One of the oldest questions mankind has ever dared to ask. 
Sure it does go off. At least that’s what I thought until today. But then I took a picture of the fridge light when the door is closed (self-timer) to prove my presumption and it turned out that the light DOES NOT go off in my fridge. It’s just dimmed. WTF?!
Compare the pictures below. Both were taken with the same shutter speed (1/350s) and aperture (2.8) so you’ll notice the difference.

What about your fridge? Does the light go off or is it just dimmed too?
