Judging from the color of the NT would bet it is a European accessory for the Deauville. A very clean installation for sure. I like it too.
Most of us here added Denali's on the front fender or cowl.
Another downside to those lights is that they're fog lights. I put the fog light lens in my Denali D1s for a couple of nights just to see the difference -- nowhere near as focused.
