The light for the 3rd Gen Firebird started its name as KS01. Later got revised to 4164, 4 is the generation of control circuitry, 1 indicated it was for the Firebird, and 64 was the amount of LED's.
Pictures showing the first design, where is was multiple circuit boards linked together. This later changed to a 64 LED long board that was snapped in the middle and rejoined to create the point. LED's on a 7mm pitch, fitted the car very well onto the original fixings of the car.
If you wish to make this light, the drawings of the polycarbonate are below. A complete package of PCB files and firmware for the microcontroller will be posted on here.
