Just adding my 2 cents on the Opt 7 kits. I've had the Opt 7 kit in my 2015 Sierra Denali since December 2015. I've never had any issues, have fired up every time. The only issue I had was the color of the bulb. I selected the 5000k 35 watt kit, and the bulb was always too blue for me. It doesn't match the LED top and bottom when headlights are on. For this reason I just ordered the Morimoto 4500k replacement bulbs from ebay. I'm hoping that will give me a closer match. This is the kit I ordered from Opt 7. http://www.ebay.com/itm/OPT7-Premium-AC-CANBUS-HID-Kit-9012-5000K-Bright-White-Xenon-Light-Conversion-/121599480127?hash=item1c4fe4d13f:g:HDAAAOSw-0xYZESV&vxp=mtr Also, the Morimoto replacement bulbs were $38 on ebay with free shipping. The retrofit source is just down the road from my office, but they are out of stock. I picked up the Morimoto LED fogs from there last year and they have been great, really add a lot of light.
