An improved motion detector head that includes a passive motion sensor with "test," "sensitivity" and "timer" adjustable functions, mounted inside an outer housing with two water-resistant touch-operated membrane switches used to control these settings. Also mounted on the sides of the outer housing and connected to the motion sensor are at least two bright LED lights designed to illuminate in one of three possible colors to visually indicate the current "test", "sensitivity" or "timer" setting of the motion detector.
