ABSTRACT:
A lighting system for use in a vehicle cabin comprises a step lamp arranged to a door, a foot lamp arranged to a seat and a seat lamp arranged to a roof. An ON-OFF circuit turns on the step, foot and seat lamps when the door is opened, and turns off these lamps when the door is closed. An arithmetic circuit controls the step, foot and seat lamps in luminance to obtain a gradual increase in brightness in order of the road and step, the floor and the seat.
