As for instrument/gage lights, I guess the difference between the 194, 161, and 74 are the brightness? I'm planning on putting colored bulbs in place of some clear ones, and hence, the question. Also, how easy is it to change the bulbs for the gages? Any known resources, other than local auto parts stores, for these colored bulbs? I've found a couple, but where I live, they're not in vast quantities... Thanks...

The sizes vary slightly, but it's the brightness that's the difference.

The bulbs shouldn'tbe too bad to change, just take the guage cluster apart.
