An apparatus and method for controlling a headlight system. The apparatus includes a control yoke control unit having a brake control, a dimmer switch, an actuating mechanism, and at least one control support for supporting the brake control and dimmer switch. Both controls are incorporated into the control unit. The control unit may have only a single control support with both controls therein, or it may have two control supports each with one control. The control unit also includes an electrical connector for connecting the dimmer switch to a headlight and a source of electrical power. The actuating mechanism is movable in first and second directions from a neutral position, such that moving the actuating mechanism from the neutral position in the first direction actuates the brake control, and moving the actuating mechanism from the neutral position in the second direction actuates the dimmer switch.
