A vehicular headlamp which includes an inclination measuring unit provided between an aiming screw and the reference member of the headlamp (the lamp body in the case of a movable reflector type headlamp and the lamp housing in the case of a movable unit type headlamp), which is simple in construction and easy to adjust. The inclination measuring unit is provided between the reference member and a straight portion on a rear end portion of the aiming screw, which is threadably engaged with the reference member. The inclination measuring unit includes a guide member extending substantially parallel to the aiming screw, a slide member supported on the straight portion and slidably coupled to the guide member, and a scale provided on the guide member or slide member for indicating an amount of displacement of the inclination member, thereby to measure the inclination of the latter.
