Although it's bulkier than we prefer armbands to be, Armpocket's Nighthawk Armband with LED Lights ($50) is somewhat intriguing. It's compatible with all iPhones, and is large enough to support handsets in small cases. It has multiple compartments for holding accessories such as keys or headphones, and allows full access to touch controls. The most interesting component is the pair of LED lights, which will help keep runners safe at night.
