Technical Help Identifying Tail Lights

What are these tail lights from that are mounted on this '38 Chevy? I initially thought Buick or Pontiac, but the lenses look square. I checked The Mother Of All Tail Lights Threads, but I didn't find anything. 

 

50 Pontiac

 

Thanks, alchemy!

 

OP picture shows the lens to have squared-ish edge, don't think they are Pontiac.

 

Hmm,,

 

Pontiac 1952,51,49,48

 

Yeah, I don't think those are Pontiac either... Probably aftermarket used on trucks, trailers and early kit cars.

 

is it just me... does the lense look like it has a sloppy fit in the bezel? Maybe the bezel is something different like a domelight bezel? Just thinkin' aloud...

 

Yep i was thinking truck or trailer. A bit utillity looking.

Probably a Pontiac light with a different lense

 

'29 Gizmo, that's the shape of the lenses. The picture doesn't show it clearly on the driver side, but you can see it on the passenger side light.
