[Tigers] rear light bulbs

[Rollright at aol.com]

Hello,
 
I came upon some brighter stop/tail bulbs called 1157 HP on Ebay. Still  
incandescent but quite bright.
So, I thought, that's the stop tail, what about the 1156 flasher  lamps?  I 
looked and looked and there doesn't seem to be any labeled 1156  HP.
 
I really don't want to use LED's or halogen. Does anybody know of a  
plug-in upgrade  for both of the rear bulbs that I can get at the local  AutoZone 
or NAPA?  Part numbers?
 
Thanks in advance,
