Custom Dynamics — turn signal decoder

The Custom Dynamics Turn Signal Decoder is an essential solution for modern Harley-Davidson Touring models equipped with CAN-bus technology. This compact, plug-and-play module solves a critical wiring challenge: on 2014-2025 generation models, turn and brake functions share the same rear wire, making it impossible to add independent amber or red turn signal functions without this decoder.

This decoder breaks out the left and right turn signal wires, allowing you to install advanced aftermarket lighting such as dual-color Plasma Rods, LED Plate Frames with amber turn signals, or custom LED turn signal assemblies. The module comes complete with all necessary hardware for seamless installation.

Perfect for riders who want to enhance their motorcycle's visibility and styling without compromising functionality or reliability.

Designed specifically for add-on LED turn signals, this decoder maintains factory compatibility while opening up endless customization possibilities. Its compact dimensions (2" x 1.4" x 0.4") make it easy to mount discreetly anywhere on your touring bike.
