A lot of chatter in here, but I was unable to stumble across the answer I was looking for. I have a friend who has a 2018 3500 Sierra Denali with the stock HID headlights. The problem is that his stock HID headlights are abysmal to say the least. Has anyone gone through the effort of upgrading these units? Results? I apologize in advance if this has already been discussed, but before I crack these bad boys open I would like to see what other solutions have been explored.
