The Karlie Visio Light USB band can be universally attached to a dog leash, collar, harness, or clothing. This is done easily and quickly with two Velcro fasteners. The silicone band is splash-proof and durable. Thanks to the three different lighting functions, both dog and owner are always clearly visible in twilight or poor visibility conditions with this accessory. The light band is charged via a USB connection, and a corresponding cable is included. Available in yellow and orange.
