starting a gradual light reduction of a first one of the plurality of lamps corresponding to said first one of the plurality of doors;
storing a value corresponding to a second one of the plurality of doors which is opened and generating a second door value indicative signal;
determining whether or not said first door value indicative signal is identical to said second door value indicative signal and generating a door value identical indicative signal when said first door value indicative signal is identical to said second door value indicative signal; and
continuing said gradual light reduction of said first one of the plurality of lamps when said door value identical indicative signal fails to be generated.
