For HID you need DC current,, the lighting on these bikes are ac I believe same as KTM. There is a conversion to float the ground and make DC or put a bigger stator in. get a bit more "juice".. I floated the ground on my old 97 which had the ducati energia stator that is like the Eline add on systems.. Had about 160-180w of usable power. I was running an65-85 w halogen hyperwhite osram bulb in a ufo ghibli headlight on that bike.. it was nice at night..
