A lighting control system is disclosed. The lighting control system is electrically coupled to a load circuit for controlling indoor and/or outdoor lighting. The lighting control system includes a control module with a night light for providing low-level night light illumination and one or more sensors for operatively controlling the indoor and/or outdoor lighting and the night light in response to measured light levels and/or detected motion. The system is preferably configured to provide low-level night light from the night light when measured light levels and detected motion are below threshold values and to automatically turn on the indoor and/or outdoor lighting and simultaneously turn off the night light when measured light levels and detected motion are above the threshold values.
