The hazard

Issue: On certain trucks, the tail lamps do not turn on when the daytime running lamps (DRLs) are on. New Canadian regulations require that, if a vehicle has dash backlighting, the low beam headlamps and tail lamps must automatically switch on when it is dark or the tail lamps must stay on at all times. Safety Risk: Driving without tail lamps in low light conditions could make the truck less visible and increase the risk of a crash. Corrective Actions: Mack will notify owners by mail and instruct you to take your truck to a dealer to update the vehicle software.
