I'll chime in with everyone else. Installing projectors into a halogen reflector housing and getting them properly aimed, secured and sealed involves quite a bit of labor. It might sound easy, but think about it, you've got to cut the halogen housing, probably heat the housing and remove the front lens, then mount and adjust the projector for the correct height and rotation. You've also got to make sure the projectors are pointing forward (not left or right). Then you've got to properly secure and seal everything.... You might as well go all the way with some OEM type HID projectors. Everything else is 2nd rate.

I've been doing research on this, and I've decided to go with hidplanet.com'* $400 complete zenon kit

It includes E46 BMW / Audi TT single zenon projectors, ballasts, oem bulbs and a few other misc parts, all new. I'll definitely post the results when I complete the conversion. Probably June or so...

Ive already done this before just not on this car! So I already know whats involved! And installing these projectors now and switching to HID hardly involves anything but unscrewing a light...Im in close relation to the person I bought the projectors from, he gave me his complete honest opinion on the projectors and what will happen when I switch to HID and I chose this to be a good way to do it! So all I can say to you guys is to wait it out till this weekend so I can show you exactly whats happening here! I'm supposed to recieve them tomorrow so I will take pictures of my stock headlight on and the projector on as well against a wall to show the difference! And another thing about the bulbs, yes the bulbs he gave me are junk, he told me that before he sent them, but I could put any bulb in there I choose! Which will eventually be Sylvania Silverstars...He just threw them in the box becuase he had them laying around! No Biggie

we are not questioning the ease of swapping, we are questioning the quality of the halogen projectors when used with an HID bulb vs using a true HID projector. Especially when an HID projector is not a huge invesment

well what he has told me that with these being an OEM projector he said putting in HIDs arent really going to be much different than having true HID projectors...he told me that comparing apples with apples for the price it will be a good projector...He did also tell me that the cut off line may be a little fuzzy but that isnt the biggest deal to me

That is a LOAD of crap. Projector quality varies HUGELY!!! I can not even being to explain the amount projectors vary. Yes they are all projectors, but quality, beam width, cut off, beam lenth, intensity, etc change dirasticly.

IMO, I would begin to question your source. I am in no way trying to get you not to do projectors, I would like you to realize that if you are going to do halogen projectors and then go to a HID down the road then you need to pick a projector that can go between both with good results.

But you also seem to not want to change your current idea of your project so go right ahead, i'll be the guy in the background laughing when the results aren't worth the amount of work you put into it.
