I have been instructed to contact your office in an effort to determine any federal regulations that may apply to a new invention, which I wish to market in the United States.

This invention is a "Safe Driving Distance Indicator Light." It is a simple electric light that can either be built into the rear of an automobile or installed on the rear bumper. This light would emit one color (possibly green), which could be seen by the driver of a following automobile. If the following automobile is following closer than the "predetermined" safe distance, the indicator light that is attached to the lead automobile would change color, possibly from the original green color to red. This new color (red) would then be viewed by the following automobile, indicating that he is following at an unsafe (too close) distance.

The goal of this invention is to reduce the number of rear-end automobile accidents in the United States. The shape and size can vary from a small square device to a long, thin shape. The light would come on automatically as soon as the engine is started and automatically dimmed when the headlights are turned on. Refinements could be made by the manufacturer, such as incorporation of a manual or automatic adjustment for various road conditions or speeds. Although since the object of the apparatus is to act as a reminder or warning and not as an accurate measuring instrument, I feel that these would be unnecessary.

I am considering applying for a U.S. patent on this invention and would greatly appreciate it if you could advise me of any and all legal restrictions or regulations that would apply.

If further information is necessary, please feel free to contact me. Your prompt attention on this matter would be greatly appreciated.
