Alright, I did some searching around. You are right about the vanity mirror not being the 194/168 bulb.
They have to be a #74 type bulb. Online comparing the 168/194 to the 74, the 168/194 has a larger base and top to it. The 74 is not as round at the top and a small base.
I know because the HVAC panel uses a 168/194, and gauge cluster uses a 74 as I found taking the bulbs out 2 days ago. I just ordered both of those bulbs in red incandesant and red LED types to find out which one will be brighter and appear more red.
194/168
74
After alot of searching, it appears Polarg does not make a 74 bulbs. You will have to find anothing brand for the 74. I think I may leave the vanity mirror bulbs stock. I think aftermarket would blind someone trying to look in the mirror.
