Anyone who's tried to fix something alone in the dark understands the value of a headlamp: Sometimes you need to work with both hands and have the light shining where you want it. The Vizion eLED Headlamp ($35) takes that good sense and makes it more sensible. Big buttons and knobs let the wearer click through three beam settings, including night-vision-saving red. Waterproof to 33 feet, the compact light is powered by three AAA batteries. A heatrecovery system keeps the LEDs cool and the batteries warm, optimizing the performance of both.
