Keep track of your dog with this flashing device.

The Beacon by Ruffwear is a must if you and your dog maintain an active lifestyle and spend a lot of time outdoors. Equipped with a high-intensity LED light, this accessory clips on to collars, packs, apparel, life jackets and harnesses. Choose from three modes — slow flash, fast flash and always on — so that your dog is visible in low-light conditions. Whether you're out for a late night hike or walking the beach at dusk, you won't lose sight of your four-legged buddy.
