The National Highway Traffic Safety Administration (NHTSA) has restored the blue and green color boundaries within the federal lighting standard. The boundary language was inadvertently removed from Federal Motor Vehicle Safety Standard (FMVSS) No. 108 several years ago when the agency reorganized the standard. Although the NHTSA does not allow taillamps, 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.
