Before we get into a huge argument on who's philosophy of going vegetarian is better...
To my knowledge, there's no lighted cover (like Amazon's) where it draws power from the Kindle using those hooks.
BUT there are alternatives. I know that M-Edge makes pretty good covers (From various reviews). They have various jackets that are not made of leather. They also come with a little sliver where you can put the M-Edge light in there... So if you get the jacket + the light, you have a lighted cover.
The advantage to having a separate light is that you have a separate battery and you can detach it whenever you want.
Hope this helps
