I do both. Once a week I do a long ride around a century. These days all I do is try and be back on roads i know before dark. Getting lost with shorter run times on my headlight was annoying in the middle of nowhere. Now I have enough light time with me and back up headlight and tail lights. I have enough light to make it until dawn. That is very reassuring. I still bring a map and a compass. Been a long time since I have used either one. On new roads, at some intersections that I will be coming back through in the dark, I turn around in the day light and look at the intersection to be sure I can recognize it in the dark on the way home. Only been lost once this year, and, soon I found a road I knew for the way home.
