I've read that General Electric headlamps were the original, correct headlamps for pre-1970 B-Bodies. Westinghouse headlamps seem to have entered the scene starting in 1970.
A quick look at the current offerings at the various auto parts house reveals the following available brands: Sylvania, EiKO, Wagner, and Philips.
So I guess it's good luck for anyone who wants Genuine made in the USA General Electric headlamps on their classic B-body Mopar.
Moving on, let me post what I believe to be the two remaining original headlamps from my St. Louis built 1969 Road Runner - SPD 9/10/68
Part numbers #4001(high) and #4002(low) are the correct part numbers.
Date code? April or August 1968? Anyone?
When I was cleaning up my two headlamps, the ink stamp from the 4002 bulb almost completely washed off. As a result, I messed up and ordered a P/N #4000 which supersedes #4002. Headlamp #4000 is marketed as a Plus25 bulb claimed by General Electric to provide 30% brighter whiter light for better visibility. I'm to understand this due to the fluting of the glass lens. For your viewing pleasure I've posted a side-by-side comparison below comparing the lens fluting.
Ebay score came in today. Now let's take a closer look ->
