Buddy, your questions are making me dizzy.

In short -

HID (D2S) for your dipped beams.
Halogen (H7) silverstar for your mains.

 

your car uses a H7 bulb for low beam.. in order to run the "bi-xenon" you need to use a H4 bulb.. so no you can't run the "dual beam" as you would like to call it.. so 1) make sure you have projector headlights (found on 99.5+ A4's, one piece housings, or go find a set online, depo, helix, valeo) and then 2) get the single beam H7 kit from vvme.com ... if you would read on their website how everything is broken down all of your questions would be answered... just sayin

 

How hard is the 99.5 headlights to put in and are they direct fit?
thanks again

 

You'll need to trim the fenders, just a thin strip of metal - it'll be obvious when the old units are removed.

You'll also need '99.5 connectors, easy to get from a junkyard.
The wire colors are the same as on your current set-up, so it's just a question of cutting your old connector off, and fitting the new one.

There are quite a few write-ups on the conversion, just do a general search.

I can also supply the connectors if you don't feel like rooting around in a junkyard.

 

Ok thank you!
Do the 99.5 also run h7 bulbs?

 

Yes, they do.

 

Hey man just to clarify a few things, whats the difference between the H7 HID's and the D2S HID's? because the stock bulbs are H7's in the low beams. So is there a reason you would want the D2S instead of the H7 HID kit?

 

So since I have fog lights in my headlights now, will I have them still in the headlights when getting the 99.5 headlight, or will I not have them?
Thanks!

 

You'll lose them. The facelifted cars with the one-piece headlights have the fogs down low. You can buy them and retrofit them to your car - that's what I did (see center pic in my sig).

 

Ok, but what if I ran the 2 piece projector? Can't really see yours, but looks good!
