Running lighting and reflection for women
Although it's not mandatory to wear a reflective vest and running lighting while running, it's very wise if you're heading out in the dark. As a runner you're quite vulnerable among fast cars and cyclists, so heading out well lit makes you clearly visible and therefore better protected.
Run safely
The biggest advantage of heading out well lit is of course that you're clearly visible to other road users and therefore much less vulnerable than if you run unlit.
Run undisturbed
When you think of a reflective vest, you might picture that big safety vest you keep in your car, but reflective vests for runners have a much better fit and sit much more comfortably. Running reflective vests usually have an X shape and can be adjusted with velcro.
