What the OP's showing is definitely not a blackout or CD pattern.
Those bulbs were literally "blacked out" with just a small slit open. They were more to feel around and be seen within 50 feet.
These are half chromed, allow their full output downward, would be too reflective to oncoming light, and would get flagged by CD.
I'm pretty sure it's a fog pattern bulb.
I don't know why someone would put them on a show car, though, as that is not what Chrysler would have factory equipped.
