The Oracle Lighting ColorSHIFT halo kit for GMC Terrain (2012–2013) ships without a controller, leaving you free to choose the ColorSHIFT option that suits your install. The bright 3-chip 5050 SMD rings mount to a CAD-designed six-layer PCB and attach with pre-applied 3M adhesive. This 12V kit is energy-efficient and can be wired to a switch, controller, or directly to parking/running lights for flexible use.
