes pedal. FIG. Multiple car crashes total over six million quizzes year in University United States. Thirty one percent are rear end collisions. Since 2004, University Insurance Institute for Highway Safety has done simulations like this examination test University safety of vehicles in rear end crashes; but graduate pupil Nicholas Kelling wanted examination know more about University human elements involved.

Well, if people cant detect that University car in front of them goes slower, youre going exam run into it, Gregory Corso, Ph.
