This LED light module is an RC-scale accessory that cycles through seven colors automatically when connected to a DC 4.8V–7.2V supply such as a receiver BEC. The unit is designed for low-voltage model electronics and provides a simple way to add multi-color lighting to a scale car without extra controllers.
The kit includes an additional connector to allow two units to be connected in series for longer light runs or paired effects. Installation is straightforward: wire the module to the receiver power output or a compatible external BEC, observe polarity, and secure the board with double-sided tape or small screws if fitting to a pre-drilled mount. Avoid connecting to high-voltage sources or full-size vehicle systems, this item is intended for R/C model use only.
Functionally the SD-L7C is intended for aesthetic and visibility roles on a model, such as show lighting or low-light orientation. It does not require configuration or programming, but placement and the choice of housing can affect the perceived color mix and brightness, so test-fit before final mounting.
