12V Lamp Flasher Circuit Analysis With LTspice

The circuit we study in this video is of the kind that you find on many websites when you search the internet for something like a car bulb or 12 V lamp flasher circuit. I discovered it when a version of it was posted at the Elektor Labs project website (see https://www.elektormagazine.com/labs/how-to-build-12v-lamp-flashing-circuit).

This is one of those circuits that get copied over and over again without any explanations or technical details because either nobody knows how it works or nobody cares about how it works. Therefore, I decided to analyze the circuit with the help of #LTspice.
