Wireless adapters, USB drives and external hard drives often blink when they are doing something. So it's after hours, you turned off the lights, ready to immerse yourself in some kind of more or less interactive experience, and now the entire room lights up blinking.
I don't need the blinking. Why do I have to use duct tape to get peace? I will probably notice if the device stops working without the blinking. Besides, if it stops blinking it could just as well be that the blinking function isn't working (what a shame that would be). I can't tell without trying the device anyway. So, for the love of the internet, stop blinking.
Does it need to blink? Probably it doesn't. For things that are charging and doesn't have a display, some sort of indication is good - I don't typically stare at my electric tootbrush when it is charging (I don't usually have it on my desk).
I really don't need blinking. Remove it.
