Abstract
An LED night-light includes a housing and first and second prongs extending out of the housing. A light-emitting diode is mounted to the housing and is configured to emit a first color of light. Circuitry is electrically connected to the light-emitting diode. The circuitry is configured for energizing the light-emitting diode when the first and second prongs are inserted into an electrical outlet connected to a power source. A color filter is mounted on the housing. The color filter is configured to filter the first color of light emitted from the light emitting diode to produce at least a second color of light different from the first color of light.
