DIY Rechargeable Sensor Night Light Upgrade

If you have a rechargeable sensor night light and are interested in modifying it, this article is worth checking out.

As shown in the picture below, this rechargeable sensor night light comes with features like always-on mode, motion sensing, and brightness adjustment. The main advantage of a night light is that you don't have to fumble around for switches in the dark.

If you don't have a spot welder, you can simply use solder paste and an electric soldering iron. After assembly, the result looks like this:

After soldering, here's a comparison with the original factory version:
