Welp. I was looking in relative cam on the gauges on the Wendover when I found this... Being the nerd that I am, This is a reference to Buick and their Auto headlight system from the 80's, 90's and early 2000's. Daddy Doug talked about this in the Buick Reatta (and/or) Cadillac Allante videos. I remember him saying it sounded like a romance movie.
