2pcs Light Blocking Stickers, Light Dimming LED Filters for Routers,Clocks and Electrical Appliances, LED Covers Blackout (White) (D21111)

I have used black light blocking stickers to cover up annoying flashing LEDs on modems and other equipment. I found them totally effective in blocking light ..….but a little unsightly on white equipment. I have been meaning to buy these for some time and read reviews which suggested that they were less than effective at total light blocking. Nonetheless, went ahead with the purchase ………and discovered that those reviews were accurate. I have doubled up on the stickers but light still passes through. Still, on the positive side, the white equipment looks smarter with the replaced black stickers being overlaid with these white stickers!

I bought these along with some black ones because I was sick of the led lights on all my devices. The theory was that the white ones wouldn't be so obvious on the white devices. The black ones worked perfectly but the white ones just reduced the light instead of blocking it. The hole purpose of buying these was to block light not reduce light so I don't think they're fit for purpose.

I bought these for my electronic temperature thermostat. Sadly light still shines through

Awful, ive had the black ones which block the lights. These do absolutely nothing.
