Interesting Rare Third Brake Light

These are really neat, but usually quite expensive. You connect a vacuum line to a vacuum switch which works off the brake pedal, then to the intake manifold. When the pedal is pushed the vacuum is sent back to the light, which had a vacuum motor to swing the light left and right. I have one that I'll connect to my Model A someday. I'm not sure who made these old lights, but they are often called "Studebaker Wig-Wag".

I still like Tom's Studebaker light better, but not $400 better.

Those are pretty cool....
I’ve not seen them before!

I didn't realize they moved so quickly. I may have to install a restrictor to slow mine down when I install it.

I suppose if you fed it with 12v, it might shake the car like an out of balance washing machine during spin cycle!
