How would you make one on/off control for dozen(s) of battery operated tea lights?
My first choice would be some sort of wireless remote control. I have found some remote controlled tealights I could buy - but they are way too expensive ($10/ea). I thought about replacing the tea lights altogether with a light string. An extra advantage to this might be to connect to wall power or one longer lasting battery which would save having to replace many little tealight batteries over time. However this would be OK only if I could hide the wires out-of sight. All the light strings I've found so far have wires too thick to hide, They come in sets of ten lights or more - and I don't know what would I do with the extra lights on the string.
