Basic Questions for a New RX-8 Owner
 

I would like to replace the OEM headlights with better HID's and possibly Halo Angel Eyes. Any suggestions?

Is your headlight HID equipped (with a ballast)? On the Halo Angel Eyes, i think you need to replace the inside of the headlight housing or you need a new headlight housing. I like buying at eBay and they have what you need, check it out.

I'm not sure if I do have ballasts or not, but I appreciate it.

if your head light is non-HID you need to get the whole HID kit which includes ballasts to power the HID. or if you feel your wallet is thick, get factory HID's.
