ABSTRACT:
An improved night light structure is arranged to be received directly in an electrical wall outlet and supported by the plug blades received in the outlet socket. The night light itself includes a capacitor in series with a miniature light bulb such that the voltage from the outlet is dropped in value by the capacitor so that the voltage across the bulb is substantially less than its normal voltage rating. As a result, the bulb can last for long periods in excess of ten years. Further, by utilizing a miniature bulb of relatively small voltage rating, should the capacitor short circuit, the bulb will immediately burn out and thus function as a fuse. A fail-safe night light is thus provided.
