摘要： A light projecting angle adjusting apparatus for a vehicle headlamp, where the division voltage points of a resistor device, across which a supply voltage is applied, are selected one at a time, to provide different division voltages as set voltages. A division voltage provided by a reference resistor device across which the supply voltage is applied is defined as a reference voltage which is compared with the selected set voltage. An output signal is generated according to the result of comparison and the light projecting angle of the headlamp is adjusted to a value which is determined from the output signal.
