Overview

Added function. This harness was designed for use with Diode Dynamics 2015-2021 Subaru WRX/STi C-Light Switchback LED Boards ONLY. This harness allows your C-Lights to also function as the daytime running light. It will deactivate the factory daytime running light, and instead power the C-Light. Your high beam function will still work as normal.

Easy Installation. Using OEM connectors, this kit is 100% plug-and-play and installs in minutes.

Reliable Operation. This module has been designed with quality components, custom-tooled OEM-grade connectors, and includes embedded circuit protection, for high reliability over time. It is proudly assembled in St. Louis, Missouri by Diode Dynamics Manufacturing.
