The GMC Sierra has two LED accent bars in the headlights. They are illuminated by circuit boards that hold white LEDs. Our replacement LED boards utilize RGBW LEDs instead! The RGB function allows for full multicolor control using any standard RGB controller, to accent the look of your Sierra and make it stand out on the road.
This product is not just RGB though- it is RGBW! That means there is an LED chip that is specifically white in color, right next to the standard red, green, and blue chips. By using an RGBW controller rather than the standard RGB, you can activate and control the white chip independently of the colors. This provides a much more uniform, pure, and bright white color than the traditional method of combining all RGB signals, so you can keep a clean, factory white appearance for everyday driving. With this setup, both LED bars will be on at the same time, instead of just one or the other.
You don't have to align and fasten LEDs by hand- this is an OEM-grade solution, with exact fitment, and perfect alignment of the new LEDs. Just remove the factory boards, and ours fit directly in place. Your order includes two sets of LED boards, one for each side.
To drive the high-power LEDs safely, a new constant-current, waterproof, inductive driver is included for each set. You will also need a standard RGB or RGBW controller. Controllers can usually be powered by any standard 12V source. We recommend connecting to the parking light signal, so this module lights up when the parking lights or headlights are on. Remember, when you're not showing off, you can set the LEDs to pure white for everyday use.
Professional installation is strongly recommended, as the factory headlights must be opened in order to replace the LED panels. Wiring instructions are included to identify the wire colors required to power your controller.
