What bulbs for dash?

FYI, I decided to do a little resurch on the bulbs and for my car (76 Duster) the original bulbs are 158 so here's what can fit.
#158 14v .24A 3.36W
#194 14v .27A 3.78W
#168 14v .357A 5.0W
Anyone use the 168 and if so do they get to hot?
There are only 3 bulbs that actually need to be brighter and they are not tightly enclosed so I am hoping for the best and am going for the 168's as they should provide the most light and maybe I wont have to turn them all the way up.
