The Pro-Shift is an independently operating shift light with advanced microcircuitry. The shift-point is selected by inserting a precisely calibrated rpm module "Pill" into the unit. The amber light activates when the engine reaches the chosen rpm. A variety of clearly marked rpm module are available. "Pills" Note: #5340 may be adjusted to 4-6-8 cyl. #5341 & #5342 are fixed to 8-cyl. but may be used on 4 or 6-cyl. by using less chip. For example, 4-cyl. installation with 3,000 rpm chip will "light up" at 6,000 rpm.
This LED shift light is a replacement option on Auto Meter tachometers with the larger size light or any other accessory RPM triggering device.
