Abstract
A control device has a night light that allows the control device to be easily found when the control device is located in a dark space. The control device comprises a low-power night light circuit having an LED characterized by a normal current range. The night light circuit conducts an LED current through the LED in a first mode to illuminate the LED to a first level to provide a night light, where the LED current has a magnitude below the normal current range, such that the night light may be provided in a battery-powered remote control that has an acceptable battery lifetime. The night light circuit is configured to operate in a second mode to illuminate the LED to a second level greater than the first level to provide feedback. The LED current in the second mode has a magnitude within the normal current range of the LED.
