Plug and play HID, LED or Xenon headlights?

Hello,

Are there plug and play HID, LED or Xenon headlights out there for sale? Looking for a set that will just require me to take off existing headlights....and then installing new ones. I recall seeing that there are JDM LED or HID ones, but I believe they need a harness to be plug and play? Also, do they come with LED or HID's or is it just housing? Thanks!
