Headlamps shall be mounted as specified in FMVSS 108 and as follows:
(a) Spacing. Headlamp units installed after November 15, 1975, shall not be closer to the centerline of the vehicle than 30 cm (12 in.) measured from the center of the lens, except on motorcycles and motorized bicycles.(b) Covers. No grille, transparent lens cover, or any other obstruction shall be in front of the headlamp lens on vehicles manufactured and first registered in California after January 1, 1968, except for headlamp concealment devices meeting FMVSS 112 that automatically move out of the way when the headlamps are turned on. Transparent lens covers are permitted in front of the headlamps of motorcycles originally equipped with such transparent covers, if the covers do not affect compliance of the headlamps with FMVSS 108.(c) Aiming Obstructions. Headlamps on vehicles other than motorcycles shall be mounted so the plane of the aiming pads is not more than 24 cm (9.5 in.) behind the front of the vehicle for 146-mm (5 ¾ -in.) headlamps and not more than 26 cm (10.2 in.) for all other headlamps in the area necessary for horizontal aiming with mechanical aiming machines. This requirement may be complied with by use of movable hood or grille components that can be opened without tools or removal of any part of the vehicle. This subsection does not apply to headlamps on authorized emergency vehicles operated by law enforcement agencies.Cal. Code Regs. Tit. 13, § 692
