I looked at the paper, but I think these lamps light up because these long wires carry AC. The changing current creates changing B field and this produces EMF on these lamps. However, in my case, there is no varying B field, what I mean is there is no inductive EMF. This example looks irrelevant in this context.

@Farcher I am sorry not to mension that. It is just put between the plates of the capacitor, there is no electrical conducting path between the lamp and the plates.
