Ok so far
Bought these for 2013 Avalanche. Install was a breeze along with new Luxx series headlights. I think they look good and changing colors of lights works as advertised
These lights install super easy. They are perfect in the fact that they come with digital instructions which make it super easy. My one and only gripe with them is the blinkers are not serviceable. So once it goes out, you are stuck with buying another set if they are out of warranty. This is why I bought them this time (the set on my truck were there when I purchased it). So I replaced them with another set of AlpaRex lights. Otherwise these seem to be decent lights.
They do not illuminate anything
No dislikes here... I love these tailights! Super clean!
