Materials:
dimmer switch, masking tape
Tools You'll Need:
6-in-1 interchangeable screwdriver
Before You Begin:
Turn off the power to the circuit and have your neon tester ready.
Barbara's Tips:
A dimmer may hum if it's controlling more bulbs than it was designed to handle. Make sure the dimmer is rated for at least the maximum rated wattage of all the light fixtures it will control.

Step 1: Getting to the Wiring
Unscrew the switch plate and the old switch and lift it out. If the box is metal, be careful not to let the screw terminals on the sides of the switch touch the box.
Step 2: Testing the Circuit
Touch your tester to each wire. If the test light stays off, it is safe to proceed.
Step 3: Refresh the Wiring
Before you replace any wires, especially on a three-way switch – note which wire attaches to each switch terminal. Use masking tape to mark each wire and write what it was attached to. Cut off the wires at the switch terminals and strip about 1/2" of insulation off the two cut switch wires.
Step 4: Match the Wires
You've got a lot of choices here, so pay attention: If your dimmer has two black wires it has no polarity, so twist each dimmer wire together with either one of the switch wires and screw on a wire connector. If the dimmer has a green wire, connect it to the grounding wire. If a dimmer has black and red wires, wire the black one to the incoming power line and the red one to the lights. Keep the wires well apart from each other during this process. Gently fold the wires back into the box and attach the dimmer to the outlet box with screws. Replace the cover plate and press the dimmer dial on to the shaft of the dimmer.
Step 5: Let there be Light
Restore the power and set the mood. You did it yourself!
