Fun find of the evening! It's pretty well known that Suzuka 1997 was the first ever 'race' test of Good Years rain tires for the Winston Cup cars - with some teams also throwing on home made windshield wipers and brake lights to make it safely through practice and qualifying. It never occurred to me that some teams didn't have the time or man power to remove some of these additions prior to the race.
I had noted that some cars I saw during the race broadcast seemed to be lacking the normal FORD, CHEVY and PONTIAC emblems on their rear bumpers but just chalked it up to not having manufacturers support for this exhibition race. BUT - as seen is this wonderfully clear race image I found on Twitter - those few cars that I saw as missing their rear emblem most likely still all had their makeshift brake lights installed!
Note the rear of Kenny Wallace's white #72 and Lance Hooper's #1.
How cool is that?!
