2013-2014 Focus ST Bulb Sizes/Types

Looked on the forum and I didnt see this list, so here it is. If it's already posted up on here I apologize in advance. But this list helps people who have a hate for halogen bulbs and like changing everything to LEDs or would like to change out the headlights. I will do my best to keep updated with interchangeable bulbs too.

Front Lights:

Low beam - H11 (ST1/2), D8S (ST3)
High beam - H1 (ST1/2), H7 (ST3)
Fog - H11 (ST1/2/3)
Parking - 168NA (ST1/2), LED DRLs (ST3)
Sidemarker - 168NA (ST1/2)
Turn signal - 7440 (ST1/2), PY21W/7507 (ST3)
Cornering lights - PSX24W (ST3 Only?)

Rear Lights (ST1/2/3):

Back up - 921/T10/194
Sidemarker - 3757A / 3157 / 3157-SCK
Turn signal - 3757A / 3157 / 3157-SCK
Tail lights - 3157 / 3157-SCK

Interior Lights:

Trunk/Cargo Area - 2825 (ALL)
Vanity Mirror Lights - 28mm Fuse type

Currently working on finding out what the interior lights are. I would assume those are T10/194/168/etc as that is pretty standard protocol.

Sidemarker - 168NA (ST1/2)

Are the side marker lights the bulbs inside the exterior rear view mirrors?

Interior Bulbs in foot wells and dome lights are 194/168in my ST2.

I know the bulbs the shine on the ground are 194... cuz i swapped those out the other day. the yellow turn signals should be as well as that is only bulb size i know that would fit in there. its kinda hard to reach at behind the mirror though.

turn signals front and rear have to be amber on ST3. ST1 & ST2 can be clear in the front but have to be amber for the rear. the rest can be clear

What bulbs are the puddle lights in the mirrors? Did I miss that?
194, T10 same thing.

Now if someone would just cross-reference this list with LED equivalents and list a single location where I could buy the entire lot at once, I would be ecstatic.
depends how much you want to pay.

Looking to find out the spectrum range on the HID's. I want to change the fogs to the same spectrum ie 4000k or 4100k as the HID's. I am continuing my search but thought i should just ask. I might get a response faster than my searching.

Cheers
