No hunter should go out without at least one, and preferably two lights IMHO. A few years ago I went with a Princeton TEC headlamp that was around $40. I now have two of them, as I got a second one as a gift. They have 3 LED bulbs and by pressing the button you can set the light at 3 different intensity levels and a 4th level will blink like an emergency feature. Each one takes just 3 small AAA batteries and they last a long time. I carry a very small mag light in my pack as a backup and it very seldom comes out other than to make sure it's still working. Headlamps really come in handy when you are gutting an animal after dark and need both hands to do the job effectively and safely.
