ATTACHMT: ATTACHED TO LETTER DATED 3-22-90 TO KENT D. SMITH FROM STEPHEN P. WOOD, NHTSA; [REDBOOK A35; STD. 108]

TEXT: I recently submitted an invention on a safety device to the Office of Crash Avoidance Research in the U.S. Department of Transportation. William A. Leasure, Jr., the Director of this office, responded to my letter but referred me to your office because there were some legal questions involved.

I believe that vehicles need some way of signaling following drivers if the headlamps of their vehicles are blinding you. I am a Driver Education teacher and whenever my students confront me with this problem there is no solution that up to now is ef fective. My invention, which is designed to deal with this problem is this: A button on the dashboard is attached to the backup lights. When the button is pushed the backup lights will go on and off in a matter of a second or less. The lights would not come back on again unless the button was pressed a second time. If necessary the button could be hooked up to only one of the backup lights. This would eliminate any confusion on the part of the driver of the following vehicle as to which direction th e car may be going. An alternative could be to hook the button up to the license plate lights. If this were done a double filament light would have to be installed so that the increase in intensity would be immediately observable by the driver of the f ollowing vehicle. This method of installation would not violate the SAE Standard for backup lights but I dont feel that it would be as effective as having the backup lights momentarily activated. I firmly believe that this new innovative concept would give the driver an effective means of informing the driver of the following vehicle that you were being blinded by his inconsiderate action.

I'm aware of the Federal law that states that the backup lights should not be on when the car is going in a forward direction. I believe that the intent of the law is to force people to make repairs so that those lights will not stay on and therby co nfuse people into thinking that the car is backing up rather than going forward. It would seem to me that this new concept could be added to an automobile without violating the intent of the federal law concerning backup lights.

I explained my idea to a gentleman from the Utah Department of Public Safety. He felt the idea was good enough that it should be pursued even if it meant making a revision in the Federal law that governed backup lights.

Would you please offer me any recommendations, either positive or negative, in regards to this invention. I thank you for your time and look forward to hearing from you in the very near future.
