Red Light Film
A roll of red film with a sticky back that lets you block or dim glowing lights in your home that can disrupt sleep. Easily removable.
Also great because you can cut it to whatever smaller size you might need. I personally use it to cover larger light panels, like the power panel on my sauna. For smaller applications, I use these to cover things like my smoke alarm light, air filter lights, radio lights, etc.
Note: I try to avoid linking anyone to Amazon, but unfortunately this is one of those things that’s only widely available on Amazon or Walmart, neither of which I like to promote. That said, I encourage you to find an alternative source if you can. (Let me know if you do!)
Otherwise, below is a link to purchase on Amazon.
