I too am a victim Miss D.... headsets and earphones.   Why do they need a light, you can hardly be aware of their communicative ability when they’re on your head.  🤔

The lights on bluetooth headsets/headphones are programmed to show their state which is useful when pairing them to a device for the first time.

Just checking Miss D but seeing as you don't like bright lights do you become destructive when fed after midnight perchance.... 

Wonder if anyone will get that film reference...

One of my all time favourite films    To boldy launch people off stair lifts where no people have been boldly launched before

And lights on headphones can be useful on planes when it's dark and you wake up and can't find them.

Oh yes ..that common problem 

Lights on headphones when in use  are simply there to indicate the human has switched off

I only ever use headphones on planes.  Perhaps you don't take enough fly away holidays
