What’s wrong with it?
If the low beam headlights go out, the driver may lose visibility, increasing the risk of a crash.
Mack is recalling certain model year 2007-2010 CHU and CXU vehicles, manufactured from October 13, 2006, through December 23, 2009 and equipped with daytime running lights and fog lights.
A short in the fog light circuit may cause the low beam headlight circuit to cut out.
