Mildly Infuriating

I hate this trend.

I'm quite sensitive to light, and some of these LED's are stupid.

Thought I read somewhere it’s cheaper to get these super bright LEDs, so they use those rather than something easier on the eye.

I think we should also have a review on non-functional (decorative) LEDs on the gadgets we buy, especially those cheap chargers that decide to light up the whole room with blue.

I used to work in electronics manufacturing. I won't give my title because it was a shit title and didn't describe what I did well at all. I think that was on purpose to keep our salaries low.

I engineered final assembly test systems. Like the product fully completed. Most of these devices were commercial in nature.

My man, the testers fucking LOVED LEDs. Because LEDs not turning on correctly always means the device fails.

I hated them, because was really fucking hard to automate testing of LEDs. LEDs emit a wavelength, or combination of RGB. Because of the brilliance of my sales engineers, we used computer vision to automate this testing, NOT sensors. The reasoning? Much denser LED placements.

But guess what happens when your supply chain and manufacutirng is entirely Chinese and your product is designed and prototyped and originally manufactured here? YOU GET THE WRONG FUCKING COLOR CALIBRATED. I'm not shitting you, it was a tiny difference in Red wavelength. Tiny. but computer vision doesn't read wave length, it reads color.

LEDs make testing easy for humans. If you just need to see them light up? Everything is great. Bonus points for brighter LEDs for faster moving tests. Faster moving tests = more profit. Human testers means you don't spend money on automated testing and and can quickly repurpose humans to see if an LED is on.

My in-laws power outlets throughout the whole house have always on LEDs on them. It drives me crazy. My mother in law likes it and says they are like night lights, but the whole house is so bright at night.

I regularly take nail polish and paint over these infernal LEDs in layers until they are at a brightness that I find acceptable. Red are not so bad, but blue LEDs area nightmare. I have a cheap Chinese headlamp were the blue battery indicator is brighter than the red led for illumination, and the blue reflects off my glasses into my eyes.

Fully agree. One of the worst offenders is the PS5 whose standby lights can’t even be covered with tape properly because they’re complex curves. Even the clocks on my stove and microwave are too bright. I happened to have some black “washi” tape (basically masking tape) and it did a nice job of dimming them without looking out of place.

Sadly appliances with useful dimming options are getting very rare.

In the same boat as OP and other commenters: electrical tape and sharpies FTW

I have an old Samsung screen, which has a bright blue LED when it's working. So far, so good. If you turn off your PC, the same blue LED starts to blink. Looks like you get raided by the police. How can anybody think it is a good idea to have a blinking LED for a device that isn't used?

Even the small white leds on my pc are annoying, I've recently used a black sharpie to dim them, it did wonders.

Those bright LED interfaces are called "Abusive Appliance Interfaces" by Nathan over on the Toasty Tech website. It seems like there's more people that are being annoyed by the bright lights than I thought.

why are they blue!!!

Literally chose not to buy a powerbank because the power button flashed blue as bright as possible. my PC has blue LED's on the front for status indicators, and i put some black nail polish over them to block out about 80% of the light.

it gives you a bit more appreciation devs who add in functionality to turn the LED off. My fan has that which is really nice, and my portable AC. Even my access points you can change them.

But still so many products with LED that cannot be changed or disabled so I have to use a piece of electrical tape.

You can't tell anyone this, but I have a friend who is deep inside the insurance industry. Some of the big guys have invested heavy into LEDs. So to maximize the LED investments, they give manufacturers safety discounts for every LED they can attach to their shit. Big guys make some extra zeros for their accounts, and sharpie and 3M get some splash, too.

hashtag-not-an-engineer-but The vast majority of products you can just pull the LED. Don't resolder, just pull it out. If it goes badly, you can either just put it back, or replace with a "non-LE-"diode of the same spec.

Don't even get me started on VEHICLE HEADLIGHTS ! >:(

At least you don't live in Japan where everything sings to you

I have a pair of underpants draped over my internet router.😂😂😂 Really defuses the 🔆 🔆 brightness

I'm exactly the same as you. One tip I have is if you can open the device use masking tape on the inside of the shell where the lights shine through so it's dimmed but you can still see the lights if you need to/it's helpful to. I do this on some of my handheld gaming consoles so I can play them in bed and not be blinded by the LEDs

The worst is when you find bright LEDs all over a hotel room. Becomes like a buckaroo style puzzle game trying to cover things up with whatever you've brought along with you.

I seem to be fortunate that both my last cable modem and my router have built-in options to turn off all LEDs, even the power LED, for aesthetics.

Search for “blackout tape” or “dimming tape” and you’ll find dark sticky tape in different degrees of transparency that you can use to dull or block these annoying kinds of lights. I learned about it through my wife, whose sleep is easily disturbed.

You shouldn’t have to buy this and make the effort, but I’m trying to make a practical suggestion.

I have a bottle of black nail polish. Every LED in my bedroom (except the smoke detector) is blacked out.

100% agree. I have tape over the lights on my PS5 to keep my room dark at night. Plus I turn all my monitors off...and sometimes put something over my router to cover up all those blinking lights...and the Oculus Quest charging light....

I purchased a black paint marker. When I get new electronics, I turn off the lights at night and all eye-offenders get the hose.

I keep the modem from my ISP in its box with holes cut out for the cables. Even with LEDs covered with an electrical tape, it would just shine its blue blinking lights through all the cooling grilles and light up the whole bedroom in the night.

Man, that reminds me of an art installation that I saw many years ago, where an artist set up a bunch of home electronics in a completely dark room so that their LED lights looked like star constellations.

It was kinda beautiful and yet a reminder about all the "light pollution" we get from these devices, basically what you are talking about.

I tried to look up the name of the artist and that art installation, but couldn't find it.

Depending on the device I use electrical tape or the liquid electrical tape. It works quite well at blocking the light.
