Question for people who HAVE HID'S
When you converted to a H4 style headlight housing did you use a housing with a reflector in front of the HID bulb or a housing without a reflector inside? How does the HID kit look either way? Thanks.

i used HELLA e codes that are H4 conversions without shields, i then used an H4 to D2S adapter to fit my HID's. i really dig the beam pattern of the e codes. if you just add HID's into any H4 type housing the light will scatter like crazy and will look kinda crappy.

The Hella E codes are really the only option for the maximum performance of your HID's. Anything will cause crazy light scatter and won't really make anything better.

i got mine from here. i don't see what you mean by "anything will make the light scatter". i get a nice sharp cut off, almost like projectors. yea their site is really scattered, but they have pretty fast shipping.

Lotta mis-information here.
First a little background.
Now we are talking about true HID bulbs, not the blue coated Halogen bulbs sold as Xenon or Krypton or the like. HID bulbs require High voltage (typically around 20,000 volts) and are run on transformers/power supplies for automotive use, where as cheap as blue colored Halogen/Xenon bulbs plug right in as a replacement for the stock bulb with no power supply/transformer.
HID lights come with two different style bulbs, D2S and D2R (well there is D2C as well, but those are not applicable for headlights).
Most (99%) of the true HID H4 kits come with a D2S bulb. This means that they should be in a lens/housing that has fluted glass, that the majority of the light goes through a lens. Now if you had D2R bulbs, they are designed for the relfector to do most of the balancing of the light.
Mixing these up will result in major light scatter. Without any sort of clear cut off or definition to the light coming out of the housing. (this effect is what Danial Stern with his lighting page calls out saying that HID lights should not be used as a retrofit application- he uses this too sell is Ciba E code lenses and Halogen bulbs). For example, using a D2S, bulb in a housing that has a clear unfluted lens is bad, as would be using a D2R bulb in a housing with a fluted lens.
Now, the 7x6 (200mm) replacement housing that fits our cars, comes as either a Reflector type or a Lens type. In addition there is a hybrid of the two that has a bulb shield and a fluted lens and a second type that uses focused magnifying lens (both of which frankly should never be used in any car- as everything about both of them fails to focus and direct the light).
So it is important to use the correct housing with the correct bulb type.
Also it should be noted that for a H4 housing to work correct, there needs to be a bulb shield on the tip of the bulb or in the housing (but not both) as to prevent the blinding of other drivers with the direct top output of the bulb.
Hope this helps fill in some of the misconceptions in this thread.
