The ORACLE ColorSHIFT Halo Kit for GMC Denali (2000–2006) includes the BC1 Bluetooth controller, enabling smartphone control for colors, patterns, brightness, strobe, and music-synced effects. The kit provides a connected lighting upgrade for the headlight rings. The bright 3-chip 5050 SMD rings are built on a CAD-designed 6-layer PCB, consume little power, and install easily with pre-applied 3M adhesive; the BC1 offers four waterproof outputs for linking additional lights.
