So to double check, the rear turn signals and outer brake lamps use the same bulb type on your car?!?!?

On my car they are two totally different bulbs with two completely different bases. It is physically impossible to insert the same bulbs into both (I tried). The turn signals are a larger P21 bulb whereas the outer brake lights are about half the size and H21 bulbs.

I'm starting to think this may be a subtle difference for the F32. Wish I took a picture of the bulb assembly last night.

I followed the links several times, way to many options. Do you have the exact Bimmian part numbers you ordered?
