In the basement staircase of my older home (inside my attached garage) I want to eliminate a 3 way switch at the end of a circuit, and install a light fixture near the switch I want to remove - at the bottom of this staircase.

When I removed the cover from this switch I found 4 blue wires, one of them marked with black tape. The 3 way switch itself is very old (circa 1959) with four brass screws, two at the top and two at the bottom.

Can I eliminate this switch, and install a needed light fixture, using these 4 blue wires from this switch?

The switch at the top of the steps is the switch which has power coming into it.

electric codes often require a switch at both top of steps and bottom for safety.

your project may cause home inspection issues at home sale time in the future. then if your selling you will be REQUIRED to have a registered electrician change it back..... costly

just run a new line and save yourselves tons of problems
