The ORACLE ColorSHIFT Halo Kit for GMC Denali (2007–2010) adds fully customizable LED rings to the factory headlight housings and includes a ColorSHIFT 2.0 controller for direct color and brightness control. It lets you pick whites from 3000K–15000K and dial in exact hues. These 3-chip 5050 SMD rings sit on a CAD-designed 6-layer PCB for rigidity, consume little power, and mount with pre-installed 3M adhesive backing.
