What if there was a real Edison bulb having a night mode?

I imagined it having a circuit to dim it during the night, like a night light. For example having a few filaments inside a bulb and switching between parallel for more light and serial for less light.

Our home was not well insulated and in a corner of our sleeping room we had condensing moisture (it was unavoidable because in the corner the temperature was way too low,the lowest I had was 9°C or 48°F). I thought about putting some nichrome wire (for example terrarium heating wires) in the corners and having a switch between parallel and serial as a means for two different power levels. The idea is a parallel switch. If you turn the switch, multiple contacts are connected and disconnected. If you connect the wires cleverly, you can switch between parallel and serial. Luckily our landlord found a permanent solution for this problem after I showed him the measurement I made, so I didn't need to build this.

So that's why I started to get a picture of an Edison bulb that has such a switch inside its base.

It sounds like you're trying to backport the LED smart bulb to a 19th century platform.

Maybe that's not needed. Do 19th century light bulbs support docker?

Yes, if you can get the sockets and 2° bulbs small enough to fit within the glass envelope of the 1° bulb.

Capable bulbs have VT-x (vitrification technology).

Look up the so called three way bulb. It had two filaments and could have one, the other, or both on.
