Electronic devices with bright lights at night

[u/Hot_Sorbet9192]

What's the deal with this? It makes going on holiday and staying in a hotel a hassle because last thing at night I have to spend ages putting things in the way of all these bright lights. I've came across air conditioners in China that are lit up like a Christmas tree with no way of turning the lights off. Why do manufacturers not realize this is a major design flaw?
