Review on Stay Safe And Visible Anytime With GPMTER Ultra Bright USB Rechargeable Bike Tail Light - Perfect For Road And Mountain Bikes by Jonathan Roloff

I purchased these lights because I commute about three miles on foot per day next to very busy streets and wanted to stay as visible as possible. These fit the bill perfectly. The rubber straps made them easy to attach to my backpack, the button is conveniently located for easy use, and the lights are extremely bright. And the fact that they have a charging light indicator for when they are don't charging is definitely a plus.
