The ORACLE ColorSHIFT Halo Kit for 2011–2015 Kia Optima includes the BC1 Bluetooth controller so you can pair a smartphone app, select millions of colors, control patterns, brightness, strobe, and even sync to music. The 3-chip 5050 SMD rings sit on a CAD-designed six-layer PCB for strong light output with low power use, and they mount using pre-applied 3M adhesive; triple halo kits add extra rings for turn signals.
