Thank you for the inadvertent suggestion! I bought a microwave last year that has an LED panel that is ridiculously bright. I tried searching for something like this, but I didn't know what to call it, so I couldn't find anything. I ended up putting a piece of micropore medical tape over it, and it's STILL too bright.
I just ordered this from Amazon.
The 'Thanks' button seems to have a mind of its own. I see it on some posts, but not others. I'm not sure what's up with it.
