Even putting HID's into halogen projectors messes with the cutoff. The change is not nearly as bad as what happens with a HID in a halogen reflector housing, but the projector typically loses the straight line cutoff it has with a halogen. If the HID bulb uses a halogen bulb code then it and the projector are not a proper HID design. For example, H code or 90XX series bulbs are halogen designs so the HID bulbs with those codes are "retrofits". D code bulbs like D1S, D2S, D2R are HID original designs so the corresponding projector housing was actually designed for them and not for a halogen.
Theretrofitsource above sells HID kits with HID projectors, using true HID bulbs and ballast's and results that offer true HID beam projection/cutoffs......the kit I have is as good as the factory HIDs I have in my other cars....they are that good

I dont know if thats always the case though.
About 7 years ago I bought replacement light housings for the 96 dodge truck I have. they are projectors (low beam) and came with halogens for high and low but stated they were hid compatible. I replaced the halogens with 55w hid lights and the cutoff line is perfect with the indent for left hand drive vehicles. been using them ever since. I bought everything on ebay then. I did try the 35w hids but the ones I bought were not all that bright.

You are correct!
I have said this before but the same theme keeps coming up about the incompatability of all halogen projectors with HID bulbs...NOT TRUE. There are some OEM factory halogen projector headlights that are HID approved by the manufacturer. This scenario is the case with my 2008 Chrysler 300 that came new from the factory with Halogen projectors....This factory lense is the exact same lense that is used by Chrysler for their OEM factory HID option on this model car...there is no difference from the FACTORY between the 2 headights (halogen or HID's). I replaced the factory halogen bulb with a true HID system (McCulloch-Made in Germany) and the difference in the beams before and after the switch was EXACTLY the same using the HID's in the low beam versus the halogens. 8 years out now I am still using the these same HID's...never have had to replace the bulbs or the ballasts...quality system and were pricey back in 08 at $279 for the components....I didn't respond to the comment since I am tired of some beating the same incorrect statements over and over............

I'd like to see a link to these halogen/HID dual use projectors that came in a 2008 car, since they didn't make them. Actually, it's pointless to ask so I'll just prove you are wrong with a couple of Chrylser part numbers for each type of housing used on 2008 Chyrsler 300's.
04806165AJ - left halogen projector headlamp, black bezel
57010759AA - left HID projector headlamp, black bezel
There are 14 different numbers in total, but these 2 are enough to prove the point.
I am willing to bet money there will be some change in beam pattern on EVERY HID retrofit into a Halogen projector, so my comment stands. In some cases, it might be fairly minor and in other cases it might be quite obvious, but in every case there will be some change in the light spread or hot spot areas present in the beam from the light.

The part numbers are different because the HID projector houses some of the components of the HID system versus the Halogen projector which is just the lense/projector...the lenses are the same....
#2 do you own a Chrysler 300 and have you done the conversion I have from the OEM halogen projector to the HID's in the same lense housing comparing the beam pattern before and after carefully against a flat wall or garage? My guess is NO. When you have done what I have done we can talk. Until then I am not really interested in anything you have to say...DONE!

A complete projector is MUCH more than the lens. The reflector bowl and a cutoff shield are also very important pieces in how the whole unit works.
It's not like each are a completely different design. The differences are fairly minor and you might not even notice just looking at the units from the outside without really taking a good look. Still, a HID projector will almost always have a different reflector bowl shape and take a different bulb. It will also often has a different cutoff shield.
Here is an example of projectors from the same car using each bulb type.
Same thing in these examples too. The bowl, cutoff shield and bulb used are different.
In the middle link that there is a picture of the HID and halogen projectors with a HID bulb in the halogen projector. Notice how the halogen projector with the HID bulb has a much hot spot in the middle with the light less spread out. This puts more glare into oncoming traffic vs the HID projector where the beam is wider spreading the brighter HID light out more evenly. This show show it's not just the beam pattern that is important, but also how the light is dispersed below the cutoff line.
Since you're so sure of yourself, post pictures of the cutoff shield and bowls of both projector types in your "identical" Chrysler projector headlights showing how the WHOLE projector unit is identical. Saying the lens is the same in no way proves the halogen and HID projectors are the same because the lens is only one piece of the projector.

I forgot yesterday but the Chysler 300 halogen projector uses a 9005 bulb and the HID projector uses a D1S bulb. One doesn't fit where the other one is, so can you explain how that works? I bet you used a 9005 HID retrofit kit and not a D1S bulb.

By now it should be quite clear that the actual projector housings are different and they are not interchangeable. It should also be clear that your attitude about the subject far outreaches your actual knowledge on the subject.
