I've always struggled to fall asleep with even a moderate amount of light in the room, and I used to go crazy trying to cover every small led to make things easier for me. It took me far longer than it should have for me to realize that it would be easier to cover my eyes instead, and I bought a nylon sleep mask on Amazon for a few dollars. It's literally been life changing how much my sleep improved after that. If anyone is bothered by this specifically when trying to sleep, I'd highly recommend trying out using a mask to block light when sleeping; it's really cheap to give it to a shot, so you don't lose much by trying, and you might end up winning the lottery like me.
