What years were T-3 headlights used in Chrysler cars, if ever?

I had a buddy in Pennsylvania that had me searching for functional GE T-3 headlights for years out here when I was junking for parts for various cars he (we?) were prepping for the annual trip to Carlisle back in the 80s and 90s. The T-3s were immensely popular with the mid-50s Chevy guys as being OE for them.  I'm guessing that by the mid-to-late 60s that wasn't the case for the muscle stuff, but I really don't know.  The reason I'm asking is that he's gone now (lost him last Christmas) and I still have a few here.

I think they were only used in GM cars.

T3 headlights were made by Guide (a GM owned subsidiary).

Makes sense Gentlemen.  Thank you.
