[TOMT] Those light up pins id see at the gas station convenience stores

I think in the 2000s and early 2010s i would always see these light up pins I believe, I cant remember if they were enamel pins or regular button pins but i know that they light up, and some frequent designs would be hearts or skulls or something with the American flag design.

I’d like to know what the name of those are, and if anyone has any images of them, i cant find any images of what i remember they looked like. At the gas station convenience store there would always be this clear box display by the register with many pins and each pin would have one or three lights that would flash around, usually red lights i think. If anyone could help with the names of those specific pins or the brand names or even better, some images! That would be great, thanks!
