Yeah, I'm sure the assembly workers didn't match headlamp manufacturers, but that car is my 14th RR and the 1st Tung-Sols I've seen on one.
All have been original cars, mostly St.Louis with a Lynch & L.A. in the mix. All matching-set GEs until this car.
I remember the Tung-Sol name from long ago as an parts-store supplier.
It could be that with the significant sales (and therefore build) increases of '68 - '69, Chrysler was sourcing headlamps anywhere they could.
An original car (survivor) would be considered as such with a replacement bulb, the only way to reduce the doubt is to look at the date code.
I did a quick search but couldn’t find what my mind recalls reading. Some time back I recall reading some speculation Tung Sol may have been more prevalent in the LA builds, though still not with any regularity. In my case it was research related to road lamps, but with my build being an AAR (all built in Hamtramck) I couldn’t use the Tung Sol lamps I had and was forced to find some GE’s
