Cartek Shift Lights and Gear Indicator

Enjoy an F1-style light show as you go up through the gears! These compact units signal you with a 5-stage series of green, yellow, orange, and red LEDs.

Programming couldn't be easier. Simply run the engine up to the RPM where you want the first stage to begin -- just for an instant -- and back off. Then run up to the final stage RPM and back off. The internal computer calculates the other three RPM levels for you.
