The most universal and easy to use shift light available! The compact Digital Shift Light (DSL) 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 bright enough to alert your senses into rowing the shifter at the exact RPM. You can even program up to four different RPM rates for different gears! The DSL can be installed on single cylinder engines up through 12-cylinders on stock ignitions or high powered aftermarket systems.

MSD 89631 - MSD Programmable Digital Shift Light Details
Note: Supplied with a GMR pickup. The GMR is a little device that simply attaches, no slicing or cutting, to a current carrying wire and turns that information into a 12-volt rpm signal. This signal can be used to activate the Digital Shift Light. It makes installation even easier on diesels, points, coil-on-plug and most any other applications.
