A dog leash with a light bulb is hardly useful in a city where the streets are lit in the evenings and the animal is noticeable. But if you are going to walk with the dog through the countryside to the nearest hazel-nut, it is better to wear such a leash on it. Inside the leash there is a small generator, from which the batteries are charged, which in turn feed the LEDs. The leash is not heavier than traditional models and is covered with reflective film, the handle is also equipped with reflective panels. Unfortunately, while the collar is not on sale, but the manufacturer, the company Fido Fashions "in six months will finish the manufacture of industrial design" and "looking for several small investors to implement the idea."
