Every dog has its day and now, every dog has its night with the rechargeable NiteDog LED collar cover. Weather-resistant, durable and low-profile, this flexible illuminated strip secures to most 1 in wide collars, leashes and harnesses with two micro hook and loop tabs. Its bright light-transmitting polymer core is powered by rechargeable Disc-O Select technology - choose from three selectable colors of green, blue or red, plus red flash and color-changing Disc-O mode. Housed in a high-quality plastic exterior, the cover measures 6.42 in (163 mm) long and features a passive-reflective paw + bone pattern for extra doggone fun. Recharging in 1.25 hrs via micro USB cable (not included), NiteDog brightens up virtually any collar, leash or harness to keep your pup seen, safe and shining.
