Mighty Bright XtraFlex2 Clip-On Light
It may not be the most attractive clip-on light, and I can’t imagine why the manufacturer decided to produce it in black, purple, pink, and silver but not off-white. Still, at $20 it’s cheaper than the e-Luminator2 from M-Edge. And unlike the e-Luminator2, this one will work without a case.

The Kandle is a compact light that’s made to blend in as much as it can with the Kindle. It’s a little chubby, but at least there’s not a huge gooseneck sticking out as with other lamp attachments. Several customers over on Kindleboards.com seem to really like it.
This light has a bendy neck and comes in off-white plastic so it matches your Kindle. There’s no clip, so you’ll have to use it in combination with a case. Note that this is designed for use with M-Edge cases and may not stay in position properly on other brands.
