Petzl Zipka:
The Zipka is essentially the same triple-LED light as the popular Petzl Tikka, but it features a roll-up strap instead of a headband, which gives you the versatility of attaching it to other places besides your head (like your wrist, ankle or pack). The strap design shaves six grams off the weight of the Zipka, so most of the 64 remaining grams consist of the three AAA batteries. This is a great light for day hikers, backpackers, campers and fly fishing folk who can't tie their tippets by the light of the moon.
