Now if you're goin to retrofit a HID into a stock headight housing probably you need an adapter to fit your D2r or d2s bulb.Not really sure kasi di kopa na try tong route na to.

korak. afaik, most hid kits here have the d2s bulbs. ang pinaka difference ng d2s sa d2r is the d2r bulbs have carbon paint on specific areas of the bulb to minimize glare. these are installed in afaik the HID-ed 06 civic and the corolla altis S (?) not sure ha.
