本条款规定了美国联邦法规第49篇中关于车辆反光器（Reflex Reflectors）的安装位置、技术规格及替代材料要求。核心内容包括：反光器需按§393.11规定位置安装，若受结构限制无法达到381mm最低高度，应尽可能接近；永久反光器须牢固安装在刚性部件上，临时反光器则固定在货物或拖挂车上。自1968年12月25日后制造的车辆，其反光器必须符合FMVSS No. 108标准；特定类型车辆（如凸出载荷、Driveaway-Towaway作业车等）需符合SAE J594标准。此外，允许使用符合ASTM D 4956-04标准的反光贴膜作为侧面反光器的替代品，但需满足特定性能指标。

(a) Mounting. Reflex reflectors shall be mounted at the locations required by § 393.11. In the case of motor vehicles so constructed that requirement for a 381 mm (15-inch) minimum height above the road surface is not practical, the reflectors shall be mounted as close as practicable to the required mounting height range. All permanent reflex reflectors shall be securely mounted on a rigid part of the vehicle. Temporary reflectors on projecting loads must be securely mounted to the load and are not required to be permanently mounted to a part of the vehicle. Temporary reflex reflectors on vehicles transported in driveaway-towaway operations must be firmly attached.
(b) Specifications. All required reflex reflectors (except reflex reflectors on projecting loads, vehicles transported in a driveaway-towaway operation, converter dollies and pole trailers) on vehicles manufactured on or after December 25, 1968, shall meet the applicable requirements of FMVSS No. 108 in effect on the date of manufacture of the vehicle. Reflex reflectors on projecting loads, vehicles transported in a driveaway-towaway operation, and all reflex reflectors on converter dollies and pole trailers must conform to SAE J594—Reflex Reflectors, December 2003.
(c) Substitute material for side reflex reflectors. Reflective material conforming to ASTM D 4956-04, Standard Specification for Retroreflective Sheeting for Traffic Control, may be used in lieu of reflex reflectors if the material as used on the vehicle, meets the performance standards in either Table I of SAE J594 or Table IA of SAE J594—Reflex Reflectors, December 2003. (See § 393.7(b) for information on the incorporation by reference and availability of these documents.)
(d) Use of additional retroreflective surfaces. Additional retroreflective surfaces may be used in conjunction with, but not in lieu of the reflex reflectors required in subpart B of part 393, and the substitute material for side reflex reflectors allowed by paragraph (c) of this section, provided:

- (1) Designs do not resemble traffic control signs, lights, or devices, except that straight edge striping resembling a barricade pattern may be used.

- (2) Designs do not tend to distort the length and/or width of the motor vehicle.

- (3) Such surfaces shall be at least 3 inches from any required lamp or reflector unless of the same color as such lamp or reflector.

- (4) No red color shall be used on the front of any motor vehicle, except for display of markings or placards required by § 177.823 of this title.

- (5) Retroreflective license plates required by State or local authorities may be used.
