This novel light, which can be worn around the neck, frees both hands. People who have difficulty using their hands can also use it. The silicone strap makes it easy to attach and detach. For safety, it is automatically detached if a load of 20 kg or more is applied. The original product, which earned the iF Product Gold Award in 2005, has been improved in the following areas: 1. The light block is now rainproof by enclosing it in silicone material. Battery replacement has been made easier. 2. The brightness has been increased to sixfold. 3. It can be switched on and off with the thumb.
