This video goes over the installation steps for our LED Sidemarkers for the 2020+ GMC Sierra 2500/3500! These LED sidemarkers are a plug-and-play replacement for the factory fender lights, illuminating the entire width of the housing for a distinctive look.
We offer these in standard and sequential models in your choice of amber, clear, and smoked color options. Both the standard and sequential models feature a unique startup sequence. Every time the sidemarkers turn on, they illuminate in an intense amber color starting from the center then spreading to either side. Once they are completely illuminated, they gradually return to a running light mode. Our sequential option gives you added sequential turn signal functionality!
Diode Dynamics LED Sidemarkers for the 2020+ GMC Sierra HD are proudly assembled in the U.S.A, and are backed by a 3-year warranty.
