So I recently noticed that my Feb 2015 build Model S without premium lighting oddly has a light under the front passenger seat that provides light for the rear passenger footwell, however that light assembly is completely missing on the driver's side. I figure that I either got a free light that I shouldn't have, or that I'm missing a light that I should have. Question 1: Can someone confirm that one-sided lighting is not a "feature" and also whether I should or should not have the second light if I did not upgrade to premium lighting? Question 2: How does this happen? Is there a worker on each side of the car during assembly making independent decisions about whether the lit assembly should be pulled from the bin and one side messed this up?
