The days of the lamp are coming to an end.  LEDs are beginning their march to turn regular things into sources of light.  And the next step in that march of lite up generally dark stuff is the brick!

 

Sun Bricks are the size of standard modular paver bricks, and can be placed in a walkway alongside ordinary pavers to provide walkway illumination. The brick includes a solar cell to charge two AAA batteries which then provide power to two LEDs for up to 8 hours of nighttime lighting. They are completely self-contained and need no external wiring, so it's a simple fix to add in some solar-powered lighting to any walkway.  Of course, at $59 a piece it's not as cheap a fix as we might hope for.
