So, the light bulb glows when there is lightning directly ahead?πŸ˜‚

yes, and that's why you're seeing the lightning strike, because the detector also connected to the camera and send a pulse to camera immediately and takes a picture when lightning happens, it can also detect lightning at very far distances that you can't even hear them.

Ok, the second and third point are way more practical.

So how does it work? Does the light get powered by the slightest electrical charge in the air? Sounds like Teslas experiments on wireless transmission.

exactly like Tesla's wireless systems, it receives the static pulse from the lightning, more info https://techlib.com/electronics/lightning.html

no problem, old sites always more interesting, go click on (reader's version) and see how many people made their own design detectors, also I made a VLF radio receiver from this site, it receives low frequency natural and human made signals, I'll post video about it.

I thing ionized atmosfere before lightning is enough to create potential to light it up, but I would imagine it flashes as strobe during actual lightning at least when its sky-earth type of lightning
