How do you turn on the headlight on the Vitilan i7. I know it sounds stupid but I can't find a way.

The headlight can be turned on with the a press of the button on the side of the controller. The controller is the thing with the power button and the "+" and "-" buttons. On the right side of the controller there are two buttons. One of those buttons is the headlight button.

From the manual:

By pressing the button, the controller will turn on the headlights and the display backlight will turn dark; by pressing the button again, the controller will turn off the headlights and the display backlight will resume its luminance.
