These are simple yet wonderful design for the outdoor staircase no more tripping in the dark.

These cool new miniature Solar Deck Lights ($25) add accent lighting to your deck, steps and pathways using the power of the sun. On sunny days, the solar cells collect and store the sun's free energy into an included rechargeable NiMH battery. When the sun sets, the 4 super-bright LEDs activate to cast a circle of gentle illumination for about 5 hours on a full charge. A very sleek cord-free lighting solution. (via Michael Kiely)

In a world gone GREEN, these babies light the way to a cleaner Earth. Recharging their battery with the sun all day they give you great bright accent light and pathway illumination for about 6 hours when fully charged. Plus they look cool, not your typical box lantern design.
