The MSD shift light has a built-in rpm sensing circuit that will turn the light on when the engine reaches a specified rpm. You select the rpm by using the same plug-in modules that are used with your MSD Soft Touch Rev Control.
This compact Shift Light features a bright LED that will alert you to SHIFT!
Fits neatly to your steering column or on top of the dash and illuminates bright enough to see easily in the daylight. This light plugs directly into MSD's line of programmable digital ignition controls. It can also be used with factory or other aftermarket ignition systems through an rpm activated switch.Learn More
