The motion-sensing light is triggered when someone or something enters its 1-2 meters range within a 120 degree sensing angle. A potential intruder could be scared away by the sudden burst of light. Or if you simply need a light after parking your car, this can function that way too. Note：The grid line permutation of the solar panel may have a slight difference, but it does not affect the product function.
