Most HID kits involve simply adding a ballast between your existing factory socket connector and the new bulb. It's almost as easy as replacing a bulb:
* unplug the factory socket connector from your current halogen bulb
* remove the halogen bulb
* install the HID bulb
* plug the ballast socket connector into the HID bulb
* plug the ballast power connector into the factory socket connector
The only thing you need to do then is mount the ballast somewhere, which may involve drilling for a bracket. And if the factory socket connector is inside a housing with a cover, the wires to the ballast may need to run into that housing, if the ballast doesn't fit inside the housing.
If you don't want to be pulled over by the... er... authorities, buy the 6000K or lower HIDs. 8000K is a deeper blue, 10000K is really blue, and 12000/15000K is purple. Also, the higher the number, the lower the light output.
If you're going to buy them from an ebay seller, look for "digital" ballasts, and for high numbers of sales and high buyer comments (obviously!).
