§ 46.37.320. Authority of state patrol regarding lighting devices or other safety equipment.
(1) The chief of the state patrol is hereby authorized to adopt and enforce rules establishing standards and specifications governing the performance of lighting devices and their installation, adjustment, and aiming, when in use on motor vehicles, and other safety equipment, components, or assemblies of a type for which regulation is required in this chapter or in rules adopted by the state patrol. Such rules shall correlate with and, so far as practicable, conform to federal motor vehicle safety standards adopted pursuant to the national traffic and motor vehicle safety act of 1966 (15 U.S.C. Sec. 1381 et seq.) covering the same aspect of performance, or in the absence of such federal standards, to the then current standards and specifications of the society of automotive engineers applicable to such equipment: PROVIDED, That the sale, installation, and use of any headlamp meeting the standards of either the society of automotive engineers or the United Nations agreement concerning motor vehicle equipment and parts done at Geneva on March 20, 1958, or as amended and adopted by the Canadian standards association (CSA standard D106.2), as amended, shall be lawful in this state.
(2) Every manufacturer who sells or offers for sale lighting devices or other safety equipment subject to requirements established by the state patrol shall, if the lighting device or safety equipment is not in conformance with applicable federal motor vehicle safety standards, provide for submission of such lighting device or safety equipment to any recognized organization or agency such as, but not limited to, the American national standards institute, the society of automotive engineers, or the American association of motor vehicle administrators, as the agent of the state patrol. Issuance of a certificate of compliance for any lighting device or item of safety equipment by that agent is deemed to comply with the standards set forth by the state patrol. Such certificate shall be issued by the agent of the state before sale of the product within the state.
(3) The state patrol may at any time request from the manufacturer a copy of the test data showing proof of compliance of any device with the requirements established by the state patrol and additional evidence that due care was exercised in maintaining compliance during production. If the manufacturer fails to provide such proof of compliance within sixty days of notice from the state patrol, the state patrol may prohibit the sale of the device in this state until acceptable proof of compliance is received by the state patrol.
(4) The state patrol or its agent may purchase any lighting device or other safety equipment, component, or assembly subject to this chapter or rules adopted by the state patrol under this chapter, for purposes of testing or retesting the equipment as to its compliance with applicable standards or specifications.
