DIY Small Night Light: Easy Low-Power LED Project

If you are interested in DIY night lights, you might want to take a look at this article.
If you happen to have a balloon with LED beads, you can remove the LED strip and combine it with a charging adapter to make a small night light.
This night light has very low power consumption and a moderate level of brightness.
The building process is as follows:

Find a USB-to-COM cable adapter and take its USB male connector.

Connect the resistors in series and then solder them properly.

Plug it into a charger, and then use a cosmetic bottle cap as a diffusing lampshade:

This is what it looks like when it is lit up.

It can still stay lit for a while using capacitor power supply, and a power meter test shows that the power consumption is very low.
