Strong winds damaged one of my post lamps so I am replacing it. It comes with three wires: black, white, and bare. The top of my column however only has two black wires coming out of it. How should I wire it up?

FWIW all the lighting in my yard is controlled by a single physical dial-type timer that is plugged into an outlet.

    Assuming its a metal post, the bare wire would be connected to the post. Commented Nov 27, 2023 at 3:40

The bare wire is safety ground.

Most lamps, especially LED lamps, don't care a lot about which side is connected to hot and which to neutral, which is why they're both black -- it saved the manufacturer a fraction of a cent per lamp. Hook either one to black and the other to white.
