Look very carefully at the bulb.  Below the filament, just above the glass
bead, there should some fine wire wrapped around the wires which hold the
filament.  That's where the electricity is conducted.

Considering how the entire chain of lights should be considered hot, I'm
surprised I've never heard of anyone getting electrocuted from these things.
It seems like a setup for disaster:  cheaply-made hot lights and aluminized
tinsel.  If one finger of the tinsel reaches inside a bulb holder, the
whole tree becomes hot.
