TITLE: Request for Interpretation

ATTACHMT: Attached to letter dated 8/3/92 from Paul J. Rice to Tilghman (Tilman) Spingler (A39; Std. 108)

TEXT:

FMVSS 108 requires for Replaceable Bulb Headlamps a vertical aim range of > +/- 4 degrees and a horizontal aim range of > +/- 2.3 degrees. Does this mean that a headlamp has to meet both ranges in addition, i.e. 2.5 degrees horizontal at a full range of 4 degrees vertical and vice-versa? Would it be possible to give me a "quick" answer by fax?
