Hi everyone. This is my first post so forgive me if this has been asked. I got my wife a 2015 Yukon XL SLT w/ 4wd and tow package when they were just getting them on the lot. Needless to say, I probably paid what a similarly equipped Denali is going out the door for now. I don't regret not getting a Denali or want a Denali grill but the lack of HIDs bugs me. My car has them and when I get in the Yukon at night, I feel blind. My question is this-why is there not a direct swap from the Denali? Is it just b/c going aftermarket is cheaper? I was just wondering if I could swap out bulbs/relays etc or something or if it would be ridiculously complicated.
