Voltage drop on a shower causing a light to come on

Sam Ayre

Hi everyone I was hoping someone might be able to help I came across a video on YouTube where when the shower was turned on it caused the bathroom light to glow while the switch was turned off. The person later explained it to be a voltage drop on the shower but to my understanding something like that wouldn't have that kind of effect ant guidance would be great thank you.

    What do you mean by, "glow" please? Is that the same as, "shine" (brightly)?

    I have measured 50 v from L-N in a lighting circuit which was turned off, but only 1 mA was flowing. That may be enough to cause a CFL to flash. The one above my bed used to flash at about 1 Hz, but it was visible only once my eyes were properly dark-adapted. (There is now an LED lamp there and it does not flash.)

    Petty much it has a constant dimmed light to it almost as if it's just been turned on and is beginning to warm up
