To turn on the headlight of your GOPOWERBIKE, make sure that
the LCD Display and the battery are both turned on.
As soon as both the LCD Display and Battery are on, hold
down the UP arrow button for a few seconds.  Now your GOPOWERBIKE headlight
should be on. Enjoy your ride.
(Please note that turning the headlights on is the same
process for all GOPOWERBIKE models that have headlights included)
