Dear Mr. Waldherr: In your letter of February 2 you refer to paragraph S4.5.1 of Moto Vehicle Safety Standard No. 108 and its reference to SAE Recommended Practice J564a, *Headlamp Beam Switching*, April 1964. You ask 'whether there is anything in your Docket related to Rule No. 108 to bring it up to either J564b or J564c.'; Perhaps you misread S4.5.1, but it does allow conformance with J564b a an alternative to J564a. No proposal has been issued requiring or allowing conformance with J564c.; Yours truly, Richard B. Dyson, Assistant Chief Counsel
