This is from a 'dancing candle'. The LED illuminates a piece of plastic (wick) which has a small magnet on its base, that gets flicked by the electromagnet.
The component 'YB', seems to create a pulse, wondering what it is...
Also, when the battery starts going low, the magnet/pulse seems to pull current away from the LED causing it to flicker a little. I tried sticking various values of capacitors (electrolytic and ceramic) to decouple the LED, but does not seem to help. Tried this on the YB component too.
