ATTACHMT: ATTACHED TO LETTER DATED 1-22-93 FROM GUY DORLEANS TO CHIEF COUNCEL, NHTSA

TEXT: We have received your letter of January 22, 1993, asking for an interpretation of Motor Vehicle Safety Standard No. 108 as it relates to aimability of headlamps.

Valeo is currently studying new principles for aiming small circular headlamps. It appears that these headlamps will require unique aiming adaptors (meaning that the Hopkins universal adaptor cannot be used with them). These adaptors will be placed in the trunk of any vehicle with which they are supplied, and relevant instructions for use will be included in the vehicle operator's manual. Valeo has asked for confirmation that each version complies with Standard No. 108.

Standard No. 108 does not require that an aiming adaptor be provided with a motor vehicle, only that the vehicle's headlamps be capable of mechanical aim. Therefore there is no legal requirement that an adaptor be provided. However, without such an adaptor, an owner of a vehicle with the new headlamps may encounter difficulties at State inspection stations where the Hopkins adaptor is in use, and at repair facilities when headlamps are replaced or after body work has been performed that necessitates reaim of headlamps. Therefore we believe that provision of the adaptor and aiming information would enhance consumer acceptance of the new headlamps.
