9-LED lights? (I think I've seen those - the office supply stores sell them, too.)

I think they'd be a good idea. Then I won't need to carry a light - I'll just bask in the radiated light from the next campsite! smile

Seriously, though, I've used and been satisfied with the Princeton Tec Scout, Black Diamond Gizmo, and any of the Petzl Tikka/Zipka series. If you're an ultralight zealot, the Princeton Tec Pilot (Just-in-case) light and Petzl e-Lite are sufficient. My own favorite is the PT Scout, because in the straight-ahead (storage) mode, the on-off button tucks up under a little flange that prevents it from accidentally turning on in your pack.
