Do you live in an old house? Are the duplex receptacles two-pole or
three-pole? With modern wiring there should be a bare copper wire entering
the box and attaching to the box at the rear. This would be uninsulated and
therefore it looks different than the other two wires, and it might end at
the box ground screw.

If you have no ground wire, I would consider asking an electrician to do
the work, in the interest of safety.

I removed a light fixture (flourescent) and am replacing with
incandescent light. The instructions in the box seem very simple.
Only thing is...the bare (or green) ground supply wire they refer to
does not exist.

From my ceiling (supply wire) I have a black and white - that's it.

From my fixture, I have a black, white, and bare wire (screwed to the
base of the entire contraption.

So, what am I suppose to do? Thank you, in advance to anyone who
answers me.
