So this came up in another thread so I thought I'd start a new one. The one thing I'm really not impressed with on my 2015 Yukon SLT is the halogen headlights. I'm wanting to upgrade to the HID's but don't wanna shell out the $ to buy the Denali lights from GM. When I had a Pontiac G8 I dropped in a DDM tuning HID kit in the stock projector housings and it looked really good. Can that be done on these trucks or is a new housing assembly required? I know on other brands that offer HID and halogen lights on the same model the projector housings are actually the same and I'm wondering if that's the case here.
