Rally Series and Vector 3 Series Status LED Lights
The Rally series and Vector 3 series power meters feature status LEDs on the end of the spindle located on the inside of each crank arm. Single sided power meters will only have a status LED on the left pedal. The pedals do not flash an LED when the batteries are low in order to conserve the remainder of their life.
