This new model also shows the relation between mechanics and electronics. With this realistic model, a pulse is relayed through  percussion to the coloured light-emitting diodes. 
The colour bar begins again to lift with each percussion. Two batteries provide the electronics with power. 
With this model, the Wilesco funfair series is enlarged with this eye-catching model.

The batteries needed are not included.
