Nite Ize Glowstreak LED Ball

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. This robust rubber ball has a protected inner core that contains an advanced motion-activated LED module with 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. The molded, shockproof, removable polycarbonate core houses the LED/battery module and screws securely into place creating a waterproof seal.

Waterproof- it floats!

Run time: 35 hours 2 replaceable CR2032 batteries included
