HI. I am trying to find an LED that can be powered by just the audio power of a typical stereo amp's single-channel output. NO battery or other voltage input, just the audio signal from the amp to the speaker. Does not need to be particularly bright, blink, or do anything but light up with the audio power. I am assuming i need something that will run on 10mV or less? I cannot seem to find anything like this searching online. I am sure such an LED exists, as i have bought VU meters that run on just the audio signal with no power. But i am only needing a single LED to light up with audio power. ANY IDEAS or know where i can find such a product??
In case you are wondering the purpose, i am trying to back-light an epoxy mold for a logo that will light up when in use on a custom speaker system...
THANKS FOR ANY HELP YOU CAN PROVIDE!!!!
