The Shift Light Module allows you to use any LED-style light (300 milliamp maximum) as a fully-programmable, stand-alone shift light. By accessing the engine RPM off of the V-Net you can program up to six separate shift alarm signals. Each shift point is user-programmable using the DatalinkII software. Shift light module does not include the shift light. This module will also show you when the shift light was triggered to come on.
