I do usually write at night. But I use my headlamp on its lowest setting. I just know these things are going to come in handy for something. I'm going to bring them as they are so light their impact will be negligible.

I think they are absolutely perfect for the reason you first introduced them. No velcro to hassle with having to clean. Just wrap around your pant and off you go.  [smiley=thumbup.gif]
