With the flashlight, flasher, and whistle features, these glow sticks aren't only entertaining to use at dark events like concerts or park outings, but they're also great safety aids. Kids can signal for help or be found with more ease when using one of these. Security guards, event staff, or campers can also use them for multiple purposes. These have an on/off switch so they’re reusable again and again. This multi-functioning GLOW Stick not only provides a long-lasting LED light, but also features four safety signaling modes, including: color glow stick, color flasher, bright white flashlight, and whistle.
