You feed 230V through the bulb cold filament resistance - to an unknown tube or other component.
Accidental people can electrocute.
You are right, I did not take this possibility into account. The event is very unlikely, but still real.

Topic summary

The discussion revolves around safely identifying live phase wires without specialized equipment. Various methods are suggested, including using a voltage indicator, neon pointer, or light bulb. While some participants argue that a single bulb can indicate the presence of voltage, others emphasize the necessity of having a second wire or grounding reference to accurately determine the phase. Caution is advised against experimenting without proper knowledge, as improper handling can lead to dangerous situations. The consensus is that while inexpensive tools can be used, understanding electrical principles is crucial for safety.
