Keith,

I have a commercial (AT&T?) device in a sealed package that turns an
outlet/lamp on when the phone rings. Don't believe it has a schematic though.

Buy one at Radio Shack for about $10. I got one for my very hard of
hearing M-I-L who really loved it. I rigged a light next to her TV. When
it flashed, she answered the phone. Her hearing aid was designed to
receive signals from an inductive ear piece in the phone.

If you really want to build something (why not? this is a HomeBrew newsgroup!) there are several choices he

RS used to sell such an item...plugs in and strobes when the line rings...
use them a lot in broadcast use.....

All Electronics has boards that will do this, 5 for $1.00.

The easiest is a neon bulb NE-2 [don't use an NE-2H] and the largest
resistor to get it to light. Probably in the 10's to 100k. This isn't
bright, but needs no power. This was used for many years in many circuits.

If it is not bright enough, then one of the other circuits with a high
resistance sense and external power to light a bright light is needed. That
