The ORACLE ColorSHIFT Halo Kit for GMC Denali (2000–2006) includes the ColorSHIFT 2.0 controller to let you select colors and adjust brightness for the headlight rings. It upgrades your Denali with configurable halo lighting and simple controller-based operation. The halos use 3-chip 5050 SMD LEDs on a CAD-designed 6-layer PCB for rigidity, draw minimal power, and mount to the headlight housing with pre-applied 3M tape.
