INOPERABLE TAIL LIGHTS

What NHTSA is examining

Odi opened this investigation based on a technical service bulletin and ewr data. Ewr warranty data is aggregate data and individual reports are not submitted.volvo reviewed their warranty data and determined that only 63 of the ewr warranty claims related to the subject vehicles displayed symptoms consistent with the tsb.volvo also noted in their ir response that the tail light configuration is used almost exclusively on tractors that are normally attached to semi trailers.therefore, the tractor lights are normally not the rear most lights on the vehicle.in a normal application, even if one tail light on the tractor was out, the tail light on the trailer would continue to illuminate and provide other drivers of the intentions of the semi trailer driver.pursuant to 49 cfr 396.11 & 13, a commercial vehicle operator is required to perform a pre-trip and post-trip inspection, which includes checking the functionality of the tail lights.given the above information, odi has not identified a safety-related defect trend at this time and further use of agency resources does not appear to be warranted.the closing of this investigation does not constitute a finding by nhtsa that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.
