Whiskey Barrel Fountains

Can submersable fountain lights be used in whisky barrels?
I have a whisky barrel fountain with a pump in it.Can I use the submersible mulricolored lights for ponds?Has anybody ever tried this in a whisky barrel and if so how does it look?
You bet you can! We have some on display (I work in a Garden Retail Center) and they look really cool when we’re closing the store at night and most lights are out.
