Headlamp aiming tool and method

A headlamp aiming tool includes a linear member and four legs. The first and second legs are used to measure the distance between the headlamps of a vehicle and the height of the headlamps relative to the ground or floor. The tool may also be mounted on the vehicle via the first and second legs and a fastener connected with the third leg arranged between first and second legs. A laser device is connected with the fourth leg and aligned with a centerline of the vehicle to direct a laser beam against a screen in front of the vehicle to indicate the vehicle centerline on the screen. The headlamp light and spacing measurements are used to provide headlamp center points on the screen and to determine the horizontal and vertical offset of the low beam light which is used to adjust the aim of the headlamps.
