I have what should be a simple sealed beam question.
Which of the three prongs is the ground?

You should be able to see through the glass and see which 2 filament ends go to a single contact. If that isn't possible, then I'd use a battery charger and connect until you determine which one is ground. If I find my bulb I'll take a look.

Just found my bulb, and looking at your picture, the terminal on the far left is ground.
