Light Blocking Stickers - 144PCS Light Blackout Covers with Tweezers for Electronics Light Dimming for Routers, Monitors and Electrical Appliances, Block 95%-100% of LED Lights (Blackout)

I bought these because I am a person that cannot sleep with any kind of light in the room. Even a small light on the tv. I got a mirror with a LED touch button that shines a very bright blue light and it makes it impossible for me to fall asleep. Put one of these babies over it and no issues since. No light escapes from behind these stickers.

These block the light in my air purifiers and TV’s around my home and I love them. Totally blacks them out and will def order again.I’d rather have more standard shapes than some of the oddly shaped ones but these still do the trick very well.

This worked so great in our small RV. I put it on the bright lights that didn’t need to be used daily like the microwave.

Desperate to cover up the lighting and since I really don't need too many of these (bought tons for a previous apt but then could not find the old saved stickers in storage boxes), I hadn't thought about how bad the black stickers would look on a white alarm!

LOVE THESE. I can sleep through almost anything, but my wife is a light sleeper. So many of the electronics in our rooms have lights that are so bright when you are trying to sleep. These work great to block out those annoying lights and keep your room nice and dark when trying to sleep. The variety of sizes is perfect and even includes some extra large ones for larger lights or to cut the perfect custom piece. Comes with a cheap pair of tweezers to help with application, but the quality of the light stickers make this product well worth the purchase.

I am sensitive and have a hard time falling asleep when there is light. However, there are a lot of home appliances that emit light. I used this to cover everything up. It's really the best! Everything is covered! The variety of sizes was very helpful.

I bought these to cover the lights on my computer monitors on my gaming rig. They’re right next to my bed and the flashing blue light makes it incredibly difficult to sleep at night. Now that’s no longer a problem! There completely block the light and I’m back to the bliss that is total darkness

I’m not sure why these stickers have gotten such bad reviews, so glad I didn’t read them first. They worked just as advertised for me, I did have to use more than I thought I would need but that’s not the fault of the stickers. My suggestion is to place the stickers wherever needed during dawn or dusk hours so you can actually see the light you want to conceal. You’ll need a big enough sticker to not only cover the button but also the glow it emits around the sensor button. I had to cover half of a smart plug because the blue light was bright and the plug has a weird grill look to it. With these stickers I no longer have the need to place blankets, pillows or clothing over various obnoxious glowing lights in my bedroom. I like it so dark I can’t see my hand in front of my face when I sleep, thanks to these stickers and blackout curtains, that is now accomplished!
