'59 Headlight Question

[Tod59]

Hey Guys,

I'm restoring my '59 headlight buckets (cleaning, painting and new adjusters).....

Question: Is the 3 prong headlight placed on the "outside" headlight bucket? Is the 3 prong headlight the "regular" light?

Essentially, the 3 prong light is the "regular" headlight and the 2 prong headlight is the inside of the bucket "bright" light (combined with the regular outside headlight)?

Hope this makes sense.
Thanks
Tod
