The SpotLit Rechargeable Collar Light gives you the extra eye and peace-of-mind you need while your dog explores the outdoors, from the backyard to the dog park to the campsite. Simply clip the light onto virtually any collar and give it a push to bring it to life. Featuring a Disc-O Tech LED module, you can leave the light in color-changing Disc-O mode, letting the vivid colors cycle through, or select from 4 colors of red, green, blue, or white, setting any of them to glow or flash. Its built-in memory feature remembers your last color setting, automatically turning back on in that setting for the next night of fun. With rapid recharging in 2 hours via micro USB cable (not included), you can charge up to full brightness and return to more adventures with your furry sidekick in clear view.
