Single Stage Shift Light with Autoshift Output

With a highly visible shift light, you don’t need to worry about missing a shift. You will get consistent results, shifting at the exact desired engine RPM each and every time. With the aid of a Schnitz shift light, hitting the rev limiter while going down the track is a thing of the past!

Seven bright red LEDs visible in direct sunlight. Easy wire-up directly to the coil.  RISC processor for extreme precision and easy user interface. Simply press and hold both program buttons to enter into program mode, where you can set the desired cylinder setting and shift point setting. The new settings are then stored in memory.

Dimensions: 3.125″ long x 0.75″ diameter. The most compact shift light of any manufacturer! Two different style Mounting Brackets. Vinyl covers are for reducing emitted light intensity for night racing. They do not determine the color of the emitted LED light. Covers match the LED color.


The auxiliary output wire (brown) can be used to ground a circuit (switches to ground) with the RPM is equal to or great than the shift point.  This is perfect for wiring up to a relay for auto shifting with an air or electric shifter! It is recommended to install a toggle switch inline with the brown wire so this output can be disabled if need be. You must use a relay to activate a shift solenoid. We offer a kit right here.
