I'm confused about this post.
I have a 2016 28DS and it has the single round headlights on each side. I'm pretty sure they are already Xenon HIDs, right? Or are they just halogens posing as HIDs? They look the same as the Xenon HIDs on our cars, minus the on the fly adjustments they make when you go up hill or make turns. I've never noticed our 28DS's lights moving when you go around a corner or make a turn.
