I also picked up a new 2015 GMC Sierra SLT yesterday and in looking at the headlight configuration at the dealership thought "wow, this is gonna be just like my Escalade", but was I ever surprised when I went into town after dark. These can not be up to standards. I was very disappointed. Thought my old Ford was bad but these take the cake for being under lumen'ed! Hope there is a fix forthcoming. Subscribed.
