I had nothing but issues with the HID kits in the 15 Yukon. After spending almost $200 on the kit from kbcarstuff with Phillips bulbs and then shipping to replace defective parts, I gave up. I ended up going with Silverstars for a few months but missed the crisp white light.
I ended up saying eff it and ordered some fanless led lights. They use the factory plug and that's it. They fit in the headlight enclosure and work flawless. They aren't as bright as the HID, but they are as bright as the Silverstars and were $45 shipped. They are the leds that use the ribbons for cooling. In very happy now!
