Led Armbands for Running, 2 Pack Running Lights for Runners Rechargeable Reflective Running Gear, High Visibility Light Up Armbands for Night Running, Cycling, Dog Walking, Walkers, Pet Owners

Very effective

These are brightest at the ends, one of which gets covered up when in use, and not very bright through the middle section.Also unfortunately these don't use usb-c

I got these to try as I am out in the countryside with only a few street lights. They are very visible in dark, so fantastic for helping to keep me and my dog safe and visible when out walking out in the dark.Charging the light bands is quick and easy by using the supplied USB charging cable, a single charge lasts for about 6 hours for allows me to use them twice a day with out having to recharge after every walk. As you can see in the photos, they light up red when charging and go green when full.You have the choice of 3 lighting modes, fast flash, slow flash and constant light. I use the constant light mode, as it seems to stand out the most for what i need them for.They seem to be made of a quality material and are skin-friendly with them having a soft inner. I find them very lightweight and seem light rainproof. (DO NOT wash the bands in water directly tho)They measure 35.5cm x 3.7cm, so easy to take where ever you want.Overall they are fantastic bands and value for money. I may even order some more to keep in the dog van, I would highly recommend :)

Quite large in diameter, and can defo strap around hands, leg or attach to something. Glow is strong with few options. Cables included
