Default LED spec for phone line?

wrote:
I want to put an LED to test my phone line, which I found to be ca 50v.

Where/how do I find the right LED?

THe LEDs at Radio Shack are all like 2v (yea I remember VCC of 2.3 on diodes
in my EE2 for non EEs course).

Should I just use a regular bulb, like the kind used for Christmas lights,
instead? (what about the LEDs used for CHristmas lights? Shouldn't they
work?)

Besides, I really only want ONE LED.

They are all pretty much the same except for current requirement. Most will
light with less than 5 ma. Know ohms law ?
