Zusammenfassung:	Wheel alignment apparatus using a modulated beam of light or radiant energy to determine the attitude of an operational axis of a vehicle with respect to a reflective reference means. A pair of light responsive sensors are disposed on a device that may be attached to a wheel on a vehicle. The energy reflected to each may then be a measure of the attitude of the wheel or its axis with respect to a reference such as the reflector. Means are provided to indicate when each of the sensors is receiving sufficient light energy to prevent false indication of a predetermined alignment relationship. Means are also provided to modify the sensitivity of the sensors in accordance with the relative distance from a reflective reference.
