I found this thing in a bag of internal computer cables. It looks like it might be a USB device? I don’t dare to insert it into anything, though. Especially with that scary symbol: A black bulb!?

It’s USB powered LED lamp. Random seller: https://www.electronicscomp.com/mini-led-light-ultra-thin-ultra-light-portable-usb-small-led-lamp-camping-night-light (not an endorsement). You can take the product images and do a reverse image search to find more.
Aaah. That makes sense. Thanks. 😀
Here’s the device in action. Neat!
