I have a Hunters Safety System, and you can easily put it on in the dark. If you don't have one, get one. They are $100, and yes that seems like a lot of money, but if you happen to fall, what's $100? I have a wife and 2 boys and if $100 is all that stands between me and getting home, I'll buy 3 of them. These are just my thoughts and not to try and get anyone to buy one but there are a few other full body harness. out there. Why chance it over $50 - $100?
