Hello,
I have a piece of audio gear which has an illuminated power switch. The
LED inside flickers. Should I replace the LED, or is something else at
play here? I was under the impression (for no good reason) that LEDs are
like light bulbs - either they work or they don't -- no flickering.
Thanks!!

Are you sure it isn't a neon tube? They do sometimes flicker when they
are
old.

LEDs can and do go intermittent. There is a particular model of Sony mini
HiFi, which uses a LED bar to illuminate the see-thru LCD panel on the front
of the tape deck door. It is very common for these to go intermittent and
flicker. However, in this case, I am inclined to agree with the rest that
it's more likely to be a neon lamp, that's just worn out. Usually easy to
tell. If the switch just has two or four spade connectors for switching the
line power, then the internal illumination will be by neon lamp.
