I'm doing some night/glow runs in the Boston area and thought I should make some additions to my running shirt using an EL Panel.
An EL panel is a flat piece of luminescent material about 4"X4". If you print a negative image on a sheet of acetate (basically one of those old transparency sheets they used to use for overhead projectors) and glue it to the panel you can block out sections of the light to make a design. The panel is then attached to the shirt using Velcro.
Still running. Even if times seem dark.
