The Ford Barn

While looking for some distributor parts I came across this gadget. It's about an inch high and about 2" by 4" at the mounting flange. It's too light to be a step up transformer. It was made in Denver, Colorado. I've never seen anything like it, and wonder how it works or was wired into the system. It has two short wires coming out that were cut off and have no terminals.

The only thing I can think of is it might be a low ohm resistor that is wired between battery voltage and the field windings to increase the generator output.

Interesting that it says for Ford cars. Since it seems to be an aftermarket thing that could be used for any car, why specify Fords?
Anyone have any information on it? Thanks

If you take those two small screws out will the cover come off??

Here's one with three wires. I found some reference to cars with magnetos......like "Ts". DD

Thanks Dave. So this gadget turns off one headlamp and lets all the magneto power go to the other headlight. Why they want to turn off the left headlight is a mystery, as it would be safer to light the left than the right.

Right side illuminates the edge of the road?
I see your point about the left side safer for cars approaching from the opposite direction.

Probably because the magneto would put out too much power for just one lamp, and it would burn out.
Even running a 6 volt car on an 8 volt battery greatly shortens bulb life.
