THE ENLIGHTNER
Update May 31, 1995
"The Enlightner" replaces the third, center, high-mounted brake light as used in most modern day vehicles.
The light (or lens) has two colors, Red and Amber. The top half of the lens is Amber and the bottom half is Red.
Amber signals "Caution" and the Red signals "Stop" to the driver of the vehicle following a vehicle equipped with "the Enlightner".
Functions of "The Enlightner":
1. The Red portion is lighted when the brake pedal is applied, with the ignition "ON" or "OFF". This function overrides all other functions.
2. The Amber portion is lighted when the transmission selector lever is in any forward position with the accelerator pedal and the brake pedal not depressed. When the brake or accelerator pedals are depressed, the Amber light is "OFF".
When the transmission lever is in Reverse position, the Amber light flashes constantly at the rate of 90 flashes per minute. The flashing is continuous regardless of accelerator pedal and brake pedal positions as long as the transmission selector lever is in Reverse position. This give a warning to everyone behind the vehicle that it is in Reverse and it about to back up or is backing up.
When the accelerator pedal is released ("OFF"), the Amber portion comes "ON", giving a "Caution" signal to the driver of the vehicle behind the vehicle equipped with "The Enlightner" that deceleration is taking place. When the accelerator and brake are not in use, the Amber portion is lighted. When power is reapplied by depressing the accelerator, the Amber light goes "OFF". When deceleration is taking place, Amber is "ON". When the brakes are applied, Amber goes "OFF" and Red comes "ON".
The advantages of "The Enlightener" over similar products is that it keeps the driver following behind totally informed (enlightened) as to the functions of the vehicle ahead. "The Enlightener" will reduce rear-end collisions (one of the most common accidents) and reduce highway traffic injuries and fatalities.

"The Enlightener"
According to U.S. Government statistics, there are over 10,000,000 highway accidents annually costing Americans $98,100,000,000 with an average cost per accident of over $9,800. Of the 10 million accidents, 25.3%, or approximately 2 1/2 million, are rear-end collisions.
The average reaction time, from the instant the brake signal on a vehicle is seen until the brakes on the vehicle following it are applied, is 3/4 of a second. At 60 miles per hour, a vehicle travels 66 feet in 3/4 of a second. After the brakes are applied, the stopping distance for a car travelling at 60 MPH is a minimum of 146 feet. Therefore, the total distance from seeing the brake signal to a full stop is at least 212 feet.
Introducing "The Enlightener".........
featuring a Deceleration Caution Signal (DCS) in addition to the traditional third brake light. The instant the vehicle accelerator pedal is released and before the brake is applied, "The Enlightener" signals deceleration or a change of vehicle operation. It is estimated that the use of "The Enlightener" will reduce rear-end collisions over 41% and prevent thousands of highway injuries and fatalities. The reduction in costs to Americans would exceed $10.1 Billion annually.
In addition to the Deceleration Caution Signal (DCS), other features of "The Enlightener" include the DCS being illuminated when the vehicle is in any mode other than stopping or normal forward motion, and a flashing caution light when the vehicle transmission selector lever is in reverse position.
"The Enlightener" is truly a unique innovation for improving highway safety that will save hundreds of lives, prevent thousands of injuries and save Americans billions of dollars annually.
