Realistic Battery Operated Candles
I think wax candles look more realistic but whatever.
The Battery-Operated Flicker Candle contains three LEDs that produce multiple points of randomly shifting light, creating a glow that flickers, rolls, and casts dancing shadows, just like a real candle flame. A microchip inside the candle creates random, non-repeating light patterns.
