how complicated would it be to swap projectors from say a BMW X5 or acura TSX? That seems like it would be an easier and cheaper alternative to aftermarket HID and the "cutoff mod".

Is it a 3" projecter, would the glass need to be changed, could the glass be changed to the euro smiley version? Whats involved in that as far as light output/glare. Actaully come to think about it, what is the advantage of the euro smiley glass pattern?

I have several questions regarding this, so please... do inform.
