Not a company. Just an idea with a patent and prototype. Alpha numeric display to be mounted on the rear of a tractor trailer rig. The premise of SAYBOX is; "Safety through communication". Unit displays any one of 7 basic predetermined messages at any given time and is controlled by an existing dash mounted interrupter switch found in the tractor. One wire connects the unit with the trucks factory installed marker lights, near it's installation sight. All message content, display time, and flash time is predetermined. Unit is hermetically sealed and no changes can be made after point of sale. Basic Messages are as follows: 1) THANK YOU 2) TOO CLOSE 3) DIM LITES 4) CAUTION 5) WIDE TURN: DONT PASS 6) REVERSING 7) EMERGENCY.
