Headlight bulb filaments - which is which?

[Sparky]

I recently picked up a pair of Model A headlight assemblies to replace my current sealed beam units. I had to rewire the sockets, and the bulbs were missing so I ordered a set from a parts supplier. The bulbs I got have two filaments; one is straight and the other is bent in a V-shape. Which is high beam and which is low? And the low beam filament goes on top, correct?
