ABSTRACT:
A nightlight including a light bank having light-emitting diodes (LEDs) disposed in an array. The amount of light emitted from the light bank can be varied by engaging a switch that selects between a number of electrical pathways. The device includes a photosensitive device such as a light dependent resistor or photo-diode for switching the device on or off under varying ambient light conditions. The photo-diode may be temporarily deactivated in bright ambient light conditions to check and change the settings of the LEDs.
