A plurality of lamps to 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 to inclusive is controlled in PWM fashion to restrict an amount of voltage supplied thereto. A current detect circuit portion solely detects all of the voltages supplied to the lamps to 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 to inclusive in a vehicular lamp control apparatus in which the lamps to inclusive are supplied with voltage from a high voltage battery

A sensor for detecting rotational movement includes a cylindrical shaped resonator having an outer surface, a first pair of diametrically opposed driving electrodes provided on the outer surface of the resonator, a second pair of diametrically opposed driving electrodes provided on the outer surface of the resonator, a device for generating concurrently a first force and a second force at each of the first driving electrodes and each of the second driving electrodes, respectively, in such a manner that the first force reverses its direction along the radius of the resonator at a regular interval, the second force reverses its direction along the radius of the resonator at a regular interval, and the direction of the first force is opposite to the direction of the second force.
