You can turn on your front and rear lights by holding the plus (+) button on the control pad. Be sure not to hold the minus (-) button, as this will activate walk mode, which will accelerate the bike to a speed similar to walking.

 

While holding the plus (+) button, you will see an icon pop up on your display indicating the power of your lights. To turn off your lights, hold the plus (+) button until you see the icon switch off on your display.
