Headlight Illumination Issues

Recommended Posts

Well, since some of you think my head lights are adjusted to high since I get flashed by traffic; I had them adjusted two turns down ward.

 

I hope this works because I'm tired of the a$$holes flashing me all the time. I also hope my visabilty remains awesome like it was on the previous setting.

High beams were good on mine but low were not. All got fixed up when I installed a 2.5" leveling/lift kit.

If you leveled your truck then your headlights are too high. That's why you think it's fixed. Now it's like driving with you highs on. When lights are set from the factory, the truck isn't level (rear is higher). I leveled the back of my truck (hadn't had a chance to re aim the lights then and the same day had a heavy load in the bed and I could see great. Because it was like driving with high beams. When I switched to high beams I could see no difference except the lights were shining in the sky. That's why you're seeing better now. Remember, the low and high beams use the same bulb on the Sierra and the only difference is a shutter that raises and lowers from high to low. I have me lights tweaked with the cutoff line just right where I can still see good and not blind oncoming traffic.

I have a good place to set mine. A level slab on a brick wall using mortar joints as a guideline. The key is to have them adjusted the same. You can tell when driving. You want to see the cutoff line and not have a lot of reflection on signs like when on bright. It might take you a few times to get them perfect.

Everyone has an opinion. Some believe the headlights suck, some think they're fantastic. Those that think they are fantastic haven't driven a vehicle with great lights or they just haven't spent much time with these.

 

That's a pretty bold statement to make. Just because I don't have a problem with the headlights on my Sierra means I don't know "great lights"?

I've had factory HIDs, after market HIDs, after market bulbs and everything in between in a lot of different vehicles, and I drive city streets and back roads country where cell phones don't work. Are they the best I've ever had - no. Are they the worst - far from it.

My neighbor had a 14 Sierra and he said he never gets flashed. I'll probably line our trucks next to each other; in front of my garage. I'll align my cut off line with his.

 

Good thing about these headlights, they're super easy to adjust.

Wow.... did he feel the shake or say anything about it after driving it? What speed does the truck shake @?

Good thing about these headlights, there easy to adjust. The nice cut off line makes it super easy to adjust.

Yes that would work. If u find they are still a bit low you can always raise them a 1/4 turn at a time until you get them tweaked.

Maybe the guys that don't have problems with their lights have better nighttime vision and those you who don't like them, can't see as well at night anyways.

Nothing personal, but I'm of the camp that these lights are poorly designed. I had a 6 volt VW that had worse lights over 40 yrs ago. The GMT 900 had much better lights, IMO . This is a $40-50k truck and it's 2014. The bar is set higher.

Hey folks, all of us who have the aforementioned truck know that the headlights suck! What have you found to be the best solution for the pitiful low beams?

 

Thanks

Just a thought, I do not own one of these to know for sure but what I have noticed is a lot of them seem to be misaligned. I drive a Superduty and as you guys know they are tall, I almost never get lights bothering me in my mirrors or from on coming traffic unless it's the moron that doesn't turn off the brights. Recently since it is dark on my way to work now I have noticed more and more that the K2XX headlights will beam directly into my side mirrors and seem bright. I would think if they are pointed high enough to be bothering me in my side view mirror that they would not be working very good for the driver either. Just a thought and maybe something you guys could check pretty easy

Go to the 'Mods' subforum, lots of info there. Cheapest fastest partial fix, enough to see, is a HID bulb kit.

Funny, A few days ago, I was driving home from a long trip, on a 2 lane secondary road, after dark and I was thinking...boy this truck has great headlights. Different strokes, I guess.

Not different strokes.... different trucks. The OP is complaining about the headlights on a Sierra, which are not the same headlights you have on your Silverado. apples and oranges.

Yup, the Sierra's use a single (crappy) projector for low and high, with just a shutter that raises for high beam. The light output, and beam pattern on low is horrible, I would call dangerous. Then go to high, which it does by raising the shutter, and the beam pattern and light output is equally as bad, with the majority of the beam pattern going 10 degrees up in to the trees. It can not be adjusted down, as you would think, because then the low beam would point to the ground, as the shutter height is not adjustable.

