There’s no end to the uses you’ll find for this adult version of the glow stick your kids love for their after-dark escapades. With bright visibility in every direction and 5 fun modes (color-changing Disc-o, green, blue, red and flashing red) it’ll liven up your nightlife and catch the eye of every passerby. Put one on Ol’ Pal’s harness during an evening walk, hang a bunch from their built-in S-biners to light up a party, or hang it on the privy to guide your way on a late-night nature break. No chemicals or batteries needed, the LED Glow Stick runs for up to 8½ hours on a single charge. It’s even waterproof, for those times when your nightly jog turns into a rain-soaked slog.
