Maybe they're "driving lights" for filling in the gap on the near side of the main beams? Both my Tahoe and Sequoia have white driving lights mounted low in the facia, controlled by a separate switch. Yellow fog lights would get used a few times a year here but the white driving lights are quite nice to have all the time. I like to aim them to the sides to help illuminate deer eyes on the roadside but below the low beams so they aren't a nuisance to others.
