This has also happened to me a lot since getting the truck... brought it in and dealership suggested turning off interior motion and it hasn't gone off since. Not really a "fix" in my opinion, but it will do for now.
I agree, when I first saw the tail lights on 21’s first impression was that they should have reversed them... higher trim models with less white.
But they have grown on me... hard to let that bother you too much when you get into this beautiful truck!
Definitely nothing crazy but I thought I would share. Since I like seeing what people are doing to their trucks... tint shop did a subtle 20% tint on just the white part of my tail lights today. I think it calms them down a bit wasn't a huge fan of all that white. Might not be for everyone, but...
I was told its a smoked paint protection film, which has a glossier finish than regular window tint, which matches the finish of the light better and makes it look closer to stock.
Our friends in Orangeville, Ontario have a series of a few "will it fit" videos... here is their video on the 2015-20 Borla exhaust.... with a little mod they make it work.
