What a neat contraption!

I bought this for my son to wear when he takes the dog out for a walk, it gets dark so early now and he always wears dark colored clothing. This is very adjustable and would fit almost anyone of any size (not the typical tiny sizes you expect from these things). The pictures I posted is on the lowest setting so I could take a photo of it on. Bright light to see ahead of you, and a red light in the back so others can see you.
This is a great safety tool for hiking, jogging, camping and fishing.
