I had the truck in for service before we left Spokane for Arizona and complained to the service manager. He said I was not the only one who's been complaining. SO FIX THE DAMN HEADLIGHTS! I live 1 mile south of the Canadian border, we average 1 deer kill a year from a vehicle. Now we can't SEE CRAP because of poor headlight performance from a $60,000 truck. Winter is here, longer nite time driving and rain, snow, NEED I go on???? STEP UP GM or after 25 years of buying GM, I'm going RAM!!! FIX THE DAMN HEADLIGHTS>

just as other complaint, the headlights are horrible and dangerous. there is a wall of black when dimmers are on. it's like driving though a very low tunnel and never coming out of it. in contact now with my dealer as the truck is brand new. there is a definite light of black up ahead and must drive very slow. there is fade out. going down a hill is super dangerous!! i turned up the dimmers a small amount but its still very bad. i d'ont need a black wall in front of me. i have owned many trucks and know what lighting is and what is safe.

Update from Oct 9, 2016: update: i changed the low beam bulb myself and adjusted the angle up a little more. i checked to make sure oncoming vehicles were not blinded. i switched the bulb to a sylvania silverstar ultra. this gave me much better vision. and also reduced the black wall up ahead with a fade out. my truck was equipped with a h11 55 watt from factory.
