How can you tell if it can be subverted? Here's a paper about subverting the Apple Mac camera led indicator from userland:

If the LED were simply wired in series somehow with the mic power supply I imagine it would be easier to tell. The problem with the Mac LED indicator was that it was controlled by a microcontroller that was ultimately accessible via user land. It's harder to surreptitiously bypass a simple electrical circuit.

As a user, you can't. The hardware manufacturer has to tell you.