Again, the cheapest, easiest fix is to install HID bulbs into the existing projectors. My 35w-4500K HID bulbs have at least made the truck safe to drive at night, and took about 1-2 hours to install. This gives good/acceptable light output, but the other beam pattern problems are still not fixable. On high with the HID's the 10degree up angle problem is enough to think your going to call in planes to land, not kidding. And if you drive under a forest canopy, as I do alot, it is very distracting, but at least you can see.

Some have installed complete new projectors with great results, however this requires extensive mods.

Best of luck.

      Looking to upgrade my halogen headlight housing (reflector) light output with some LED headlight bulbs.
       
      I understand many people say not to do it as it blinds others, however I rarely drive at night and even then I live in a very rural area with little traffic. Most of the usage with be during the day with the DRL’s. 
       
      So does anyone have recommendations for what kind of LED bulb I should go with, one that works good in the reflector style headlight housing?
       
      Looking for a simple bulb swap, I think you should be able to just swap the bulbs out right?

      Question ?? does anyone know if the 2018 Yukon "HID" headlight assembly will fit my 2015 Yukon ? and if so are they just plug and play or are the wiring harness's different ? I've been running aftermarket HID's and I'm tired of always having to work on them, just not reliable and the stock halogen bulbs in projectors just plain suck !!

      Headlights are standard driving equipment for every vehicle. Headlight plays a very important role in road driving. If there is not enough light, the drivers cannot see the front clearly. Headlight types can be differentiated due to the chips inside. Most vehicles are equipped with halogen bulbs, which will gradually be dim. To deal with this, you can choose the best LED headlights as the replacement.
       
      While search in Wiki, headlight just means the light given by the headlamp, which is the term for the headlight device. And most headlamp can be divided into the headlamp housing, headlight, wiring harness, fog light and turning signal, but fog light and turn signal will be separated with the headlamp assembly in some car models such as Jeep Wrangler.
       
      Headlight Configurations
      As for the headlight, it has three main parts, high beam, low beam and daytime running lights (DRL).
       
      High Beam
      The high beam can be also called as main beam, driving beam or full beam, which provides a bright and centered light on the front. The high beam can only be used while there are no oncoming vehicles in the extremely dark driving road, as the high beam is too bright to blind the oncoming vehicles or pedestrian and make accident happened.
       
      Low Beam
      Low beam, also sometimes termed as the dipped beam, passing beam or meeting beam, can provide an adequate designed light for forward and lateral illumination. The low beam is limited so as to control the glare toward the oncoming vehicles and pedestrian. Thus, the low beam can be used wildly in the night time.
       
      Daytime Running Light (DRL)
      Daytime running light, as the name referred, can be used in daytime driving. As a kind of signal light, the DRL need to be turned on as to show other drivers you are coming towards. According to figures, turning on the DRL while driving on road can reduce accident by 12.4% and reduce the risk of death rate by 26.4%. Some high-end vehicles are equipped with LED driving lights for DRLs nowadays.
       
      Factors Influence the Headlight
      Beam Type
      Most vehicles are equipped with Halogen bulbs as the driving light source for the factory headlights. As we have compared before that, halogen headlight will be dim and the light will be yellow or even amber as the driving time gets by. And the LED driving lights can be the best replacement for the Halogen, as the LED headlights are much brighter but consuming less power. And LED can be working for about 30,000 to 50,000 hours, much longer than the halogen headlights. As the configuration is easy, LED headlights can directly replace the halogen headlights and nothing need to be modified.
       
      Some may claim that their vehicles are equipped with HID headlights. HID headlights are much better than halogen headlights, but there is one disadvantage—it needs 3-5 seconds to warm up the headlight and then the headlights can work normally. While LED headlights do not have such kind of problem. However, if you want to upgrade the HID headlights with LED headlights, some wiring may need to be modified. Thus, the LED headlights may be better comparing with halogen headlights and HID headlights.
       
