The part I am meaning is the one that lights the "power on" lite on top of the motor housing above the handle lock. It is a white plastic piece that has two clips on it
There should be a little black cradle that it clips into ontop of the motor just behind the headlight cap, underneath the red lens on the outer shell...
On the top of the black cradle, there is a clear indicator lamp that you have to clip this to. The 2 fingers that you see on the top of the white light bulb holder are actually like springs that keep the holder tight against the bottom of the black cradle after it's clipped to the little clear bulb lens.
