These are quite possibly the worst headlights on a GMC truck to ever roll off of the assembly line.  The headlights on the the 2014 GMC Sierra pose a great danger to anyone attempting to drive at night due to poor light dispersion and overall build quality of the headlight assembly.  The need to modify lighting on a vehicle well over $40,000 should not need to be made.  General Motors needs to address this issue befor serious harm or death occurs.
