All you need is to install one of their modules that go across the load. The switch is drawing a little current through the LED bulb causing the highly efficient bulb to light up. The module is a capacitor and allows enough power to let the switch work and without lighting the bulb. I have found them at either Home Depot or Lowe's but a quick search at both web sites I could not find them. There are about 1/4x3/4x1 1/4 inches and were right with the switched in the store. The wall box was very full so I installed it at the light socket in the ceiling. The other option is to use approved bulbs, that I think have this type of device built in with the design of the bulb.
