I felt Dean was safer when he wore the "Nite Dawg" orange LED collar on our evening walks. Instead of merely wearing a blinking light, this collar glowed orange, the entire way around his neck -- much easier to see. The collar kept him visible while crossing the busy streets of Baltimore and running around the park. Also, the collar is lightweight. At around $17.50, I'd definitely say this collar is a great buy for anyone who walks or plays with their dog at night.
