i mean buy the hid bulbs and stick um into stock sockets?
Real HID bulbs comes in 3 kinds:
1) D2R - "R" stands for reflector. These bulbs have built-in shields and are designed for reflector housing.
2) D2S - "S" stands for shield. These bulbs don't have built-in shields and are designed for projector housing with shields.
3) Rebased bulbs - These are essentially D2S/D2R bulbs with modified bases to fit OEM housing. For example, to fit a 2000+ Celica, you would need the H7 rebased bulbs.
Keep in mind, even with the rebased bulbs, you would still need to modify your spacer or use piano wires to hold the bulbs in place.
I have a HID kit from an Infinity G35 with D2R bulbs. I was able to use the stock clip to hold the bulbs in place. The D2R/D2S bulbs are similar to H7 in size. So, all three bulb types will fit our projectors. I installed Mcculloch HID kit (with rebased bulbs) on Renee's car. And I have D2R on mine.
I have tried a lot of different brands of "HID" bulbs before going with the reall thing. MTEC is by far the brightest. Nokya is the prettiest (in terms of color). And I had PIAA Ion Yellow fogs for a long time.
