I have owned my 2014 GMC Sierra for ten months now. Drove my truck in complete darkness for first time and was shocked at how poor the high beam lights were and the low beams with the fog lights on were not much better. When I got back to town I parked the truck beside a 2007 Chevy and a 2007 GMC truck with OEM lights and was shocked at how poor the lights were on my 2014 Sierra. You have to stay very alert when driving this truck on rural roads.

Also noticed that when it started to snow lightly that the high beams would be pointed toward the trees. This is a accident waiting to happen. When this happened I thought that the lenses might be dirty with road salt, but they were clean. You have to be careful not to out run the lights.

The stock headlights on these trucks are terrible. The fog lights are actually brighter than the headlights and it is dangerous to drive at night on roads that do not have streetlights. According to the salesman at the dealership there has never been any complaints with the lighting on the new trucks. I am hoping that an aftermarket HID kit will make a difference and will send before and after photos to the dealership. It is the only complaint I have with the truck and at the price they charge for these trucks you should be able to see while driving at night.

Hopefully GM will realize how dangerous the headlights actually are and will fix the issue moving forward, maybe even cover the cost of retrofitting with ones that will allow for safe driving in all conditions.

Update from Feb 19, 2015: I purchased an aftermarket HID kit off of Amazon along with a wiring harness. It took about an hour to install everything and low and behold I can actually see where my truck is going in the dark. It cost about $175 after shipping and exchange and the hour of my time to fix the issue. It could be a scary looking project for some but when you are really frustrated by the shortfalls of the vehicle it is worth taking the time to do. Before I installed the HID kit putting candles where the headlight bulbs were would likely have made for brighter headlights.

Update from Mar 15, 2015: The HID kit from Amazon was a Kensun high performance HID with AC canbus conversion and built in warning canceler and anti-flicker, also needed the hid conversion harness with the relay and capacitor. I used 9006 bulbs and they worked just fine. The whole process took about an hour but would leave it to a professional if you are not mechanically inclined.

IN JUNE,2014, I BOUGHT A 2014 GMC 1500 SLE WITH LED PROJECTOR HEADLIGHTS (SINGLE BULB FOR HIGH/LOW). THE LIGHT THEY PUT ON THE ROAD IS SO DIM, IT'S DANGEROUS TO DRIVE IN ANY WEATHER ON UNFAMILIAR ROADS. LESS THAN 40 FEET IN FRONT OF TRUCK, THEY LEAVE A STRAIGHT LINE ACROSS THE ROAD, BEYOND WHICH YOU C-A-N N-O-T S-E-E WHERE YOU ARE GOING. ON WET PAVEMENT, YOU CAN'T SEE AT ALL.

MY TRUCK DID NOT COME WITH FOG-LIGHTS, AND THERE IS NO KIT AVAILABLE ( GM OR AFTERMARKET ) THAT CAN BE PUT ON WITHOUT DAMAGING THE ELECTRICAL SYSTEM ON THE TRUCK!!! THAT INFORMATION IS FROM DEALER SERVICE AND PARTS DEPT. WITH HIGH BEAMS ON, YOU CAN SEE SIGNS REFLECTED A LONG WAY DOWN ROAD, BUT THEY DO NOT PUT MUCH LIGHT ON THE ROAD. I HAVE BEEN TO THE SERVICE CENTER AND HAD THEM ADJUSTED, BUT DID NO GOOD, AS ONLY ADJUSTMENT IS UP / DOWN.

I HAVE ASKED SERVICE DEPT SEVERAL TIMES ABOUT THE LIGHTS BUT THEY DON'T HAVE ANY IDEAS. I HATE TO MAKE A STINK, BUT THE NEXT TIME I CAN GET IT IN I'M GOING TO HAVE TO TAKE A FIRMER STANCE. IF THERE ARE AVAILABLE / OPTIONAL BULBS THAT CAN BE PUT IN, PLEASE LET ME KNOW. THANK YOU, JIM D....LOCUST GROVE, GA

Bought this $47,000 truck and it has the worst headlamp output of any vehicle I have ever owned. Bought it thinking it had basically the same headlamp as the 2011 Buick Enclave I traded in on it since they were both projection lights.

It's very dangerous to drive at night.. My wife will not take it out unless absolutely necessary which is ridiculous. Living in Northern Maine, it gets dark around 3 p,m. during the winter months. I almost hit a moose a few weeks ago due to not being able to see down the road in high beam.. Then I almost hit a pedestrian trying to cross the road in town while on low beam.

I called GM and they claim they have no calls about this issue and I was the FIRST to call in about such a thing, yet all you see online are complaint after complaint. GM is really trying to avoid this 'error' in design.. Zachary, a senior service adviser directly at GM offered me 200.00$ to basically shut the case.. SERIOUSLY? All I want are headlights that are worthy to be on a vehicle that is 47,000$.

Completely disgusted with how GM is handling this situation

I am 63 and at first wondered if my night time vision was getting that bad. Good to hear that all of you have the same percpetion of these lousy head lights. I checked with NHTSA and they have 40 complaints on file as of today - 1-3-14. Be sure to add your voice to the choir at safecar.gov. I have also pitched a complaint to my GMC dealer on their official customer feedback surveys - I was not impressed when I took the vehicle in for a headlight adjustment and got it back much worse than before. The only explanation was - "they adjust them at the factory - we don't have any kind of standard as to how to adjust them." Not a word about this lousy headlight problem that they must by now KNOW about. When I completed my paperwork for the purchase, GMC has a form that I was required to sign in order to get a $900 discount. The form asked me to agree to binding arbitration in return for the discount, and sign away my right to sue. I refused to sign it. Now I am glad I did. This could be a big consumer law suit if GMC doesn't make it right.

