I think you are correct about the fog lamps up through at least 1954 being Guide (the link I gave above is for '54). The '54 photo above also shows a spotlight that looks more like a Unity style lamp.

that's funny because my 1950 Passenger car accessory installtion manual show's the same thing,a unity light but defetley take's a Guide s-18 w/ mirror.
