Electrical Question from Mike about Electrical Wiring


Question: This house was built in 1947. I want to replace some outside lamps: the new lamps have insulated black and white wires and a bare copper wire.
The wiring coming out of the wall looks like two black insulated wires and no copper or bare wires. No third wire at all. No lamp mounting base either; the house wire just comes out of a drilled hole in the wall. What’s my next step?
