Hazard description
Certain 4900EX vehicles fail to comply with the requirements of CMVSS 108 - Lighting System and Retroreflective Devices. Additional marker lamps between the required identification lamps and clearance lamps on top of the cab may have been installed during vehicle assembly. These additional lamps, located on the same horizontal line near the identification lamps, may make it difficult for other drivers to distinguish large vehicles under some conditions. Correction: Dealers will remove the additional lamps.
