Note to others: Don’t do this unless you’ve verified that your particular LED already has the resistor built into it, which is how those work.
Otherwise, hooking a bare LED up to DC voltage tends to eventually convert it to a smoke emitting diode, especially since LEDs have an inverse temperature/resistance relationship. The hotter it gets the lower its resistance becomes so the more current it draws so the hotter it gets so the lower its resistance becomes so the more current it… pop.
Heck, technically the resistor isn’t even needed with an led that can handle the power from a USB brick

At least for a little while!
