A light assembly includes a carrier. A first high beam light module is rotatably attached to the carrier for rotation relative to the carrier about a first high beam horizontal axis. A first low beam light module is rotatably attached to the carrier for rotation relative to the carrier about a first low beam horizontal axis. The first high beam horizontal axis and the first low beam horizontal axis are parallel with each other. A bar interconnects the first high beam light module and the first low beam light module. An adjustment drive is coupled to the bar. The adjustment drive is operable to move the bar along a bar axis. Movement of the bar along the bar axis simultaneously rotates the first high beam light module about the first high beam horizontal axis, and the first low beam light module about the first low beam horizontal axis.
