Dear Mr. Iwase: This is in response to your letter of November 20, l99 with respect to 'interpretation and/or petition' concerning combination headlighting systems. Koito has asked about the permissibility of two or four lamp headlighting systems in which the upper beam would be provided by integral beam headlamps, and the lower beam by replaceable bulb headlamps. The systems you describe would not be permissible under Standard No. 108, which allows only the three types of headlighting systems that you mention. Integral beam headlighting systems must be comprised of integral beam headlamps which, by definition, are headlamps other than sealed beam or replaceable bulb headlamps. Replaceable bulb headlighting systems are those that incorporate the standardized replaceable light sources listed in Standard No. 108. We are transmitting your request to the Office of Rulemaking, for consideration as a petition for rulemaking. Sincerely, Paul Jackson Rice Chief Counsel;
