holabr,
I have this same problem at Halloween with those flame flicker lights. The appliance module will not help because it contains the same 'local on' feature circuity as the light module, which is what is causing the glow when off.
You need an additional 'bleeder' load. Plug in one of those 3-way cube taps into your module, plug in your flicker light AND another load such as a small night light, a small mini light string or a plug-in air freshener. I use the latter because I don't want any additional brightness near my flicker bulbs.
