Question...Answered!

Back in 2009 I asked:

Why does the refrigerator have a light, but not the freezer? Wtf? 

And today the folks over at Mentalfloss have finally given an answer:

Since consumers use the light in their refrigerator quite often, and therefore consider it a valuable feature, manufacturers can justify the cost of installing those lights much more easily than they can with freezer lights.

As for why consumers don’t value freezer lights very highly, the most popular explanation is that we simply don’t open our freezers as often as we do our fridges. And when you do open your freezer, you may be less likely to stand there for a few minutes surveying the options.

Thanks for (eventually) getting back to me, Mentalfloss!
