I assume the rear doors puddle lights you are referring to are for the red lights (a little higher up on the rear doors)? My rear doors (I don't have the premium light package) don't have the holes/cutouts (I can see the spot in the plastic where they would be) on the bottom of the rear doors (on the plastic below the speakers).
The red lights on the edge of the doors aren't the puddle lights. I've heard them called "emergency lights" although that doesn't make a lot of sense to me. Puddle lights are white and on the bottoms of the doors. Interestingly I went out to my car just now (85D configured in March 2015, tech package but no premium lighting) and I only have puddle lights on the front doors but not the rears, just like you. I wonder what's behind those punch-outs in the bottom of the doors...like if there's wiring for the lights there. I don't recall seeing any discussion of this, but I'm not brave enough to rip open a rear door to find out.
pete8314, thanks for all your efforts on this. I intend to order some bulbs once I figure out which make sense for my car.
