During normal operation, the RED light will be off and the GREEN light will be on steady when no
speed signal is present and flashing when a speed signal is being received.
If the RED light is flashing rapidly, then the cable is stuck and not able to turn. Some stock
speedometers may become very stiff at low temperatures (below freezing) and not allow the cable to
turn. Make sure your stock speedometer is in good working condition.
