Light Blocking Stickers,Blackout Sticker for Electronic,2 Sheets Cover White and Black, LED Covers,100% Blocking(Cut-100% Blocking White and Black)

I bought these to cover some LEDs on my keyboard that were annoying and couldn't be turned off. These are super easy to use and come cut in all sorts of shapes and sizes and then can also be cut to suit your needs. The white and the black perform the same, but do note that the opposite side of the white sticker is completely black. They completely block light (no bleed at all!) without leaving sticky residue when removed. I think for the price they are of great quality and value.

Very pleased that the shapes and density of the material block out the annoying light and can be pulled off and placed elsewhere to black out the light. I have used both the black for dark surfaces (video players in my headrests) and the white for lighter surfaces, such as my dehumidifiers, and have been pleased with both. The stickiness is maintained and is easy to apply. Great value for the money. I recommend this product.

Bought these because I am sensitive to light when I’m trying to sleep. I have a mini split AC unit in my bedroom with two glaringly bright green lights which pierce my eyes and prevent me from fully resting. These stickers did the trick. There are plenty of sizes to choose from and I appreciate that there are white and black stickers. I had to use more than one to get the effect I wanted, but that wasn’t a problem.My only criticism is that they are extremely hard to peel off the backing.I would definitely buy these again if I run out thought.

By necessity, my computer workspace is in my bedroom. That means that at night, I have all those annoying indicator lights on the computer and the router blinking to show they are doing whatever it is they do, even when the computer is off, as well as the lights on the LED desk lamp buttons, the KB switch, and even the damn power strips.My solution up to now has been little pieces of duct tape placed on top of blue painter's tape (because the painter's tape won't leave a residue on the device) and color over the duct tape with a permanent marker. Not only is it tedious to make such light blockers, I could never cut them as small as they really needed to be. Also, after a month or two of dusting, the edges of the painter's tape started to peel up, making it necessary to I do it all again.THESE are perfect, though. In most cases, they block almost all of the light; stronger lights might be seen VERY DIMLY in a completely dark room. I didn't have hope that the white ones would work as well, put just like my tape trick, they are one color on top and a different color (black) underneath. I have actually used these on my LED desk lamps on the black power switches because that way I can see where the power button is located.They are still in place and don't peel off over time. I also appreciate that they come on a clear backing so you lay the sheet down over the item you intend to use them on to make sure you have the right size before peeling them up to place them.The ONLY thing they haven't been able to help with is an annoying power strip I have that has blue lights in the USB ports, a "power on" indicator, AND blue light framing the power switch. While I was able to cover up the ports and the indicator light, the switch is just not possible to really cover in an effective way. That isn't the fault of the light blockers, it's just the design of the power strip.

Works but brighter lights require two or three layers.

I have the mixed black/white package. Finally, a total blackout of unnecessary lights on all the electronics. I am taking a few on my travels for relief from the bright LEDs that interrupt my sleep in hotels. I'll remove them on checkout, of course. These stick on well, remove easily, no bleed-through. Price is right.

These little stickers have really helped me sleep better. They cut the light emitted from my electronics just the right amount. I like the variety of sizes but wish there was one extra uncut sheet. They stick well while still being removable. This product has been a game changer.

The IEHENG LED Light Blocking Stickers are durable and have stayed firmly in place without peeling, which is a big plus. They do a good job of blocking light and have made a noticeable difference, though there’s still some light bleed—mainly because the stickers are so small. I had to use 6–7 just to cover one device since the sheet is barely larger than my iPhone 12 Max. The black stickers are more effective than the white ones, but both work well overall. I think if the stickers were larger, the light bleed wouldn’t be an issue. The only downside of them working so well is that now it’s hard to tell if a device is on, which I get around by only covering most of the light and leaving some off, but on larger devices it's not an issue because the stickers are smaller than the light source! While I kept them because it wasn’t worth the hassle to return, they do feel overpriced, and I’d probably go for a cheaper option next time. They’d be perfect if priced around $4.99 or just add like 3 more sticker sheets to the pack instead of only 2. Also make larger stickers!
