I have the same headlights, but smoked. I noticed a couple months ago that the thin, clear coating on the outside of the lens, is starting to flake near the top edge. I installed them in March of 2020. The clear on my black GMC grill emblem is doing the same, and also the top of the aftermarket rear spoiler with the full length smoked HMSL. They were all installed around the same time.
Anyway, these headlights have two plug connectors. One for the parking and turn signal, and one for the high/low headlights. The LED bar is spliced into the harness with the parking lights
