Most of those bulbs can be found listed at
http://lighting.mbz.org/tech/info/signal_bulbs/ .
The 2357 is the brightest one I've been able to find, none of my local vendors
seem to even have a listing for the 1297K or 1297NAK.
I couldn't find any info on the 1174.
I believe the long life bulbs draw slightly more power and have about the same
brightness as the normal bulbs, but I'm not sure.