      Lighting Effect
      In fact, the lighting effect is mainly influenced by the headlight housing. There are mainly two configurations of headlight housing—reflector housing and projector housing.
       
      Reflector Housing
      For vehicles using reflector housing, the light will be reflected as the light is on. Equipped with the reflector housing, the light can be scattered in a wild range with flood beam but there will be some unused light. Many halogen headlights are equipped with reflector housings.
       
      Projector Housing
      As for vehicles with projector housing, light is projected through the lens, which can make a better pencil beam. And also, using the projector lens, the light will not scatter in wildly, which will give more accurate and bright light. Many LED headlights and HID headlights are used projector housing. Thus, for better lighting performance, you can upgrade the reflector headlight housing with projector headlight housing.
       
      Choose the Best LED Headlights
      The headlight assembly for normal vehicles like sedan, SUV, and trucks, maybe a little bit hard to upgrade, which needs huge modifications. However, you can choose to upgrade with the LED headlight bulbs. Normally, every headlight has the bulbs inside, and most factory bulbs are halogen bulbs. Due to the configuration of the LED is similar to halogen bulbs, LED can directly replace the halogen bulbs and do not need further modification. Just plug and play, you can get the new LED headlights.
       
      As we have mentioned above that headlight has the high beam, low beam, and DRL, you need to pay attention to when upgrading the headlights to LEDs.
      1. You need to make sure the plug type of your factory halogen bulb type and then choose the corresponding LED plug types.
      2. Halogen bulbs and LED headlight bulbs are of the same plug type, which has the Hi-lo beam bulbs and single beam bulbs. For hi-lo beam bulbs, one pair of LED headlight bulbs can support both high beam and low beam, while vehicles need single beam for high beam and low beam, you need to purchase 2 pairs to separately support high beam and low beam,
      3. If you have upgraded the reflector headlight housing into projector headlight housing, the plug type changes and you need to check the plug type which can fit your new projector headlight housing.
      4. For some vehicles which designed the high beam together with DRL using the same bulbs, upgrading the bulbs will be a little bit difficult. You need to add extra DRL decoders to avoid bulb working error. Otherwise, your DRL cannot work in a normal way.
       
      Jeep Wrangler Headlights
      Jeep Wrangler can also upgrade the headlights with the LED headlight bulbs. However, there are also many different kinds of Jeep Wrangler headlight assembly which can be easily replaced by Jeep Wrangler. The factory Jeep Wrangler headlights are reflector headlight housing with halogen bulbs which may not look very cool and practical. So how about upgrading the headlight with LED driving lights.
       
      Auxbeam Jeep Wrangler headlights have many different choices for you. All Jeep Wrangler projector headlights include the high beam, low beam and DRL (sometimes will also be called as atmosphere lights), which is convenient to upgrade all the thing at the same time. And the installation steps would not be hard. Just remove the old headlight and unplug them and install the new headlights on then plug them on.
       
      Conclusion
      Also, there are many different kinds of LED driving lights that can be installed on the bumper or bull bar. LED driving lights can be the auxiliary lights as you need more light in driving. Upgrading your headlight into LED projector headlight may be better for both practicability and aesthetics. Choose the best LED headlight solution according to your vehicle types. LED headlights can help you get more brightness.

      2015 Chevrolet Silverado 3500 WT crew cab passenger side complete headlight assembly chrome. The back of the dust covers have been cut open to fit LED lights as well as give more airflow to cool down.  I am transferring the LED lights to my new headlight assembly and will put brand new bulbs in it.
       
      This will NOT fit the 1500. I’m certain It’s for 2014-2018 2500 & 3500 but I believe there’s other applications as well such as Tahoe and Suburban. 
       
      Prices range from $625 to $800 for new OEM! I know, absolutely ridiculous!!!  I have attached a couple of pictures with prices to show both Google and EBay.
       
      $500 includes free shipping!  Last picture below is the actual headlight.
