How come there is a light in my fridge..but not in my freezer?

Question

i was just wondering

Answer 1

Because you have an old/cheap refrigerator? I have a light in my freezer!

Answer 2

If you have the freezer open and the light is on it will heat up and expand. When you close the freezer and it switches off the temperature change is very big and the glass will break.  

Answer 3

Age old question my man, age old.

Damned if I know....  

Answer 4

Just a guess,

If the bulb filiment is frozen and it gets turned on when the door is opened then the filiment might fail due to the shock of the filiment getting hot very fast.
