Yeah, they only claim a 2% to 4% improvement in fuel economy, not very noticeable on most commuter cars or especially low mpg vans and trucks, but it adds up quick on OTR tractor/trailer rigs running over 100000 miles a year.
If it were my van, I'd run the column straight up from the front edge of that side marker light, about as many as I could fit without spacing them too close together. Of course it isn't mine, so do as you see fit.
