Light sources (33a, 33b, 33c, 33d) disposed at intervals in the front-rear direction of a vehicle are provided respectively to reading lamps (25, 27, 29, 31) corresponding to second-row seats (7, 9) of the vehicle and third-row seats (11) of the vehicle. A lighting pattern including the brightness of each of the light sources (33a, 33b, 33c, 33d) is determined in accordance with a sliding position of each seat in the front-rear direction of the vehicle. As a result, the light sources (33a, 33b, 33c, 33d) are appropriately lit such that the brightness of the reading lamps is sufficient for passengers seated in the seats, irrespective of whether the sliding positions of respective seats are front leaning or rear leaning, thereby enabling appropriate illumination for seated passengers in accordance with variation in seating position.
