I often wonder where such nonsense originates. Such lies can spread fast.I was taught that if you turn the headlights on for a few moments you get a few more amps to the starter.
Turn the lights on and you then have LESS amps for the starter motor. Subtract the amps the lights draw and that is what you have left to run the starter. So lights off is best.
My gas motorcycles automatically turn off the lights when I press the starter button, even if they turn on with the ignition key. A couple of them keep the lights out until idle RPM is reached. They do this to get more power to the starter and ignition when starting.
