I remember of a security flaw on Apple laptops, where there was a exploit on a light indicating camera activity. It could be turned off but the camera was still recording. So yeah, software based kill switches looks like a security flaw waiting to happen.
The ubiquitous webcam indicator LED is an important privacy feature which provides a visual cue that the camera is turned on. We describe how to disable the LED on a class of Apple internal iSight webcams used in some versions of MacBook laptops and iMac desktops. This enables video to be captured without any visual indication to the user and can be accomplished entirely in user space by an unprivileged (non- root) application. The same technique that allows us to disable the LED, namely reprogramming the firmware that runs on the iSight, enables a virtual machine escape whereby malware running inside a virtual machine reprograms the camera to act as a USB Human Interface Device (HID) keyboard which executes code in the host operating system. We build two proofs-of-concept: (1) an OS X application, iSeeYou, which demonstrates capturing video with the LED disabled; and (2) a virtual machine escape that launches Terminal.app and runs shell commands. To defend against these and related threats, we build an OS X kernel extension, iSightDefender, which prohibits the modification of the iSight’s firmware from user space.

DiskFiltration: Data Exfiltration from Speakerless Air-Gapped Computers via Covert Hard Drive Noise
Edited to correct.
The above is wrong: it refers to the use of the Hard Disk to exfiltrate information as a kind of audio transmitter, not receiver.
The previous writer (kpedersen) was correct in referring to an IEEE paper
IEEE: Hard Drive of Hearing: Disks that Eavesdrop with a Synthesized Microphone ( DOI: 10.1109/SP.2019.00008 )
Nonetheless, the Ben Gurion Cyber Security Research group do some interesting stuff.

For old people? Took awhile for me to explain the red light on the PS4 means off to my dad and he still doesn't like it. "Well if it's off it should be off. I don't want another f'n light in my room at night. And who TF wants that hibernate crap with the extra bright light?"

I hated my Roku TV in my bedroom when I first bought it a couple years ago. I didn't realize that it had this bright, bright white status light dead center on the bottom about 3 inches long with no options to turn it off so my bedtime routine ended up being stacking the first two books from the Vampire Chronicles up front of that light...couldn't tape it up because they placed the IR sensor in there...the bastards. About six months or a year later a firmware update added the ability to turn off the light bar. I was so happy.
The PS4 is like using plugin-free GNOME or my Roku TV-- you have one way of doing it and if you don't like it you might as well consider yourself up the creek w/o a paddle because you may or may not get that feature.
