u really don't understand how projectors work. here:
see how the light path flips vertically in the projector... this is caused by the specially shaped reflector section that it comes with. also the blub has to be in the EXACT correct location for this all to work... move it an inch off in relation to the reflector and/or from the lens, and the focus is thrown completely off. notice that the cuttoff shield is at the bottom but the light it cuts off is going towards the top... this shields lights from blinding others on the road especially oncoming traffic or people you are following. putting this sheld in front of the lens would be useless as the light does not converge near that point.
notice that in the reflector headlight, like what we have stock, the light paths are NOT flipped by the reflector. as siad before, you are basically just putting a magnifying lens int front of the OE headlight. did you notice that there is actually a shield in that location on the OEM headlight so that all light coming out of the front of the headlight is being reflected from the back and sides of the reflector (you should not be able to see the bulb directly from in front)? removing this shield and magnifying the section of beam hotspot createdit, then adding a cylinder (projector shroud) to limit light leak to the sides of the reflector bowl (which is where more than 50% of the light thrown onto the road is coming from), will effectively undermind all the engineering that went into making your headlight throw light down the road; you will now have possibly the WORST visibility possible other than not having headlights at all... it may look bright when facing your car but it will have extremely dissapointing coverage and beam pattern when looking from behind the wheel.
in a projector, the light source, lens, ellipsoidal reflector, and cutoff shield, all have to be in perfect alightment for the light operate correctly, move any of those components and the light loses its function (except for a movable shield in a bi-xenon application). the first anology that comes to mind of using a projector lens with a normal reflector bowl is like mounting a 19" tire on a 18" wheel... no matter how you want it to work, it just won't.
you have basically done 50%-75% of the work to do a correct projector retrofit. abandon this misguided idea and do it correctly with the entire projector.
