That’s the question. When cooking and then pouring the water into the sink, for 10 seconds the lights on the counter turn on. These lights are usually broken and refuse to turn on manually. The lights are a strip of little LED bulbs glued on the cupboard .
i have a theory but i am not an electrician
EDIT : case solved by GIGACHAD (that’s his nickname)
I suspect the vibrations of the pouring water are making something make contact with something else and that is turning on the LEDs.
Test this hypothesis with the same pot full of cold water.
When thee red bulbs in My under cabinet lighting are staring to die I have found the need to be tapped to turn on. I replace them and the new ones work fine.
