Or simply, it could be that the carefully designed device that turns the lamp off does not work. Isn't that what we are trying to test?

Well I feel that first we need to prove that the light goes off when we press the button besides the door that gets pressed every time we close the door.
Then we can add some padding behing the door so that it presses the button before the door is fully closed. If the bulb goes off then we can prove that, when the door is fully closed it would press this button and switch off the light.
But this solution works only when the lightning system is based on this switch getting pressed .. there might be newer models in the market.... which dont follow this technique.

Hi ppl,
got anothr idea ... eureka.
Well what we need to do is attach a very sensitive voltmeter/Ampmeter to the line supplying power to the refrigrator, now open the door and see the reading .. and then close the door and see the reading .. if the bulb is switched off then it would consume less power.

Put your wife's favorite plant in the fridge. A plant needs light. If after a week or so the plant dies, it proves there was no light when the fridge was closed.

Or alternatively, it proves that the fridge is cold.

Set the fridge to the highest temperature setting. This will cause the ice cubes to melt and will solve the problem of watering the plant too

Or turn the fridge inside-out.

I think it was George Bernard Shaw who said "Sufficiently adavanced technology is indistinguishable from magic.".
The light goes off by magic.

OK I have a solution that'll take you seconds to see if thel light turned off when closing the door: Put you camera in the fridge, set it to take a picture after x number of seconds (no flash) and look at the picture!!!

despite being microsoft section, there is some sense in this question! what you one can do is try to close the door as close as possible still he can peep into the fridge. He he is lucky he can see light goes off and thus prove the lemma. other wise he can't conclude anything. But proving the converse is even difficult [he want to prove that light does not goes off even after doors closes]

Oh my god, in true avoid work style I just read the entire post on the fridge light on/off debate, and have come to the conclusion that despite it being logical to believe that the light does indeed go out, this may only be true to our need to believe that once we believe something it is true unless the circumstances change, but we often disregard the option that despite there being no change in causalities, the result could indeed change regardless, which would suggest that it is not possible for us to truly believe anything. So to mearly sustain the continued flow of human society the bulb does indeed go out, and disbelieving this is treason to humanity

Perhaps you should be more faithful in taking your medicine.  Humanity is not going to suffer greatly if you decide that events will turn out differently even though all the causes remain the same. To disbelieve all evidence and all common sense is hardly "treason against humanity". Instead, it is likely that only you and perhaps an unfortunate few around you who will be harmed by this sudden suspension of reason.
While it conceivable that the switch fails to work when pressed in by the door, though it does at other times, I think it far more likely that it will work and the light will be off.

Put a wireless sensor[Hi-fi answers for questions asked by a hi-fi company  ] inside the refrigerator that detects light.
Close the door of the refrigerator and find out the results.

Actually, there is no need to test.
No light bulb lasts forever. If you close the door, the light bulb will extinguish ... eventually.

There is a lightbulb in a Livermore, California firehouse that has been on for over 100 years (but not inside a refrigerator).
Looking through this thread, I noticed there are many answers being repeated as if nobody reads the previous posts- almost as bad as in the 100 Prisoners and a Lightbulb riddle. Is there something special about lightbulb questions that causes this?

Has anyone suggested using a camera or photographic film? What about a light sensor? Maybe put someone inside the fridge, or what about a plant?

Just ask Ya Hoody. He lives inside the fridge and it is his job to turn the light on and off.

In my opinion,
(1) Setup the refrigirator thermostat to room temperature.
(2) Close the door of refrigirator until the refrigirator's temperature will be same with room temperature. (Simply 1 day for sure)
(3) Open the door and touch the light burb to see
the heat. If the light burb was turned on while the door is closed, it must be hot. Otherwise it must be
similar with room temperature.

Average lifetime of a bulb is say X hrs. Keep the door open for X hrs till the bulb's lifetime expires.
Now by closing the fridge if we prove that the life time of the bulb is greater than X hrs then we cna prove that its switched off when we close the door

Statistics can be dangerous if not used carefully…
Ever heard of the statistician who drowned in a canal whose average depth was 15 cm?
Specifically, the average lifetime of bulbs gives only limited information regarding the lifetime of any single light bulb.

We already have more than a dozen answers for this. Here are three hundred more.
http://www.godlessgeeks.com/LINKS/GodProof.htm
Just replace the phrase "God's Existance" by the phrase "Light Gets Switched off when the door gets closed."
One of the typical (Well known) arguments (From Euler) is that
(a+bn)/n = x
And hence the light indeed gets switched off.

Assuming standard home sized unit. If we replace the standard bulb by (say)100 wattage unit bulb. Then measurements of power consumption before and after the door is closed should be the around unit consumption of the bulb.
Also If we can add an additional circuit, like XNOR gate
Door closed= True , Bulb off = True
Then
Door-Closed Bulb-Closed Power- ON
T T T
F F T
T F F
F T F
Power would only be supplied only when our considtions are met, and power off means no noise from the refrigerator.
