Abstract: A night-light is configured to emulate a traffic signal and thereby train a child to remain in bed during a predetermined interval. In accordance with one embodiment of the present invention, a night-light comprises a housing having a first light emitter (e.g., a red light source), a second light emitter (e.g., a green light source), a controller electrically coupled to the first light emitter and the second light emitter, and a timer interface electrically coupled to the controller, wherein the controller is configured to operate in a first, second, and a third mode. In general, the first mode corresponds to the first light emitter being activated (“bed-time” mode), the second mode corresponds to the second light emitter being activated (“wake-time” mode), and the third mode corresponds to the case where neither the first or second light emitters are activated (“off” mode).
