Headlamp #'s in the Glass
 

This is from a bud, what's the 2 mean on the single power beam headlamp, 1's & 2's are on the 4 lamp set up, 2's being the headlamp, 1 being the high ram, I know of a date code stamped on the back of the bulb itself, what does the 2 mean ???

Same thing it means on the four light system, the bulb has two filaments.

Thank you Sir.

I guess he's was asking the numbers above the 2. I misunderstood him. B 105

Most likely a mold number, but don't take it as gospel.

There's 2 old guys at the Packard Prov grounds swap that sell headlamps, now I have something to chat a about, lol. Thanks.
