Do those still have the button on the driver's side light to release the tailgate? Yours actually probably doesn't have, hmmm? I believe it's the limited trim and up that does.
Those tail lights look much better over stock. Do you think you might do a light tint on them later on? 3 weeks ago, I installed Coplus Infinite Series Bi-LED Headlights w/ LED DRL on my 2016 Colorado. They're very nice! Unfortunately, there aren't any LED tail lights out I care for on these trucks...medium tint for now.
