Abstract: A lighting system for preferentially illuminating the seating area of a mass-transit vehicle passenger compartment while minimizing the illumination of an aisle and of side windows of the vehicle. A lighting fixture is mounted in a cornice area of the vehicle above the seating area. The fixture includes an air duct extension panel having an outer edge that connects to a sidewall of the vehicle and extends horizontally inward over the seating area. An elongated lamp housing is integrally formed as a unitary piece with the air duct extension panel and is disposed along an inner edge of the extension panel opposite the outer edge. A face panel connects between a ceiling of the vehicle and the extension panel inner edge. The face panel spaces the lamp housing downward from the vehicle ceiling toward the seating area to maximize seating area illumination. The air duct extension panel spaces the lamp housing inwardly away from the sidewall and side windows to minimize side window illumination.
