If I remember correctly, those use H3 bulbs and don't have particularly good output.
If you want a cheap plug-and-play solution, check out the "Sonar" projectors.
If you want a slightly more expensive plug-and-play solution with much better output, get the BLS headlights (Blackbird Lighting Solutions is a sponsor).
If you don't mind doing some work, you can install OEM or Aftermarket HID projectors into the stock housings or a pair of aftermarket housings. There are threads on that in the Lighting FAQ. Lighting FAQ
