Adjusting the headlights of most Chevrolet pickups is almost universal. But many drivers still ask us to clarify the processes they should follow to adjust the headlights of their specific Chevrolet truck.

We will try to be more specific about the 2004 Chevy Silverado, but headlight adjustment procedures should work with all Chevrolet pickups from 1999 to 2006 models as well.

How to adjust the headlights on 2004 Chevy Silverado

Before creating this guideline, we have done some research regarding the process people are sharing on the internet. What we have noticed is that most of the information is valid but not that elaborative. Therefore, we will try to break down each of the sections in a broad manner so that you can complete the job without any complications.

Before going into the long discussion, here are the procedures you can follow to adjust the headlights of your 2004 Chevy Silverado-

The first step, which is true for aligning most GM and Chevy vehicles, is making the perfect placement. You can only think about doing the adjustment when the LED headlights of the 2004 Chevy Silverado are not aligned. How come you know whether it is aligned or not?

Well, that is why making the perfect placement is more than necessary. While most of the drivers suggest keeping the pickup 20 feet away from the wall, we believe keeping it 12 to 20 feet away will suffice.

Once you have placed the 2004 Chevy Silverado in the right place, its time to move into the next section-

Turn on the headlights and throw the headlight beams on the wall.

In this particular step, you have to do the measurement. To do the measurement, open the hood and turn the headlights on. If the lights are on, you should see two headlight beams on the wall. If you find any misbalance between the driver side low beam and the passenger side low beam, you will have to go for the alignment. Do not get fret at all.  It is not the kind of job that is overwhelming. Anybody with slight experience should be able to do the job with complete dexterity.

The only thing you will need is confidence and a little bit of perfect guideline, which is why we are here right now.

If you notice that the driving side low beam and the passenger side low beam are not well aligned, you can move into the third step, which is finding out the alignment screws.

Locate the head screws

The function of the two head screws that you will notice on the Chevy 2004 Silverado is to move the light left and right or upside down. Depending on the light displacement, you have to use these screws to make them realigned. Here are some of the simple steps to follow-

  • The inside screw will move the lights left and right, whereas the inside screw will move the beams up and down.
  • Turning the outside screw counterclockwise will bring your headlights down. Turning the screw clockwise will raise the light up.
  • By turning the inside screw counter or clockwise will allow you to move the light beam left and right as well.

Make the adjustment

Now that you know how one should be moving the beam left and right or up and down, it is time to get into the real work, which is doing the adjustment. Here are some of the tips you may follow to make the adjustment-

  • Many people prefer going with a measuring tape to measure the amount of adjustment they need to make. If that seems to give you trouble, you can also use your eye for the measurement. At the end of the day, it is the comfort of your eye that should get the high-end priority.
  • Fix the amount of adjustment you will need to make by calculating through your lenses. Once you are comfortable with your decision, get into the work.
  • Don’t be in rush. Take your time and do the adjustment so that you do not have to face any complications in the longer run.
  • Once you are comfortable with the alignment, close the hood and go for the next ride.
