Because candles just don't cut it...

From Slate.com via Kimbooktu (whose site I pretty much love):

“The sort of people who use book lights—book lighters, if you will—are not to be trusted. The device itself, remember, is intended for surreptitious reading. If these people have nothing to hide, why do they sneak off to a dark corner with their tiny, battery-operated lights? Why do they continue to read after their spouses have gone to sleep? What, exactly, are these book lighters planning?

I'm not sure, but I'm pretty sure it's something.”

Now, I was always more of the flashlight-under-the-covers persuasion, but some of these lights look pretty nifty. I especially like the over-the-ear one: good for reading while lying down, I suspect, and especially handy for when you need to transition quickly from reading to spelunking.
