Mr. John F. Doerr 100 Lefferts Ave. 4D Brooklyn, NY 11225

This is in reply to your letter of December 12, 1986, to Secretary Dole on your "Safety Light Warning System." You have asked if your system "could legally be implemented" and for advice "how I may go about marketing this system."

The patent drawing of your device depicts a light bar mounted in the rear window area with a green lamp in the center flanked by amber lamps, with two red lamps at the end. This system would be acceptable neither as original equipment on passenger cars, nor as replacement equipment on passenger cars manufactured on or after September 1, 1985. As of that date, Federal Motor Vehicle Safety Standard No. 108 requires passenger cars to be manufactured with a red stop lamp in the approximate location of your green lamp. There is no Federal prohibition against offering the system in the aftermarket for retrofitting on passenger cars manufactured before September 1, 1985, but the system would be subject to the laws of each State in which it would be sold or us ed. I understand that Oregon and California allow green-amber-red deceleration warning systems when the lamps are mounted on the rear of the car, but restrictions may exist as to their mounting in a vehicle's interior.

I hope this information is useful to you.

Sincerely,

Erika Z. Jones Chief Counsel

Mrs. Elizabeth Dole Secretary of Transportation Department of Transportation 400 7th Street NW Washington, DC 20590 Dear Mrs. Dole:

Subject: SAFETY WARNING LIGHT SYSTEM

I know you are concerned about rear end collisions, extra "eye-level stop light" confirms this.

I have a patent on this system which I believe will be more effective. This system consists of a small green light st eye-level which burns when you are gaining or maintaining speed. When you release the accelerator the green light goes off and the yello w or amber caution goes on, on each side warning the driver behind you to be alert which gives the driver a second or more to react, then, if you apply the brakes, caution lights goes off and normal stop light, lights go on, on each side at eye-level.

This information was sent to all auto makers in the United States and some abroad. They like the idea but are not interested in negotiating with me, as they don't accept ideas from anyone other than their own engineers.

I am interested to know if this could legally be implemented and if you could give me any advice or information as to how I may go about marketing this system.

Enclosed, is a brief description and my patent # 4,470,036.

Sincerely,

John F. Doerr Inventor
