摘要： An inventive headlight optical axis aiming measuring apparatus and method is disclosed. The apparatus includes a head measuring horizontal and vertical inclinations of a front lens surface (34) of a headlight (12) installed in a vehicle (2) and including a plurality of contact-type displacement sensors (48, 49, 50, 51), each of which is associated with a device (28, 29, 30) in contact with the front lens surface (34) and moving in accordance with the inclinations of the front lens surface (34), a support (15) for the displacement sensors (48, 49, 50, 51), and device for checking the headlight optical axis aiming in accordance with a fixed relationship between inclinations of a headlight optical axis and the front lens surface (34) by means of outputs of the measuring head (9). In accordance with this invention, the headlight need ot come on and a large space is not required for projecting the headlight beam onto a screen.
