These glowing LED straps for walking or running increase may increase visibility during low light and night. Even jogging on a walking trail is not safe nowadays because distracted drivers often drive off of the road. Assuming that a driving is paying attention to the road and not their phone, these LED straps may make a runner or walker more visible at night. I wear one strap on my wrist and the other strap on my ankle. Alternatively, they could both be worn on wrists or both be worn on ankles. Two sets could be purchased to cover both ankles and both wrists. They’re convenient because they recharge using USB and battery life is several hours. Since I only walk for about one hour daily, I don’t have to recharge these LED straps daily. They work like the old slap bracelets from the past.
