New IllumiWrenches, never used.  Description from the manufacture:

This is the wrench set with built-in LEDs that provide directional light without wires, hot bulbs, or an assistant to hold a flashlight.  Powered by rechargeable batteries, recessed lights in the cradle of each wrench head come with high- and low-beam settings for precise viewing while working under car hoods, beneath sinks, and in dimly lit basements. 

With three hours of charging on the base, each wrench provides five hours of light apiece, ensuring illumination for the duration of a project. Made of chrome-plated, drop-forged steel. 

Seven double-sided wrenches from 3/8" (10mm) to 3/4" (20mm).  Recharging dock stands upright on a workbench or hangs on a shop wall. 10" H x 8" W x 2" D. (4 lbs.)
