Abstract: The invention resides in an alert device, the device including a housing containing one or more flashing light sources and one or more non-flashing light sources, wherein both flashing and non-flashing light sources are arranged to emit light away from the housing, and optionally a detector adapted to detect the movement of an object into an area proximate to the housing, and control circuitry connected or connectable to a power supply, wherein the control circuitry is adapted to light the one or more flashing light sources in response to a signal from the detector indicating that a moving object has been detected.
