   (6)  Each vehicle equipped with a turn signal operating unit shall also have an illuminated pilot indicator. Failure of one or more turn signal lamps to operate shall be indicated in accordance with SAE Standard J588e, ‘‘Turn Signal Lamps,’’ September 1970, except when a variable-load turn signal flasher is used on a truck, bus or multipurpose passenger vehicle 80 or more inches in overall width, on a truck that is capable of accommodating a slide-in camper, or on any vehicle equipped to tow trailers.

   (7)  On all passenger cars, motorcycles, and multipurpose passenger vehicles, trucks, and buses of less than 80 inches overall width:

     (i)   When the parking lamps are activated, the tail lamps, license plate lamps and side marker lamps shall also be activated.

     (ii)   When the headlamps are activated in a steady-burning state, the tail lamps, parking lamps, license plate lamps and side marker lamps shall also be activated.

 NOTE: (1) The term ‘‘overall width’’ refers to the nominal design dimension of the widest part of the vehicle, exclusive of signal lamps, marker lamps, outside rearview mirrors, flexible fender extensions, and mud flaps, determine with doors and windows closed, and the wheels in the straight-ahead position.
 This supersedes the interpretation of the term ‘‘overall width’’ appearing in the FEDERAL REGISTER of March 1, 1967 (32 Fed. Reg. 3390).
 (2) Paragraph S3.1 and Tables I and III of §  571.108 as amended (32 Fed. Reg. 18033, Dec. 16, 1967), specify that certain lamp assemblies shall conform to applicable SAE Standards. Each of these basically referenced standards subreferences both SAE Standard J575 (tests for motor vehicle lighting devices and components) which in turn references SAE Standard J573 on bulbs, and SAE Standard J567 on bulb sockets.
 2 See S4.1.1.18.
 (3) Paragraph C of SAE Standard J575 states in part: ‘‘Where special bulbs are specified, they should be submitted with the devices and the same or similar bulbs used in the tests and operated at their rated mean spherical candlepower.’’ The Administrator has determined that this provision of SAE Standard J575 permits the use of special bulbs, including tubular-type bulbs, which do not conform to the detailed requirements of Table I of SAE Standard J573. It follows that the sockets for special bulbs need not conform to the detailed requirements of SAE Standard J567. These provisions for special bulbs in no way except the lamp assemblies from meeting all performance requirements specified in Federal Standard No. 108, including those specified in the basically referenced SAE Standards, and in the subreferenced SAE Standard J575.
