It takes surprisingly little light to walk at night. The key is to let your eyes become fully dark adapted. When walking on a decent trail, your feet will tell you whether you are on the tread or whether you have strayed of the path. With a full moon, or close, a light is often not necessary at all. Save the bright light for the rare occasion when it will be necessary; that is one of the virtues of lights with multiple levels. You will find that a headlight is best, but you will usually hold it in your hands so that its shadows will highlight the relief in front of you. It will need to be a headlight when you use your hands, but that is much better than sticking the light in your mouth....

Of course, by necessity, I developed night walking techniques back in the days when there was no alternative to dim lights.
