Denial's come with a hi/low bean circuit so just take the low beam wire to an accessory wire, the other wire taps into the high beam wire on the bike. I have still not installed the high beam wire as I need to locate the wire that runs the shutter in the headlights so I have them both hooked to power which is an option in the install page. I posted to see if someone could identify that wire color for me as I cannot find my old manual.
I took the bike out for a night ride yesterday, taking back country roads and wow...with my new HID fog, headlight and the LED driving lights it lights up the road in a clean, white light that is so bright the reflective speed limit signs look bazaar, the look like a brilliant white glowing ball on a stick a quarter about a 10th of am away. The driving lights are about as same brightness and range as the HI beams the HID's are pretty amazing as well. The HID Fog lights really light up the road about 100 ft down the road so they fill the dark area just in front of the bike. With everything on at once the front of the bike is a big white light ball when viewed from the reflection in a storefront glass. Very happy with the results!
