I read threads about visibility, nighttime commuting, lights, and reflectors, but I haven't seen one about LED Reflective Safety Vests so I'll start one.
I need to leave the house around 5:30 AM so it's dark outside. And once fall/winter rolls around, it will be dark coming home, too. I found this LED Reflective Safety Vest to be quite helpful in the visibility dept. And I can also double as a Cal-Trans worker.
