One of our favorite gadgets this year is this incredibly compact and lightweight headlamp from Black Diamond Equipment. A headlamp to see and be seen should be in every runner and walker's kit, especially in the fall and winter. A solid headlamp lets you see where you're going, helping to avoid dangerous falls, and alerts your presence to other pedestrians, cyclists and drivers. Headlamps are also incredibly handy for household chores when hands-free lighting is a must.
What sets the Ion apart from the pack is its barely-there size (it's barely larger then the two AAA batteries that power it), high output (80 lumens) and button-free operation (like a smartphone or trackpad, you 'swipe' the face of the headlamp to turn on and off and rotate between white and red beams, solid and strobe modes.
