I will be mounting this externally in view of the neighbor's house on

like to have the neighbor (all year round resident) be easily able to

cottage.)
What should I use, neon, led,etc? It needs to be wall mountable,
and be easily seen, though it need not be very bright or large.
Suggestions appreciated. I just want to be sure it has a long
life so a burnt-out bulb won't be confused with no power.
Thanks in advance.

Over time, lights will be ignored.

Put in a relay that is held "off" by the electricity. After a
blackout, when the power comes back on, relay does not reset and that
allows the light circuit to come on. Then the neighbor will notice
that the light is on when it wasn't before. Then hook up your stereo,
too so they can hear the music you are blaring.

Excellent observation about 'always on' lights being ignored.

Perhaps a battery-operated light that's held OFF by mains power.
