Is this a Datsun Taillight?

It looks pretty cool, I like the design with the circle bleeding off into

a chrom stip through the center.

Says it's made by Koito and part number is S10576.

Looks to me to be a Toyota Corona, Crown or Cresida style though.

Yeah, I can't quite visualize the entire car from the light itself, but I'm thinking late '60s Corona.

Nah, those would be different. No circle, wider, and not as tall. I had one.
