Tail Lights (What is it from)

I just Frenched in these on SWMBO's 57 Chevy Truck. But it don't know what they came off of. Anyone have any ideas?
Picked them up at a swap meet from a bucket of other lights.
Thanks for the help.

Cool Thanks.

 

Good job on those lights. First time I've seen 'em used in a rod. They lood pretty good, kinda like a squared off version of a '50 Poncho light.

 

There's a 47 Ford coupe on eBay right now with the same tail lights.

 

yup 65 chevy...........i got one haha

 

There is a 65 SS out in the woods somewhere on this board with 6 of em.
