The National Highway Traffic Safety Administration (NHTSA) issued a proposed rule to restore the blue and green color boundaries within the federal lighting standard. The boundaries were inadvertently removed from Federal Motor Vehicle Safety Standard (FMVSS) No. 108 several years ago when the agency reorganized the lighting standard. Although the NHTSA does not allow tail lamps, headlamps and or side markers to be blue or green, it is possible to incorporate the color into a lens and still comply with the standard’s white, amber or red-light restrictions. Therefore, the NHTSA is proposing to reinsert references to blue and green color boundaries within paragraphs of S14.4.2.2, which governs the haze testing process.
