I used to run a car lighting business sold and hundreds upon hundreds of DDM Tuning HID Kits. They work very good for the price! I've ran DDM Kits in all of my cars, trucks and motorcycles.

A 35w kit produces a lot more lumens than our stock 55w bulbs do. So just stick with a 35w kit. You don't need a relay harness or anything.
Here is a picture of my bike with my HID's on...
(Those are 10000K bulbs)
Patton - I literally am a complete moron when it comes to installing anything electrical. Are you telling me that this 35w kit is completely plug and play? Just pop in a couple of new bulbs?? No other electrical work needed?
If so, this is my next purchase! Since I commute on it, I WANT people to see me coming.
