Default HID to halogen swap

Greetings folks,

So the GFs used Mazda 3i left headlight was jacked. I mistakenlyish bought what I thought was the right one in rockauto. Turns out the $830 version was the right one. Well neither one of us have that kind of cash for a headlight. So my question is this. How do I go about converting from the OEM HID with auto adjust to halogen manual adjust?

I looked around bit didn't see a detailed answer. So if this had been covered please point me in the right direction.

Super thankful for:
1) not poking fun at my potentially dumb questions.
2) saving me from finding a $850 replacement.
3) helping me be my GFs hero.

OEM all foggy

Busted reflector

OEM part number

What I bought.

I know how you all feel about resurecting old threads, but I feel like we did not get an answer here if it worked and how it was done and I don't like starting redundant threads. Our daughters 2010 Mazda 3 HID auto leveling headlights were both full of water and the ballasts were flooded and obviously broke, the dealer wants $1,400 per headlight and the Interwebs want $1,000 each, so I went out and bought two used basic model Halogens at the junkyard with no running lights, as simple as it gets, and I have succesfully adopted the HID wiring harness to them

Turns Signal / Parking Light is exactly the same and just snaps right in - no changes needed
Low Bean - I cut off the HID plug that ran to the ballast and soldered the Halogen low beam plug to it, works great
High Beam - I don't know how to get these working hence the post
Running Lights - her car per the VIN does not have running lights (although the current HID assemblies have running lights and running lights wiring harness in them but they don't work, someone must have swapped the original ones out at some point and installed these in) so I am not worrying about those, but for extra credit if you could tell me if there is some way to make the running lights come one, enable them in the computer or what ever that would be great
