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.
