Does the 2004 Rx8 Headlights(HID/non-HID) fit the 2005 rx8 connector(HID/non-HID)? How many pins do they both have? Are you the same or different? How is the HID different from the non-HID headlights? Please answer the questions. Thank you

 

The wiring would be OK, even if you had to splice wire-to-wire, there is no basic difference between the HID and Halogen lights.

If you bought OEM xenons and put them in an original Halogen car, the self levelling motor wouldn't work, but no big deal.
