MSD Performance 89631 - Digital Programmable Shift Light, 1-12 Cylinder, Single Point

The most universal and easy to use shift light available. Our new compact digital shift light can be installed on everything from 1 cylinder points-triggered engines to modular Ford engines with coil on plug technology. The tiny digital controller inside the compact housing gives you the ability to program the rpm activation points through the easy-to-view LED panel and two programming buttons. When the engine reaches the activation rpm, the six red LEDs illuminate brightly to alert your senses into throwing the shifter at the exact rpm. The DSL can be installed on single cylinder engines up through 12 cylinders on stock ignitions or high-powered aftermarket systems.
