Last night I was messing with the one that has 3 bulbs, one works, the other 2 will work if I move the white plastic part that makes up the base of the candle to around the bulb and hold it there or move it around. I even took one of the bulbs and tried it in a night light and it would not work. putting my hand around it had no effect. I also tried a ground wire to the base of the lamp. I am still puzzled.
