This Nightstick light is two tools in one: a bright 150-lumen flashlight for seeing in the dark, AND a safety beacon with white and red LEDs that can shine steady or alternate strobe. The top button controls the focused flashlight beam (momentary or constant on). The bottom button runs the safety lights: press once for steady white/red flood, press again for a flashing strobe pattern between the two colors. It's perfect for roadside emergencies, directing traffic, marking hazards, or camping. It comes with a removable magnetic clip (sticks to your car) and a lanyard ring. Powered by 4 AA batteries (included!). Durable, waterproof, and safety-tested for tough situations. A must-have for first responders, security, construction workers, or anyone who needs reliable light and visibility.
