If you happen to have a VOM (volt,ohm, milliameter) you could set it on "OHMS" then touch one test probe to the center contact in the light bulb socket and touch the bare ends of the wire with the other probe. The wire that shows continuity would be the "Line" wire and would go to the black conductor at the source.
