Resumen del asunto	Con las nuevas luces LED, ¿cuántas de las pequeñas luces de freno, traseras o intermitentes deben fundirse antes de que la luz se considere defectuosa/infracción y/o fuera de servicio?
Justificación o necesidad	Con los modelos más recientes de vehículos comerciales, cada vez se instalan más luces LED. Estas luces están empezando a fallar y los agentes necesitan saber cuántas de las pequeñas bombillas internas deben fundirse para que el vehículo se considere defectuoso y cuántas deben estar fuera de servicio para que se considere fuera de servicio.
Solicitud de acción	Se debería añadir a los criterios OOS un porcentaje de bombillas pequeñas (50%) que deben fundirse para cumplir con dichos criterios. Algunas jurisdicciones exigen que las luces sean visibles a 150 metros. Quizás convendría realizar pruebas para determinar dicho porcentaje. En la actualidad, los Out-of-Service Criteria no contemplan una situación de iluminación parcial. Fallo de la lámpara LED Las preguntas de inspección relacionadas con fallas en lámparas LED incluyen: ¿Cuándo se debe reemplazar una lámpara LED defectuosa? ¿Cuántos LED individuales deben permanecer encendidos para que la lámpara sea aceptable? ¿Existe alguna "regla" de fallo para cada tipo y marca de lámpara LED?
Medidas adoptadas por el comité	This matter had already been addressed with Issue Request 00-014-VEH from 2000. A letter was written to NHTSA after meeting in Tampa. Information was reviewed and the following was reported. Upon receipt of this Issue Request, the Vehicle Committee heard a presentation on this issue in October 2004. Until such time as an industry standard can be established, recommended guidance to inspectors is that if any diodes are functioning, the light should be considered not a violation and only when all diodes are not working, would the light be in violation and possibly out of service (ie: rear turn signal). On October 4, 2004, CVSA sent a letter to NHTSA and FMCSA requesting information/guidance related to this issue. The letter indicates a previous letter had been sent asking for the information/guidance. NHTSA did not offer any meaningful guidance for enforcement personnel. It was stated that one LED manufacturer provides cards to customers to measure light intensity. A member suggested sending a letter to LED lighting manufacturers to establish the lowest acceptable rating. Another suggested that the committee should continue to pursue a satisfactory answer from NHTSA and FMCSA as well. FMCSA stated that NHTSA has not yet drafted anything about enforcement of this issue. The Vehicle Committee requested another letter be sent to NHTSA and FMCSA. It was then decided to close the LED issue until the Vehicle Committee receives additional information to allow the Committee to make a determination. The following information was later received in regards to LED lights from the Province of Alberta: Canada's National Safety Code Standard 11, Part B, addresses individual LED's of any one lamp assembly as below. NSC STANDARD 11, PART B Periodic Commercial Motor Vehicle Inspections (PMVI) CCMTA TRUCK AND TRUCK-TRACTOR VEHICLE SAFETY INSPECTION PROGRAM INSPECTION METHODS AND STANDARDS REJECT IF: Any lamp fails to illuminate, is missing, broken, cracked, insecurely mounted, has moisture visible in the interior, is fitted with a cover, does not meet CMVSS, DOT or SAE standards and be so labeled, 25% or more of LED's of any one lamp assembly are non functional, or does not meet requirements as set out below. The Vehicle Committee again discussed this issue in light of the Canadas National Safety Code Standard. A NHTSA study indicated 80% of the population cannot tell when lights have lost 25% of their intensity. FMCSA and NHTSA could not provide an enforcement standard so the Vehicle Committee agreed to leave the Out of Service Criteria as is.

This matter had already been addressed with Issue Request 00-014-VEH from 2000. A letter was written to NHTSA after meeting in Tampa. Information was reviewed and the following was reported.

Upon receipt of this Issue Request, the Vehicle Committee heard a presentation on this issue in October 2004. Until such time as an industry standard can be established, recommended guidance to inspectors is that if any diodes are functioning, the light should be considered not a violation and only when all diodes are not working, would the light be in violation and possibly out of service (ie: rear turn signal).

On October 4, 2004, CVSA sent a letter to NHTSA and FMCSA requesting information/guidance related to this issue. The letter indicates a previous letter had been sent asking for the information/guidance. NHTSA did not offer any meaningful guidance for enforcement personnel. It was stated that one LED manufacturer provides cards to customers to measure light intensity. A member suggested sending a letter to LED lighting manufacturers to establish the lowest acceptable rating. Another suggested that the committee should continue to pursue a satisfactory answer from NHTSA and FMCSA as well. FMCSA stated that NHTSA has not yet drafted anything about enforcement of this issue. The Vehicle Committee requested another letter be sent to NHTSA and FMCSA.

It was then decided to close the LED issue until the Vehicle Committee receives additional information to allow the Committee to make a determination.

The following information was later received in regards to LED lights from the Province of Alberta:

Canada's National Safety Code Standard 11, Part B, addresses individual LED's of any one lamp assembly as below.

NSC STANDARD 11, PART B Periodic Commercial Motor Vehicle Inspections (PMVI) CCMTA TRUCK AND TRUCK-TRACTOR VEHICLE SAFETY INSPECTION PROGRAM INSPECTION METHODS AND STANDARDS REJECT IF: Any lamp fails to illuminate, is missing, broken, cracked, insecurely mounted, has moisture visible in the interior, is fitted with a cover, does not meet CMVSS, DOT or SAE standards and be so labeled, 25% or more of LED's of any one lamp assembly are non functional, or does not meet requirements as set out below.
