i just had this problem in my gen 2 theirs 2 lights, one under the + and - for sst mode aqnd one under the p,n,r etc. but just take out the center piece that goes all the way around the shifter than the little square covering the still covers the lights, they look difficult but once you do it they really are a breeze to take off. and i just went to my local advanced auto parts and got some from there, i cant remember the number but we just matched em eye to eye from some off the rack and they worked fine. but if you really want the ford parts number i have that also. and if you have big fingers they will be a pain in the a** to get out. i lost one of the bulbs when i first took them out cause it flew out my hand. your best bet is to get a pair of tweezers, and gentle grasp em and wiggle it in and back and forth motion pulling up and theyll pop right out. take your time with the trim pieces and bulbs and its super easy.
It looked like a 191 or 192.