This truck is a pain in the butt to drive at night, the headlights are terrible. Have asked the dealership if they can fix the problem, they say there is nothing they can do about that as it is not a problem GM will recognize.

Update from Nov 7, 2015: Still a problem at 15000 miles asked GM about it and was told nothing to fix

Update from Nov 13, 2016: Ask dealer about this before Warranty expired was told that GM has no solution these lights are terrible at night especially in the rain..

Very poor headlights. Can not see each side of the road. If there animals in the ditch or roadside chances are you wont see them. Very dim lights. You can't see much of a difference from low to high beam. Only can see road signs far away that's it. Opposite traffic don't even flash when you forget to dim them. I have had many vehicles and to me they are the worst. My old 2005 GMC had 10 times better lights.

I wrote to GM lets see if it helps. Another complaint was the gas tank protector is wide open on the drivers side wheel well and will pick up lots of sand and debris from the roads including road salt. After a while this will puncture the tank I am sure. Next is the engine's dip stick is way to low and far back by fire wall. You have to be 6 feet tall and stand on a milk crate to get to it. Other then that, I love the truck lots of power great fuel millage and very comfortable. Have had the truck since September 2014. Hopefully GM will rectify this.

Headlights are so dim, in my opinion, to the point of being considered a road hazard. Restricting the ability of drivers to avoid hitting anything that strays into the vehicle's path. I was relieved to see other complaints on this so now I know it's not my imagination. Isn't there a standard or benchmark these headlights must meet to be sold to the public? Any organization out there monitoring this stuff? I just hope and pray no pedestrians and pets wonder in front of me at night. It'll be too late by the time these headlight illuminate the situation.

I would have never bought this truck if I had any Idea how bad the lights are. I have installed after market HID lights big improvement GM should cover the cost. I bought Brightsource lights and I would recommend you don't buy them from Brightsource. The first kit they sent me had a faulty harness he second kit had a faulty ballast.

Their 800 help line implied it was my fault. When they sent the second kit, they sent a insulting note telling me to keep the positive to positive and negative to negative. What an insult!

I ADVISE ANYONE CONSIDERING BUYING THIS VEHICLE TO DRIVE THE VEHICLE AFTER DARK AND NOT ON WELL LIT ROADS TO GET A TRUE EXPERIENCE WITH THE LIGHT, DRIVE ON A DARK HILLY ROAD. MY PREVIOUS VEHICLE WAS A 2010 CHEVROLET SILVERADO 1500 LT. OTHER THAN CHANGING THE BULBS ON THE RIGHT SIDE OF VEHICLE THE LIGHTS WERE GOOD. THE HEADLIGHTS ON THIS PICKUP REMIND ME OF THE FIRST PICKUP MY FATHER OWNED, A 1937 CHEVROLET PICKUP.

I HAVE NOT OWNED ANYTHING BUT A GENERAL MOTORS VEHICLE, UNLESS GM CORRECTS THE HEADLIGHT PROBLEM WITH THIS PICKUP I WILL BE LOOKING AT ANOTHER BRAND. AS OTHERS HAVE SAID, THIS VEHICLE IS DANGEROUS TO DRIVE AT NIGHT. I MENTIONED ABOVE ABOUT CHANGING BULBS IN THE RIGHT SIDE OF THE CHEVROLET PICKUP, THE HAND BOOK WITH THIS GMC PICKUP SAYS TO SEE YOUR DEALER FOR PASSENGER SIDE (RIGHT SIDE) FOR REPLACEMENT. IN OTHER WORDS SPEND BIG BUCKS TO CHANGE THE PASSENGER SIDE BULBS.

Beautiful truck. Quiet, comfortable, good fuel economy. Very difficult to drive at night. Poor visibility at night especially if it is raining or you are driving on new black pavement. Very difficult to see the ditchline to watch for wild animals such as deer. My wife will drive the truck after dark. My 2009 GMC sierra has awesome lights so it is not as if they do not know how to make them right. Went backwards. Everyone should complain on this board so GM may address. Given GM's track record on these issues they will probably default to the ignition switch rope-a- dope denial methodology until someone dies. Luck for me this is a lease so it is time to stop the payments.

This truck has the worst headlights I have ever seen on a vehicle. They cut out so close to the front of the vehicle you have to crawl along to not outdrive them. There is no light to the sides on corners and if you are driving into a dip you can't see anything on the upslope. I think these lights are a definite safety problem and I will never buy another GMC vehicle if GM does not provide a fix for this truck. (Not on the next version, but on this one). If I had driven this truck at night before buying it I would have not purchased it.

I think GM had better address this immediately or it will lead to many accidents and injuries and could be as bad as their problem with ignition switches.

Update from Nov 7, 2015: After being called by the dealer saying that GM had come up with a fix I brought the truck in for repairs. The result was not satisfying in the least. There seemed to be a slight improvement in the high beams but the low beams were worse if anything. They cut off so close to the vehicle that you can not drive at anywhere near a normal speed at night without being afraid you may hit something before you can see it. My wife said she wishes I would trade the vehicle for a Dodge or Ford because she is afraid I will get in an accident.
