One of the comments linked to an article about keyboard problems caused by a LED, which was previously discussed here: https://news.ycombinator.com/item?id=36581204 https://news.ycombinator.com/item?id=36581204 - Repair adventure: A single white LED causing stuck keys on a RN988 keyboard (2023-07-05) I wasn't thinking about the color of the LED at the time, but after reading this article, I wonder if we should prefer products with green LEDs in general, like green LEDs are just more reliable than blue/white LEDs for some reason? Also, I can't seem to find microwave ovens with red LEDs.
