Another point in the endless war against useless always-on LEDs. (My least favorite was a night light with a switch. It had an always-on LED when plugged in even if you switched the night light off. Instant e-waste.)



Working from home with my desk in my bedroom, I grew to hate the always-on, bright blue LED on my USB-C laptop dock. I get it, you're plugged in, go away and take your light pollution with you.


The case I bought from Frys for my last desktop build a few years ago has a power LED that lights up half the room. I taped a penny over it.


For desktops, a nice solution is to hook up the power led to the speaker connection. At some point, pc speakers stopped coming with cases as they did in the past. And power leds have been mostly useless for a long time.


Multiple electronics' LEDs in my room have insulating tape on them, mutes the light brightness a lot!


If you are looking to block these out, I can’t recommend these stickers enough - LED Light Blocking Stickers, Light Dimming LED Filters

They also have white versions


The cheap bunch of LED stickers that I bought 3 years ago has been so good with this. They were sold as "6mm Round 10 Colour Dot Sticker Circle Sticky Self Adhesive Label" on ebay.

LEDs on the electric toothbrush shining brigher than a thousand suns? Put stickers on them.

LEDs on the dog water fountain illuminating the whole living room at night? Put stickers on them.

The funny thing is that the LEDs are so bright that they still shine through the stickers. Except that now it's at the brightness level they should have had in the first place.


And it's a thousand times worse if those LEDs are blue.

I've taken to just cutting the leads or traces to those power LEDs. Problem solved.


I did that to LED fans that came with a case one time.

I like LightDims a lot. I realize I could just use tape, but I can always find the right size and shape that way on smaller devices, plus a little light comes through. It just doesn't shine.


Black electrical tape works too.


I use gaff tape, matte finish and it doesn't leave residue (usually).


The last time I cutout a blue power LED, it was so bright that it not only would light up the room the device (speakers) was in, but it would also light the hallway outside the room if the door was left open.

It was so bright that even two layers of gaff tape didn't resolve the situation.

It's crazy. I often wonder about the reasoning behind choosing to use these LEDs is. Does nobody actually use these device in the real world during development?


My guess is that the manufacturers have a ton of incentive to use the same leds on everything to cut down on component costs via scale.

So that basically leads to them purchasing leds that are powerful enough for all uses and using them for everything, ie, they're way too bright.

Usage is entirely secondary

the point is so that you can find the light in the dark. it may be poorly made or unecessary but I can at least in theory understand the logic.
