The Oracle Lighting ColorSHIFT halo kit for GMC Sierra (2007–2013) ships without a controller so you can choose the ColorSHIFT option that fits your setup. 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 provides efficient, bright light output and can be wired to a switch, controller, or directly to parking/running lights.
