The NU05 v2 quad LED signal light is the perfect blend of style and function with two bright white LEDs and two red LEDs. The dual white LEDs can be activated for a 40 lumen max with constant on mode as a simple flashlight or headlamp, or flashing mode as a simple signal. The dual red LEDs can be activated on slow flashing or fast flashing modes depending on your speed or visibility conditions. The ultra lightweight NU05 v2 with its sturdy rear clip can be attached to bags, caps, cats, or belts and of course, can be used with the included strap as a rudimentary headband, or wrist light. The perfect companion for walks, runs, jogs, or midnight excursions.
