Changes

* There is no flashing light at the back. I simply purchased some cheap clip-on flashing safety lights which are cheap and effective.

* You can't use a waist mounted light to look at your watch, though most running watches have a backlight. It's also harder to use a waist mounted light to rummage through a drop bag, though I found I can hoist the Light Built up around my chest and pointed down and it works pretty well.

The Sprinter is my top pick for head mounted lights, available at <jfs id="B01LE9ZA28" nonl="true" noreferb="true"/>.
