Got it working! To neatify things I used a small project box with a
connector to the PS and another
to the wire pair leading to the LED. The switch wire pair enters the
box w/o connector since it is
mounted close to the switch. I added a green LED on the box cover to
show when there is power to the circuit.
All I have to do now is to poke a hole through the wall to get the
red LED into the living room. This is a little
tricky since we have plaster walls, and drilling a neat 1/4" hole is
virtually impossible. I think I'll drill and then
insert a 1/4" steel dowell and fill around it with a hard plaster...
unsanded tile grout perhaps. Then pull out the dowell
and insert the LED. All that will be seen is the little red spot with
black ring. This will be near a desk with
other things around so attention will not be drawn to it, except when
it's flashing red.
Thanks for all your help.

Nice! Good idea making the red LED a flashing type.
The resistor you mention in your writeup is 1000 ohm
or 1K - not 1000K as the writeup says..
The appearance in the living room is great - barely
noticeable. Nice to see the photos of the completed
project.
