Snow Peak Lapel Torch
Let's see: you need both hands to do an activity, you can't mount a light anywhere nearby, and you'd like to avoid the dorkiness of a head-mounted solution. Sounds like you need the Snow Peak Lapel Torch ($60). This compact, water-resistant LED light uses a magnetic clip to attach to pretty much anything — a shirt, a backpack strap, you name it — and is powered by a remote battery pack that connects via a 28-inch cord and can provide up to 140 hours of light.
