Miniature replacement bulbs come in a variety of shapes, sizes, and styles. Most of the bulbs are readily interchangeable between manufacturers. While the LED replacement bulbs will fit most of the standard sockets, they do require DC power. The key point for replacement bulbs is the body and socket style. The most common replacement bulbs include: Pea (or round) screw base: Candle body (or candlestick) screw base; screw base flame tip; and bi-pin or wire terminal (direct plug-in style). We primarily carry 12-volt miniature replacement bulbs manufactured by: CR2S; Cir-Kit Concepts; Miniature House; and Houseworks. The LED bulbs are also available in several combination of high/low intensity, pure/warm white, and flicker options.
