Abstract
An alerting apparatus includes a pair of separate first and second lights capable of providing respective illuminations that are different from one another, an electrical power supply cord connected to the first and second lights for providing a supply of electrical power to activate the lights, and a motion detector connected to the electrical power supply cord and the first and second lights for activating the first and second lights for predetermined times in response to sensing motion in a predetermined area. The first light can provide a constant white illumination, while the second light can provide a flashing red illumination. Also, an alarm can be connected to the motion detector and the electrical power supply.
