Correction: not in your freezer. Mine has one.
Yup, false premise. My freezer has one too. We bought the fridge in 1993.
The premise isn’t false, it’s faulty. The OP just didn’t specify what refridgerator.
My 15 yr/old Hotpoint doesn’t have a light in the freezer, but it does in the fridge.
Peace,

Okay, okay. But all my life, growing up there was light in the fridge but not the freezer. I wanna know too now.
Note: Our new fridge does have a light in the freezer, but the freezer runs down the entire left side of the whole gizmo taking up a third of the whole unit.
Until I opened this thread, I was happy because, even though my freezer has no light in it, nobody else’s does either - or so I thought. But now I am bitter and envious instead :mad:
Side by sides typically are lit in both compartments. From what I’ve observed, bottom compt freezers are lit, too. Other than that, some top freezers are lit, but most aren’t.
Really? I would have expected bottom compartment freezers to not be lit. The one we have pulls out like a drawer, exposing the contents to the light of the kitchen – no need for any other light.
Side by side freezer and fridge here, both lit.
Cheapness. A cheap fridge doesn’t have a freezer light. A good one does.
Guess which kind I have. 
Growing up, my grandparents had an ancient Fridge-adaire (sp?) with a light in the freezer. I think they bought it new in the 40-50s and it was still running in the late 90s. Other than that, I’ve never had one.
Taking a wild guess, could it be because the fridge is low and has nooks and crannies that are hidden by food items while the freezer is eye level and has no “dark corners”? That, and cheapness.
Sorry people but even cheap ones sometimes have freezer lights.
All good refrigerators have freezer lights.
Some refrigerators do not have freezer lights.
Therefore, refrigerators which do not have freezer lights are cheap.
QED. 
Invalid. An expensive, but not good, refrigerator might not have a freezer light.
Then it is not good.
I run rings around you logically.
My side by side, lights in both, twelve year old refrigerator came with a trailer. It must be cheap by definition.
I burning your Frigidaire.
I always assumed it was because the temperature differential between the element and the ambient were more extreme in the freezer, hence likely to shatter.
A WAG I’d almost be willing to bet $1 on: until whenever, freezers frosted up like craaazy. When not crazy, they still frosted up. Ever put an ice cube on a light bulb (my inner-scientist-child did)? So, lights in feezers didn’t become part of standard manufacturing. Eventually, people started asking for them, and by then the technical problems were not an issue.
Doublechecking, lissener already got it. Damn.
Non-serious answer:
Because the stuff in the refrigerator might still be alive and moving, so you need a light to be able to catch it. The stuff in the freezer isn’t going anywhere.
Oh yeah? Ask someone who knows about catfish.
