    摘要: A plurality of lamps 21 to 28 inclusive are supplied with a voltage one after another in sequence. A time duration during which the voltage is supplied to each of the lamps 21 to 28 inclusive is controlled in PWM fashion to restrict an amount of voltage supplied thereto. A current detect circuit portion 36 solely detects all of the voltages supplied to the lamps 21 to 28 inclusive, respectively. Each of the voltages exceeds a threshold value, a dead band between two adjacent voltage supply durations. Thus, it is possible to restrict possible electromagnetic noises which are generated upon voltage supply to lamps 21 to 28 inclusive in a vehicular lamp control apparatus in which the lamps 21 to 28 inclusive are supplied with voltage from a high voltage battery 11.
