At 3:19 there a demonstration of the LED effects in darker lighting:)
This was the demo video for a brand new Harley Benton that has been professionally modified to include an LED infinity mirror with sound to light. It has a Hot Rail humbucker pickup fitted for minimal noise. As before, it runs off four 1.2V rechargeable AA NiMH batteries that power an ATmega chip along with the LEDs.
This guitar has been sold but more will be built soon....
