hey whats going on guys... Im about to be the new owner of a '11 Denali HD as soon as I get back from Iraq, and was looking into lighting upgrades. I was looking to put HID's in it for sure, and wanted to know if anyone has done a retrofit yet? Also, has anyone thought about doing a whistler type mod to these headlights (if you can get them apart?)

 

ddmtuning.com along with many others sell hid bulbs and ballasts...
