Some States in the US also do not have a compulsory headlight on law.
The Department Of Transportation (DOT) is the ones that require the headlight to always be on in order to import the motorcycle to the US.
That's why I removed the jumper wire to make the headlight switch operable.
As for electrical power, my 2011 G5 is running a 40 watt headlight bulb + the other small light bulbs and at speed, the voltage in the electrical system is 14 volts.
It remains at 14 volts at an idle unless I hit the brake lever or pedal.
That knocks it back to 12 volts at idle speed.
Although I'm guessing, I think with the engine at speed, a 65 watt headlight plus a 20 watt brake light just about maxes out the alternators output.
