Review on Rechargeable LED Chest Light Back Warning Light by ALOVECO - Ideal for Night Running, Camping, Hiking, Jogging, and Outdoor Adventures - 4 Lighting Modes with 90° Adjustable Beam by Gabriel Salleh

Amazing light. I strongly recommend running at night. Vehicles can recognize that I'm running a distance and they will slow down or give me time to pass. The chest piece that holds the bulbs allows you to adjust the brightness of both bulbs. I use the bulb on the left with constant brightness and turn the bib down, which provides enough light so passing cars aren't suddenly blinded by the light. At first I was a little confused about how to wear the light, but once I figured it out everything was perfect.
