- Greetings. I have a couple of applications for a device that flashes
- a light (maybe even a strobe) when a plain phone line rings. Such a
- thing must exist, but I can't find sources. Please email to me and
- I'll summarize. Thanks!

- [Moderator's Note: The easiest way to do this is get a neon test thing
- from Radio Shack (or anywhere else ...). Just wire it parallel to the
- phone line. It does not draw enough current to take the phone off hook
- but will flash in sync with the ringing of the phone. I have an
- appliation here where there are several lines going into a computer
- which is used for voicemail. No one wants to sit and listen to those
- bells on the incoming phone lines ring all the time, yet it is very
- important to know if for some reason the computer is not answering the
- line ... with no bell it would never be noticed if something had gone
- wrong. So, I have several 'beehive lamps' (the little plastic things
- with a dome on top and a neon bulb mounted within) mounted on the wall
- with double-sided tape. Wires run to each from the associated phone
- line. They flash on for a couple seconds each time a call comes in on
- that line. The only line with an actual bell on it is the final line
- in the hunt group -- when it rings, it serves notice that the computer
- has a full house, at least for the time being. I also have a little
- counter installed on that line which increments by one each time that
- line rings ... by viewing the register, one can see how often a full
- house occurred since the last time the register was reset. PAT]
