Review on USB Rechargeable LED Safety Lights (2 Pack) - Clip On Strobe Running Lights For Runners, Joggers, Walkers, Kids, Dogs, Bike Tail Light Reflective Gear Accessories by Dennis Wood

Easy to use, easy to recharge, and easy to see. I wear it like an epaulette so that it's more or less at eye level for motorists. However, as it's designed primarily for use facing either front or back, it would be better for my use if it had a higher dome so that it worked equally as well for both front and back. Otherwise, it would have 5 stars.And, at two for one price, I'm not paranoid about losing one or having one discharged, as there is a backup.
