TITLE: AIMABILITY OF HEADLAMPS

ATTACHMT: ATTACHED TO LETTER DATED 3-4-93 FROM JOHN WOMACK TO GUY DORLEANS (A40; STD. 108)

TEXT: Valeo Lighting is currently studying new principles for aiming small circular headlamps. Two versions are considered:

Version A:

A pair of headlamp spacer rims, hereunder designated by the acronym "HSR", are permanently attached to the car. The lens of each headlamp has 3 bosses, so that the HSR shown on sheet A1 easily finds its place between the lens and a standard circular adpater for 5" 3/4 sealed-beam units. Sheet B2 shows the assembly, before adjunction of readily available aimers for 5" 3/4 sealed beams units.

The pair of "HSR" is placed in an accessory kit, in the trunck. Relevant instructions for use are included in the owner's manual.

Version B:

The part shown on sheet B1 replaces the functions of the HSR and the function of the standard circular adapter.

The B1 specific adapter (see sheet B2) is the link between the lens of the headlamp and the external 5" 3/4 aimers, these latter devices being available in the United States for more than 30 years.

In this case also, a pair of specific adapters are sold with the car, and permanently placed in the trunck of each car. Relevant informations are provided by the owner's manual.

-------

Valeo respectfully asks NHTSA to confirm that both versions are in compliance with Standard 108.

Do not hesitate to contact me if further clarifications are needed.
