SO.... I indeed have this same question.... I have not looked at this yet. I found this thread after a part number search on the light.
Glad I don't have to bug Rod now that I know the history of the HID install prior to him....

|Rod in NC||thenorm, does your halogen bulb work on hibeam? Thats my goal. My bi-xenon do work ok hi and low beam. -Rod|

the Mach HID projector is bi-xenon, but it is not wired that way.
to get mine to work proper as bi-xenon i had to jump a wire.

|Rod in NC||Rabitccc, seeing your post, I'm now wondering if my headlights themselves are functioning properly. This morning I pulled out the DEPO headlight. I pulled back a bunch of loom off the headlight and main harness...I see no splicing. The plug going into the back of the headlight looks like oem Ford (had 'FED' on the side of the plug) and not a VW plug with yellow wires. So my bi-xenon work, my turn signals work and my little parking light works. Just not my halogen. I think I will leave as is and not mess with it unless any other ideas. I don't feel like tearing into the back of the headlight assy, but this still has my curiosity. I just ordered a factory service manual and wiring diagrams off Ebay...when those show up I will confirm the wires in the stock connector. -Rod|

|Rabbitccc||Well dang. Sorry about my incorrect post. The whole time I've been running my Machs in my old car and I had it wired wrong. I knew they were supposed to be bi-xenon, but I thought they just didn't use them. Here this whole time it was my Jerry rigged wiring job. Good to know.|

Here's the diagrams I used for my car.

|Rod in NC||Perfect! Thanks for the info and pics, guys. I like the idea of having the halogen kick on for high beams only. Yes, my DEPO lights are the chrome style. Knowing that now should help me find some pin-out diagrams of the wires and connect. Looking forward to pulling off the headlight and digging into the wiring to decode how to get that bulb to kick on. Thanks again. -Rod|

Here's how mine work.
Low beam with middle HID's only:
High beam with both lights on:
The center halogen don't add much light by themselves but I find they do add a yellower ting to the light output versus the white/blue of the HID's. This helps you to see the edge of the road better when there are no lines and makes it easier to see small details as you approach them.

The Mach HID is bi-xenon. When the "brights" are selected the mechanical cutoff shield is physically moved out of the way, allowing a full circle of illumination. At the same time, the high beam halogen lights, the inboard ones, should also come on. There is something wrong with the wiring if they don't. That said, the halogen really don't so very much in addition to the high-beam HID.
Use this link to figure out what's going on with the wiring:

If they look like these just chrome. They are DEPO versions of the SVT Mach HIDs. On the SVT Mach HIDs the inner bulb your probably questioning is the high beams. The center actual projector is the actual Low beam HID. It sounds like this guy put in his own bi-xenon projector that does both low and high. For whatever reason.
