Lemon-Lime NightLight LED Collar: Reviewer: Karen Hazelrigg and Nico I received my nightlight LED collar in lemon/lime yesterday. We used it for the first time last night. Wow!!! Is it ever bright! I no longer have to worry that my black dog will not be seen once the sun goes down. Thanks so much for a great product. It was all I hoped for, and more. We give it 5 paws up.
