Review on 🏃 Enhance Your Nighttime Running Experience with Adjustable Pivoting Chest Running Light for Runners & Joggers - Ideal for Early Morning Runs, Jogs, Dog Walking, Camping, and Hiking by Jeff Payne

I've been using them for my morning runs in the dark for a few weeks now. That's great light. There's a light mode and a dark mode, and I find dim is enough for reasonable viewing. The brightness is super bright. The light is tiltable so you can project it further forward or straight ahead. There's a slow red flash on the back that I'm told can be seen from afar. The strap also has reflective stripes. The strap fits my small figure (xs ladies) well and has grown a lot. Comfortable to wear. Charging is very fast if you connect it to a computer with the included USB cable. In dim mode, it easily lasted 5 hours. (You can see how much charge is left on the back.) I like this more than a headlamp because headlamps always slip on the head or are uncomfortable. Highly recommended!
