This. I suggest you head over to hidplanet.com and start reading. Or shop to try to find some already made. A retrofit is likely the only way you will get true HID though. I also suggest looking at the morimoto minis (d2s and H1) if space is a concern(not sure how big civic lights are). Although the FX-Rs are fairly small as well. If you decide to go the FX-R route, let me know. I have a set I never ended up using and I'll sell them to you for much cheaper than theretrofitsource(that's where I bought them so you know they're quality)
