LED light Candle Set
LED candles that use mini LED lights from Amazon (link below) and are designed to press fit into the flame and the bottom part of the candle. You should be able to just turn the flame to turn off and on the candle.
2.5 inch round : 3,5,7,9 inch heights
Two suggestions:
1) use the tree supports for the flame part. It's easier to get out than the normal
2) for variety, mirror the candle in your slicer. The originals have a left and right version, but this is just based off of the left version.
