Yokomo SD-L7C 7-Color LED Module for Receiver Power  [SD-L7C]

Automatic 7-color LED for scale models

The SD-L7C is designed to add multi-colour lighting to scale RC vehicles, automatically cycling seven colours when connected to a DC 4.8V-7.2V supply such as a receiver BEC. It is aimed at low-voltage model electronics and provides a straightforward visual enhancement without extra controllers.

An extra connector is provided so you can chain two SD-L7C units together for broader lighting coverage or matched effects. Fitting is direct: attach the module to the receiver power output or a suitable external BEC, check polarity, and secure the board with double-sided tape or small screws if mounting points exist. This component is intended solely for R/C model use and must not be used with high-voltage or full-size vehicle systems.

The SD-L7C is chiefly for cosmetic and visibility uses and does not require setup. Keep in mind that enclosure choice and placement will alter perceived colour balance and brightness, so try the position before final installation.
