I haven't done this conversion on my Versa yet, but I have bought almost a dozen kits from
http://www.vvme.com for various motorcycles either I or my wife are riding. The quality of the kits has always been more than adequate, and to date I have not had any issues with any of the kits. I put a set in one of my motorcycles last year and it has more than 35,000 miles on it now with no problems at all.
You are looking for the STANDARD H4-3(9003) BI-XENON HID KIT. These have a small electromagnetic base that moves the light source to simulate the double filament function normally found in an H4 bulb.
When choosing a color temperature, do not follow the standard US of A rule of "bigger is better". The 4300K light color is the whitest light, and provides the greatest number of lumens. The higher you go, the lower the amount of lumens you will get. The 3000K color temperature is more of a fog color.
