Trying to figure out what this driving light kit is worth. I've found used individual lights and Model 500, but can't find anything that is new old stock for Model A per the stamp on the light, or Model 61 per the label on the box. Also, does the switch in the photo belong to the kit or was it sold separately?
The Model A is their own model designation, nothing to do with a Ford Model A. And I’d doubt the 1937 means it was approved in that year either. Probably a code number for some state law or something.
Well your right on these have nothing to do with Model A, but your definitely wrong on the 1937 approved that's not some sort of state law. You'll see the 1937 Penna Approved on most of your higher quality fog lights such as Appletons and Arrow
