Easy question! Two ways to go; 1-retrofit (pull parts off cars that use hid xenon bulbs. You need ballast/igniter/bulbs/wiring/projector lens then mount it all in your stock housing and wire it up, best solution as the projector lens is key and focuses the beam pattern.
2-Hid Conversion Kit (Find out what type of bulb you are using and buy the appropriate kit plug it in)
As a disclamer both not street legal..
touge - race - drift
gotcha covered!
