Hot Rods Vintage clear lense accessory lights I’d help

I have two vintage accessory lights I would like some help with some information on. The smaller one is stamped Hall Lamp on the back stand. It was on the back of a 47 Ford super deluxe I saved awhile back. The other is stamped FoMoCo on the front tab.
Any information on these?

 

Cant help with what they came on , but do like the glass pattern on the sm one.

 

The smaller one looks like a "Unity" accessory light Ford branded.

 

i love the pattern on it as well. It’s going on my 46 sedan.

 

Thanks for the information!

 

CM Hall was a light manufacturer that made many of the lights for big shot cars like packards etc. Not sure when they died off, late depression, or during the war would be my guess

 

CM Hall also made headlights and "work lights" (mounted on rear fenders, facing backwards) for tractors.

 

Early back-up lights....

 

That small one resembles the “running” light that was popular to mount on your car in the 50’s somewhere on the front grill.
