PURPOSE: An aligning device is provided to align head lamps according to weight and location of passengers or loaded material. CONSTITUTION: Location sensors(10a,10b,10c,10d) are installed at both ends of a front bumper(100a) and a rear bumper(100b). Signals from the sensors are supplied to an ECU(electronic control unit)(20) for driving an actuator(30) adjusting irradiate angles of head lamps. Thus, change in the irradiate angles caused by inclination or overall height of a vehicle is automatically compensated. Herein, the location sensors use RF(radio frequency) sensors for measuring height of the vehicle through calculating returning time of electric wave from ground. Moreover, the measured values of the location sensors are independently supplied to the ECU.
