Yokomo SD-L7C Auto-change 7-Color LED Module for Receiver-Powered RC Lighting  [SD-L7C]

Receiver-fed 7-color LED module

The SD-L7C is a compact LED board for scale R/C lighting that automatically cycles seven colors when supplied with DC 4.8V-7.2V from a receiver BEC or compatible external supply. It is built for low-voltage model electronics and adds multi-color effects without the need for extra controllers.

The kit ships with an extra connector so two SD-L7C units can be linked in series for longer runs or paired effects. Installation is simple: connect to the receiver power output or an external BEC, respect polarity, and secure the board using double-sided tape or small screws if mounting to a pre-drilled plate. Do not connect to high-voltage sources or full-size vehicle electrical systems; this product is intended for R/C model use only.

Designed primarily for show lighting and improved visibility, the SD-L7C does not require programming. Final placement and any housing will influence perceived color blending and brightness, so trial-fit before permanent fixing.
