In the heat of competition racing - or even the everyday morning commute, which can seem like competition racing more and more - you need to know where the optimum shift points are. Your ears might be a good judge of this, although a look at the tachometer is the ideal practice. Sometimes however, it's just not a good ideal to take your eyes off the road for even a second. That's why you need an MSD Shift Light. This device uses cutting-edge micro circuitry in order to alert you as to when to shift up. The MSD Shift Light can be calibrated to illuminate at specific RPM points that you determine. It's designed for use with all standard, electronic and Vertex ignition systems, and is available in a wide range of RPM shift point ranges. You can get your MSD Shift Light right here for the lowest price. In fact, if you find it for less at a competing website, let us know and we'll meet or beat their price.
