Fetch up after-dark fun with the Nite Ize GlowStreak Rechargeable LED Ball. This ruff 'n tuff rubber ball features a protected inner core with an advanced motion-activated LED module. Featuring a color-changing Disc-O LED with a fun color-blending pattern, GlowStreak activates with a simple bounce to keep the fun bouncing from dawn to dark. It also features an auto shut-off function after ten minutes of inactivity (5 minutes of glow followed by 5 minutes of flashing), giving you and your pup time to find it if you get distracted. The molded shockproof core houses the removable LED module, screwing tightly into place for a waterproof seal. Also within the module is the rechargeable USB-C port, allowing you to quickly unscrew and recharge in 2 hours via USB-C cable (not included). About the same size as a tennis ball, GlowStreak stands up to water, slobber, and endless fetch sessions and even floats for fun-loving swimmers. The grooved surface creates a grippy bite-friendly exterior that
