I haven't paid attention on the newest body style Denalis, but a few years ago they had all LED lights, except for the license plate lights.It's hard to believe that in this day and age that you would have halogen bulbs anywhere on a $70k truck, but I guess it's not all that bad considering you can spend over $60k on a Jeep Wrangler and have to select LED lights as a $1300.00 option
