D2R bulbs are for bi-xenon projectors (hi and lo beam) D2S are for single lo beam projectors. Both of these bulbs are for HID projectors.
As stated, if using the H7 Halogen projector, then an H7 conversion kit is needed OR an H7 adapter for a D2S bulb.
You'll also need to correct ballasts, conversion or true HID.

Hey there.. I am trying understand all that too.. so now I do have in my car stock HID... so I assume I will need to buy D2S bulbs..[/quote]
Yes, you'd use D2S bulbs, as you have HID projectors.

but if someone has H7 halogen projectors.. hows that work? don't they need special lenses? why they can just buy all the KIT and thats it? why my car has lenses.. and other cars just need H7 conversion kit without lanses? isn't that going blind others? [/quote]
The name *conversion kit* can be a bit confusing. The conversion is really just the bulb. The bulb is made with an H7 type base so it will fit into H7 halogen projectors. This is called a *re-based* bulb. A D2S bulb's base will only fit a true HID projector bowl. Now, there are H7 adpapterts to use a D2S bulb in an H7 projector...case in point, Valeo H7 projectors are said to be excellent for HID use, despite being a halogen projector. But i have never seen any other D2S adpaters, other than for an H7.
As for the projectors themselves. HID projectors are optimised to be used with HID bulbs, and will have different bowls and lenses than their Halogen counterparts. Ideally, when using an HID system, an HID projector is much prefered. But since ppl cannot always afford a true HID retrotfit (<< more on this in a minute) the demand for aftermarket HID kits that fit into their current halogen projectors was created...and in our case, the Mz3 halogen projectors aren't all that horrible for HID use...better than most, but not super duper either.
Typically, unless the aiming adjustments are messed up, using HID bulbs in a halogen projector will not blind oncoming traffic...using them in reflector based lamps (like our high beams) then yes, they would be blinding.
A retrofit, is when you take a complete HID projector (bowl and lens) from another car and fit it in place of a halogen projector or into a reflector lens. This can be a daunting task, as building a proper mount to be able to aim it properly and have it look good is not always easy.

Also is there any chance to make my stock HID as a bi-xenon? or it is just not worth?
thank U much.

I have no idea if that would even be possible. A bi-xenon lens usues 2 cutoff sheilds, low beam and high beam and a solenoid or something to switch between them. adding this to a single projector lens would probably not be worth it, compared to retrofitting an actual bi-xenon projector.
For more info on HID's, i've found this site very helpfull. I'm still new to HIDs but i reference this site alot.
