Take your dog for a walk at night with your LED dog leash. Light up your way as you walk through the dark. Remain steady. Spot any obstacles along your path. Get some exercise. Not all dog parks are off the leash. Leash your dog as you walk around the park. Keep everyone safe. You can always research which parks are off leash for next time. Dogs can't use human toilets. The handle of your dog lead stores dog poop bags. Bag up their poop and place it in a bin. Do your civic duty. Don't worry about finding batteries for your LED dog lead each time. Just plug it into a USB charger. 70 minutes of charging for 5 hours of light. More than enough for a long evening stroll. Go handsfree with your dog lead. Loop the leash handle over your wrists. Pull out your phone to work out if you are truly lost. Flick through the various LED colours till you find one that matches your mood. Charge via USB. Use a wall charger, powerbank, laptop or other charging port.
