The SpotLit LED Collar Light is a fun and functional way to keep pets visible at night. Set in a lightweight stainless steel carabiner, it attaches quickly and securely to pet collars to keep your animals seen and safe at night. With Disc-O Select technology, you can choose from six different colours making it easier to keep track of multiple animals, or leave it cycling through the colour-changing Disc-O Mode. The long-lasting LED is bright enough to be seen from far away and keeps pets visible whether you're on a camping trip or walking in the city. Powered by two replaceable CR2016 batteries (included), this little light will keep going for over 20 hours.
