Nite Ize - GlowStreak LED Ball These are no ordinary dog toys. Innovative, unique, and stimulating, the GlowStreak LED Ball is the most technologically advanced nighttime fetch ball ever made, and holds up to the best arm or ball launchers around. Great for lawn, park and beach games - get ready for endless hours of day or nighttime entertainment for both dog and human. This robust rubber ball has a protected inner core that contains an advanced motion-activated LED module with bright red or color-changing Disc-O LEDs, and it turns on with a simple bounce. It also features an auto shut-off function after ten minutes without a bounce (5 minutes of glow followed by 5 minutes of flashing), giving you or your dog time to find it if one of you becomes distracted. Classic dog games meet twenty-first century technologies with the GlowStreak LED Ball. The molded, shockproof, removable polycarbonate core houses the LED/battery module and screws securely into place creating a waterproof seal. The same size as a tennis ball and invincible to water or slobber, this tough little ball floats, and is great for the dog who loves to swim. The unique grooved design on the surface creates a bite friendly exterior that is easy to pick up for small and large dogs alike, making it the perfect fetch ball for your four legged friends of all sizes. Powered by replaceable, long-lasting batteries, you can have up to 35 hours of playtime with the GlowStreak - ideal for the ball-obsessed dog who wants to fetch for hours into the night.
