Christmas Window Flashers

No not that kind of flasher!

I'm looking for somewhere that sells those old school flashing light Christmas decorations that people hang in their windows. I have trouble describing them - they are often circular and basically consist of flashing lights in an abstract design.

I see a lot of them in the neighborhoods around St Clair West. A lot seem to have incandescent bulbs, so maybe they're out of production now, but my partner wants one for Christmas haha. Any leads would be helpful!
