Abstract
A headlight for a motor vehicle incorporation devices for measuring the amount of deviation of the beam of light produced thereby from the desired axis. The first deviation measuring device, which is used for measuring the amount of deviation of the beam in the horizontal direction, includes a calibrated rod extending between either the reflector and the headlight body, in the case of a movable reflector type headlight, or between the vehicle body and the headlight body, in the case of a movable unit type headlight. The second deviation measuring device, which is used for measuring the amount of deviation in the vertical direction, includes a level secured to the reflector or headlight body.
Claims9
A motor vehicle headlight incorporating a device for measuring an amount of deviation of a beam of said headlight from a predetermined axis, comprising:
- an outer body;
- a front lens covering a front opening of said outer body;
- a reflector positioned within said body;
- means for mounting said reflector to said body so that said reflector is pivotally adjustable in position in horizontal and vertical directions;
- first deviation measuring means for measuring an amount of deviation of said beam from said predetermined axis in said horizontal direction;
- second deviation measuring means for measuring an amount of deviation of said beam from said predetermined axis in said vertical direction, said second deviation measuring means comprising a level secured to said reflector, said level having a graduation means associated therewith for measuring an amount of upward or downward deviation of said beam from said predetermined axis, said second deviation measuring means being located at an upper portion of said reflector;
- and
- a mirror means disposed above said graduation means, said front lens being free of lens steps in a region forward of said mirror means, said mirror means allowing said graduation means to be observed through said region of said front lens free of lens steps from outside of said front lens.
