The ORACLE ColorSHIFT RGB+W DRL upgrade for 2020–2021 GMC Sierra 2500/3500 HD transforms factory LED DRLs into color-changing lights while keeping a true white OEM DRL option. The kit creates hundreds of colors, selectable patterns, and offers brightness and speed control via the included BC1 controller. Designed for models with the factory LED DRL option, installation requires headlight disassembly for proper fitment.
