Mostly Harmless: interesting replacement headband idea for the Zebra Light. A few questions come to mind. Are you using a straight or angle head light? Are you using the cord lock to form a loop to hold the light and then tie the shoelace around you head? Or is it vice-versa? What kind of knot do you use and for which purpose? What length and width lace do you use? Do you mount the light at the side of your head or in front, on your forehead? I have the straight Zebra SC51. I'd like try your method out. Thanx in advance.
