The ORACLE ColorSHIFT DRL kit for 2014-2015 GMC Sierra replaces the stock DRL circuit boards so you can change DRL colors while retaining factory headlight function. This Simple Controller option includes the direct-replacement PCBs and a basic ColorSHIFT control for wireless selection of colors, patterns, brightness, and speed. The kit fits Sierra models that already have daytime running lights and provides the components needed for the upgrade.
