Stack ST539 Sequential Shift Light Array

Multi-Stage Shift Light Module
Key Features    
Stack's (ST539) Multi-Stage Sequential Shift Light ("shiftlight") Module features 5 ultra-bright LEDs - 3x amber, 1x red, and 1x blue, which illuminate sequentially to give a clear visual warning to assist the driver with the optimum timing of gear changes.

Each Individual LED shift light can be programmed to illuminate for a specific engine speed value (RPM), so regardless of whether you are running a rumbling V8 or a screaming sports bike, you can setup the shift light array to meet your specific engine requirements.
