<p>PROBLEM TO BE SOLVED: To make adjustment more accurately. SOLUTION: When a body tilting angle of a vehicle brought to a standstill calculated from respective detection signals (a), (b) is different from the body tilting angle stored in a memory and the such different body tilting angle is continuously calculated in plural numbers, such different body tilting angle is superscribed on the memory and a set signal (c) corresponding to body tilting angle superscribed on the memory is outputted. As result, optical axial can be adjusted more accurately because when the body tilting angle of the vehicle brought to a standstill changes due to boarding or unboarding of passengers or loading or unloading of cargos, optical axes of head lights RH/LH can be controlled by following such changes.</p> |
