Thanks for the good info, 30. Not quite a plug and play solution, but I see how it can work. It removes the external adjustment in favor of a fixed-focus design like the later 30's Fords using the flanged bulbs. The purpose of the manual focus was to throw the original 21 CP beam as far forward as possible. As Brent in TN points out, precise focus becomes less relevant with higher intensity bulbs.

The importance of proper low-beam angle and intensity becomes apparent when you encounter dense fog. Also I wonder how the different color temperatures (light frequencies) affect the amount of light reflected back into your eyes in fog.
