Ah, Dume - I got sucked in by immediate gratification. Went to the library to return a couple and grab a couple and there it was. Shining in the distance like a Hula Popper on an evening pond rivets a bass. O'Reilly's.... All lit up and pulling me like a tractor beam since I called them yesterday and knew they carried the one I wanted.
So they had the one I wanted in stock - the Sylvania updated version of their 1156 entry. The old one is festooned all 360 degrees with multiple cheaper LEDs. I figured from the new lollipop form factor and orientation of the pins it would suit the Supra's 3rd brake light format perfectly. Half the LED's point directly rearward out the red lense and the other half bounce off the reflector - no wasted side LEDs. In my garage a few minutes ago it was an impressive output.
So, now that I've ignored your recommendation for the 3rd brake light - what are you using in the tail lights - brake and running? I don't even know what's in there yet as my eBay'd 1988 owner's manual will be here next week...
I sent you my full list on one of your posts when you were traveling, but I don't remember which one.
But from amazon in January 2020 here you go:
