The LED dog leash is the latest innovation in pet safety and fashion brought to you by Dog-E-Glow. There is nothing else on the market like a Dog-E-Glow lead. Our products are truly one of a kind, combining high quality materials with catchy, fun designs and the functionality of bright LED lights. Our leads are made of high quality nylon sewn around several highly-efficient (100,000 hour) LED bulbs. The lights are only visible when turned on, either in steady glow or flashing mode. Dog-E-Glow collars and leashes are lightweight, highly durable, fully weather-resistant, and visible up to 1000 feet in the dark. Batteries are easily replaceable after 150 hours of LED use. Unlike other lighted dog leashes on the market, Dog-E-Glow collars look great as normal leashes too! They allow others to easily spot you and your dog from a distance when it is dark outside. With an LED dog collar you can easily see where your dog is at all times. Hiking, camping, tailgating, biking, or just in the front yard, there are numerous situations when keeping track of your dog at night comes in handy. Combining them with our LED leashes is perfect way to keep your dog visible to you, other people, and cars at night or times of low visibility. Collars are available in Medium (10 ? 15 inch neck size) and Large (15 ? 21 inch neck size). Leashes are 6 feet long.
