They switched from 9012 to 9005. Can’t remember what year, I have 2014 projectors in my truck, they are 9012 as well.
Looks like it was in extremely late 2015 (last 2 weeks). That's when the headlights switch to new part numbers (not just the revision letters at the end). I really hope the replacement I just bought from the For Sale forum here is the 68093221AD and not the 68324933AB. I hadn't realized there was a switch. I'll find out when it arrives today. :/
