Abstract: The present invention relates to a LED battery-operated replacement light designed to removably insert into electrical openings in decorative fixtures/items. The light includes an interchangeable LED, a rechargeable battery, and a timer chip. The LED is coupled to the battery for electrical power and the timer chip is configured to store a timer value duration for which the LED remains illuminated. For securing the light in an opening, a metal retention biasing clip is provided that has a pair of tapered legs with graduated indentations such that the LED, battery, and timer chip are inserted along a perimeter of the opening, wherein the legs are initially pushed towards each other to insert along the perimeter of the opening and are then subsequently released for biasing the legs outward to secure the light inside the opening.
