Define "ride at night" If you are talking about grabbing some groceries or some mild trail riding the stocker will be fine - all 35W of it. For serious night riding you are looking at HID for head light and helmet.
I have a UFO dual light up front, will wire both lights for high beam when I get the proper switch. It's hard wired on one light right now, seems to work fairly well. Here's an example:
My '06 DE300 has the small ignition with the map switch on the bars.
When the Red River M/C Club allowed me to help them with the first Last Man Standing, I found myself running errands in the dark. (Like a dummy, I had neglected to bring my headlight to the meet.)
I borrowed a Trail Tech from a friend who was also working the event on his CRF450x. Within five minutes, I had it strapped on and plugged in. It worked great!
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..
LED is the future. Good now and getting better, not quite up to HID but a lot of white light for very little power consumption. Large input voltage range as well, so you can get by with a rectifier and capacitor instead of a battery and regulator.
