Hi, my name's Andrew Dryden, and I'm going to show you how to change a bathroom light fixture. Things you'll need: screwdriver, ladder or step ladder, which is optional, mounting screws and insulated pliers. First, turn off power to the electrical box. Remove the old fixture. Begin by removing the bulbs and shades. Disconnect the wires from the old fixture. Make sure three-quarters of an inch of copper conductor wire is available. Twist the line wire end with the fixture wire. Screw a wire nut over the twisted ends to secure the connection. Insert the mounting screws into the attachment holes and turn a few times to secure. Tighten the screws of the fixture. Finish the installation with the bulbs and shades, and finally, turn the power back on to the electrical box. And that is how to change a bathroom light fixture.
