I moved in to a home, last person took their light fixtures with them. One pair of light fixtures are attached to a switch.
The fixture box closer to the switch has ground/copper, two white wires nutted, two black wire nutted, two red wires nutted.
The fixture box farther from the switch has ground/copper, two white wires nutted, two black wire nutted, one red wire nutted.
Which wires should I be connecting to my light fixtures in each box?
You want to hook your fixtures to the red wires, the white wires and the bare copper wire in each box. The red will be your switched hot, the white will be your neutral and the bare copper will be your ground. Remove the wire nuts from the red group and single red and attach your fixture wires, probably black. Remove the wire nut from the white groups and attach your fixtures white wire. If your fixtures have a ground wire or screw, attach them to the bare copper wire.
