Well, Bratton's instructions are wrong. Here's how filaments work:
Longer filament = higher resistance = lower current = less light (dim)
Shorter filament = lower resistance = higher current = more light (bright)
The filaments are equidistant (1/16") from the center plane that intersects the base contacts, so the original headlight reflector opening is elevated to compensate for this, causing the brighter filament to be adjusted along the parabolic axis.

So install the bulbs with the longer filament on top and make sure it's the one that illuminates with the light switch in dim position. If not, either spin your (repro) reflector 180 degrees or swap wires at the conduit socket.
Back to bulb spinning.
