FWIW- I use the 7-watt incandescent night lights in various colors to let me know when certain X10 controlled devices are on/off. (Water lines, pool pump, garage doors, space heaters in garage for my dogs) They are over the back door I exit to let me know what is on/off before I leave. (realizing this not a true tell-back circuit, it reminds us if something is in a safe state before leaving) I found mine bulbs at 1000bulbs.com.
Some I use to swamp out the leakage current of X10 modules when controlling high impedance devices such as LED lights.
I noticed that my Christmas lights being controlled by newer appliance modules were only dimming when the module went to the off state. The 7-watt bulb in parallel was not enough. I had to use 15-watt bulb.
I have a long vinyl fence on my property line. I ran wire inside the hollow fence and mounted miniature carriage lamps on the hollow posts. Because I used 60-watt LED bulbs, I had to go through an interposing relay controlled by an appliance module.
I just wanted to share this as ideas in dealing with leakage current and high impedance devices in the LED world we live in today and disappearance of incandescent lights.
