TITLE: NONE

ATTACHMT: LETTER DATED 10/29/84 FROM FRED W. BOWDITCH -- MVMA TO DIANE K. STEED -- NHTSA, PETITION

TEXT: Dear Mr. Bowditch:

On October 29, 1984, the Motor Vehicle Manufacturers Association filed a petition for rulemaking to amend Motor Vehicle Safety Standard No. 108, Lamps, Reflective Devices, and Associated Equipment.

The petition requested "removal from section 4.1.1.36(a) (2) of the limitation requiring the three aiming pads to be located on the exterior face of the headlamp lens." You have suggested the mounting flange at the lens-reflector joint as an acceptable alternative location for the aiming pads. The language suggested in the petition for amendment of S4.1.1.36(a) (2) would also allow all three legs to be adjustable on the headlamp aimers.

The agency has proposed amendments to Standard No. 108 (49 FR 47880) to delete the final sentence of paragraph S4.1.1.36(a) (2) with reference to aiming locating plates, and to delete Figures 9-1 and 9-2. Thus, this aspect of your petition has already been granted. We have filed your petition as a comment in the docket to be considered in future rulemaking action on this subject. Further, we interpret the words "The exterior face of each...lens" in paragraph S4.1.1.36(a) (2) to mean all portions of the lens face including the mounting flange which is a molded and indivisible part of the lens. Thus, no rulemaking is considered necessary to implement this item of your petition. Your request also included a suggestion that the minimum height of the lettering for the adjustment of the legs on the aimer adapter should be reduced from 0.25 inch to 4 mm. This is being addressed in pending rulemaking. Therefore, no further action is necessary at this time.

Sincerely,
