There aren't many head torches like the Bindi from Petzl. Not only is it lightweight and tiny, but it also produces 200 lumens. This makes it perfect for camping and a variety of other activities. You can use it for running through the city at night as well.
The head torch comes complete with a red and white LED. The white light has three different modes. The red light is particularly well suited for group activities, as it won't be as blinding to others as a white or yellow light would. You can wear the head torch around your neck or opt for the more unconventional option of wearing it around your neck.
