Lorraine, Thompson, and the above shown Unity are all the windshield post mounted spotlights that I can think of for now. An interesting note
about the Unity Sportlight (or "Sportlite" as it was spelled on the light itself) was Ford recommended and sold/installed by Ford dealers. However, the name Ford was not shown on the light. Yet, the Chevrolet
sold/installed Unity Sportlite came with the name "Chevrolet" on it!
The Unity Sportlite came in three models: Junior with 5 & 1/2 inch lens
(The Ford recommended model), Standard with 6 inch lens and the De Luxe with 6 & 1/2 inch lens.
The Lorraine was more of a high-end car spotlight usually mounted on
Lincolns, Cadillacs, Duesenburgs, etc. Of the Lorraine lights that I have
all have the same size lenses, but with varying degrees of chrome,nickle
or painted parts. Which I guess signified different models and cost.
Information on spotlights and accessory fog/driving lights of the Model-A era is almost nonexistent and with what info I do have. I have deduced from original sales ads, catalogs and pictures of the era.
