The light output from a Recon projector is a full circle, no cutoff at all. If you put a hid bulb in them you get two rings of light with really dark areas in the middle, just like a Maglight flashlight that has been twisted completely out of focus. Even if you could adjust the bulb inside the housing to focus them, they have zero cutoff and would be two complete circles of light.
To retrofit a real HID projector into a Recon headlight you need:
1) A Morimoto Retro-Quik System that includes a recon/spyder headlight adapter plate to mount the projector in the recon housing ($300 with H1 bulb and ballast or $150 if you already have those)
2) Then a Bi-xenon MotoControl 9008/H13 harness so your lights don't go out every time you activate the high beam solenoids ($35 for this)
3) And finally some OCI Butyl Rubber Glue to reseal the headlight ($15 for this)
To accomplish the retrofit you need to take the headlight apart and dremmel the back of the headlight housing because the Morimoto projectors are slightly larger than the crappy recon projectors. Then you need to reseal the back of the housing with something like JB weld epoxy and put the headlight back together.
Spyder headlights (which are recon copies sold on ebay) actually have a better projector than the Recons, better CCFL halo rings, don't use a permanent glue like the Recons so they are easier to open, and they're cheaper. The Retro-Quik was made for them so you might not have to dremmel the housing of the Spyder headlights, but I'm not sure about that. If you attempt this retrofit and don't already have Recon headlights, I would try the Spyder headlights out first.
I'm actually in the middle of this project right now. I already had crappy Recon headlights so I decided to hack them up and see if I could make something better. I got too busy to work on them for a week, but the first one is almost done and I can give you some pics when I'm finished.
