Having experienced riding my Jackpiner at night with the motoplat ignition, back in the day, I would highly recommend getting the Preston Petty headlight with the battery. The Motoplat only supplies enough power to light up the headlight at high rpms. Thus if you are riding at night and let up on the throttle to slow down, you will only get a dim light at low rpms. Gets exciting when you are riding on a county dirt road in the middle of the night and have to slow down for a sharp turn.
