Optimizing gear shifts is one of the most effective means of reducing lap times while increasing engine longevity. A shift light helps the driver to achieve perfectly-timed shifts.
This red shift light is designed for easy hookup to any Stack tachometer (ST200 Clubman, ST200C Classic, ST400 Professional, ST400C Classic, and ST901096 Chronotronic) without any modification. The Panel model is designed to mount in a 1/2" diameter hole in your dash panel. This style is preferred in formula cars and sports racers, where there is no horizontal "dashboard" between the instrument panel and the cowl.
