The green lights are actually two different sets of indicators for your EPIKGO. The lights on the left side of the board are to let you know that your EPIKGO is fully operational. When the board is powered on you will notice that one light should turn on. When an EPIKGO user steps on the board a second green light will appear, indicating that the board is in use. The third light on the left side will illuminate red if there is something wrong.
The green lights located on the right side of the board indicate the battery life. The amount of lights illuminated increase and decrease based on the battery power left in your device.Green lights indicate that the device is sufficiently charged while red lights mean the remaining battery level is below 10%.
