Replaceable Light Source Information

This notice responds to petitions for reconsideration of the final rule, published on January 12, 1993, that requires the manufacturers of replaceable light sources for headlamps to file dimensional and other information with NHTSA in a public docket pursuant to 49 CFR part 564, Replaceable Light Source Information. Part 564, which currently allows light source manufacturers to file information in the part 564 Docket, is amended to allow vehicle and headlamp manufacturers also to file information in the docket. This notice also amends part 564 to allow changes to be made in light source information previously submitted. Under the amendment, NHTSA will accept a submission for change if the submitter includes a statement that substitution of a modified bulb to replace an unmodified one will not create a noncompliance of that headlamp with Standard No. 108, and submits reasons in support of the statement. In order to evaluate the reasons, NHTSA may publish a Federal Register notice seeking comment. The acceptance of a modified light source will have no effect upon the permissibility to continue the manufacture and use of the original light source.
