Illuminated Dog Leash, by Joseph Hassan. This colorful light-up leash can be seen from up to a quarter-mile in the dark. It’s made of reinforced nylon, so it’s strong and lightweight, plus a buck from every leash is donated to charity. There's no better way to light up your pup crawl. Pup Crawl Lights-Up Leash available in pink, orange, white, yellow, red, blue and green; 6ft/1.8m long. LED lights powered by two replaceable CR-2032 batteries (included).
