TWO DIME-SIZED lithium watch batteries provide 70 to 100 hrs. of directed work light from the crown of the Head-Lite G2 cap. The cap's light-emitting diode (LED), which is molded into the crown, throws a 40-ft. beam to light your way. Unlike strap-on headlights, the LED is so lightweight that you won't notice its weight when wearing the cap.
The Head-Lite G2 adjustable cap costs $21.95, plus shipping, direct from the company. Various solid colors and camouflage patterns are available.
