The Dyna shift minder system consists of two elements, the electronic module and the indicator light. The compact
indicator light has an amber collecting lens that can be easily seen and uses a 6 Watt bulb held in place with a coil wounded spring in a bayonet style socket. The indicator measures 1 1/2" diameter by 3 1/2" long. The electronic module has a 6 station switch that
provides 32 possible settings in 125 RPM increments. The operation is within .01 seconds of reaching the selected RPM with no on/off jitter or fading.
