LightDims LED covers are on sale at Amazon

You're in bed, feeling nice and cozy under the covers, about to drift off ... when you notice the blinking light on your router taunting you from across the room. "Welp, there goes any hope of getting a good night's sleep!" you think to yourself. If you're someone who has trouble catching zzzs unless the room is pitch-black, you're not alone. But there's a super simple (and affordable) solution: LightDims LED Covers. These stickers can be placed over pretty much any light emanating from your electronics to reduce/eliminate the glow, and — get this — they're down to about $1 for a sheet of over 100 at Amazon!

With just one sheet, you'll be able to block out the light from every electronic and appliance in your house!

We know, we're wishing we'd thought of these, too. But hey, good to know a simple solve exists for this pesky problem! (And doesn't involve eye masks that never stay put.) Each pack of LightDims LED Covers includes over 100 stickers in a variety of shapes and sizes to fit over different lights, whether you want to reduce the glare from your alarm clock, microwave, power strips or tech gadgets. Some people even use them to cover the cameras on their laptops as a safety precaution.

What makes these stickers so genius is that they're designed to block out 50–80% of the light they're shielding, making the brightness less intense for sensitive eyes, but still visible to ensure your electronics are on and functioning. That said, if you'd like to obstruct the light entirely, you can layer the stickers for a complete blackout effect.

To use, just peel and stick — and if you have to remove them, they won't leave any residue behind, unlike tape (and they look so much better, too!).

With 8,600 (and counting!) perfect ratings, LightDims LED Covers are a fave among Amazon customers:

"They work!" summed up this relieved reviewer. "I have several devices in my home that have eye-piercing operating lights on them, including some in my bedroom. If I get up at night, they wake up my brain too much, but I did not want to cover them with something opaque, as the lights are the only way to know if something is on or not ... love this easy and inexpensive solution to an annoying problem."

"These are a great investment!" gushed another satisfied shopper. "They layer so you can decide how much of the light you want to block. This is useful for indicator lights you still need to see, but can create enough filtering to keep it from being annoying. I suffer from migraines, and little lights on phone chargers and power cords would drive me crazy when I needed to rest in a dark room. Problem solved!"

"Hello darkness, my old friend," wrote a final fan. "I LOVE these. I cannot sleep with any light. It absolutely drives me nuts. I need blackout curtains and can’t even deal with the littlest of light from electronics. So far I’ve used these on surge protectors, my printer and my modem. They work great and it looks so much better than a piece of electrical tape ... I truly had no idea how much joy these little blackout stickers would bring me."
