As someone pointed out, these kinds of bulbs don't blow. The reason is
that they are neon (hence the NE part number), not incandescent. No
filament = nothing to blow.

The usual failure mode is that the bulb fails to light up reliably, or
even at all, as it ages. The only cure is to replace them.

In the unlit state, a neon bulb appears as an open circuit.
