Although an optical beamsetter is the most accurate way to aim lamps, these are not very common in North America. Foglamps, driving lamps, and visually-aimable headlamps do not require a mechanical aimer or other machine in order to achieve correct visual aim. All ECE (E-code) headlamps are visually aimable, and many newer US (DOT) headlamps can be accurately aimed visually. First, you must determine if your headlamps can accurately be aimed visually. If you have ECE (E-code, European-spec) headlamps, you can aim them visually.
