Review on Stay Safe and Visible While Running with RODH Led Safety Lights - USB Rechargeable and Adjustable Strap Included (1 Pack) by Steven Loy

Our mountain location does not have streetlights, so we could not walk with a flashlight after 5:30 in the winter without pain. This completely solves this problem and allows us to take the dog on long walks after dark. It easily illuminates an area maybe 20 feet wide and 20-30 feet ahead. It's so bright that I turn it off when we walk up to someone. The only improvement would be the inclusion of a front to back cord in the straps - this cord is a bit tight on my husband's frame.
