How to wire light fixture to wall switch.

If the wall is heavily insulated push conduit through the insulation and then feed wires or cable through the conduit. Most light fixtures have two electrical wires with colored insulation and a copper ground wire. The source is at the switch and 2 wire cable runs from there to the light. Here a single pole switch controls the power to a light fixture.

The biggest challenge is planning the cable route and running it from the fixture to the new wall switch position. Just a ceiling electrical box with a circuit in it.
