Is one allowed to carry around a flashlight or head lap on Shabbat in a camping area w an eruv?
If the flashlight was not left on from before shabbos it may not be moved, as it is muktza machmas gufo, since it has no use on shabbos. If the flashlight was left on from before shabbos, then it is controversial if it may be moved. please see the following post. https://dinonline.org/2013/09/22/moving-led-flashlight-on-shabbos/
