If you’ve just bought a new car and it has aftermarket headlights, then you might be wondering how to adjust them.
The good news is that adjusting the aftermarket headlight is not that difficult. You can complete the process in only a few minutes.
In this article, you will be learning everything you need to know about how to adjust aftermarket headlights.
10 Steps To Follow: How to Adjust Aftermarket Headlights
Step 1: Parking Light Adjustment.
Before adjusting the headlights, you need to change the parking lights to be at a level that you are comfortable with. So first, turn on the parking light and then turn on your headlight switch.
Now, adjust the angle of the parking light just like you would in an ordinary car for nighttime driving. Once the angle is set, then turn the parking light off.
Step 2: Headlight Adjustment.
Once you have adjusted the parking lights, it is now time to adjust the headlights.
The headlight adjustment will require you to use a wrench and an adjustable wrench or a socket wrench and an adjustable socket set.
You might also need some assistance from another person to be able to loosen and tighten the bolts.
Step 3: Headlight Beam Adjustment.
You can choose from two types of headlight beams: a wide beam and a narrow beam pattern.
Narrow beam patterns are more focused since they have less light scatter, while wide beams are brighter since they cover a wider area.
You need to turn on your headlights and use the adjustable wrench to change the headlight beam pattern, just like you did in the previous step.
Step 4: Headlight Aiming.
If you want to aim your aftermarket headlights properly, then there is a technique that can be used for it called the three-point method.
It is a standard used by car manufacturers when aiming the headlights of their new cars. You need to make use of a tape measure and then put it on the screen or headlight lens holder.
Make sure that the center of your headlights is lined up with the uppermost part of the screen/lens holder using a tape measure.
Step 5: Aiming for the First Time.
If it is your first time to aim your headlights, you will need to follow a particular procedure to achieve the right results.
For instance, if you are currently using one headlight aimed at 15 degrees and the other one has an angle of ten degrees, you need to use a tape measure to find the difference between them.
You should also know that if you are aiming your headlights for legal reasons, they have to be aimed at 30 degrees.
Step 6: Maintaining Your Headlights Properly.
Whether or not you adjust the aftermarket headlights properly, you still need to maintain them to make sure that they will last for as long as possible.
So, you will have to change your car battery regularly and clean the headlights frequently with a cloth or special wipes designed for cleaning headlight lenses.
Step 7: Using an Automated Electrical Adjustment Device.
If you are using a car with an automated electrical adjustment device, you can save yourself the trouble of adjusting your headlight manually.
As long as the headlights are factory installed, they should work fine with aftermarket headlights, so they are worth the shot even if you have aftermarket headlight kits.
Step 8: Headlight Height Measurement.
There are mainly three different ways to measure the height of your headlights, and they include using a regular ruler, taking measurements with both feet on the ground, and then using an aiming rod to measure while in the car.
Whichever way is the most comfortable fit for you is the one you should use.
Step 9: Headlight Height Adjustment.
To adjust your aftermarket headlights, you will have to loosen the nuts on the mounting bolts for them with a wrench or an adjustable wrench.
As soon as they are loose enough, you can use an adjustable socket wrench or a socket set to make the necessary changes. Then, tighten them again afterward, and you are done.
Step 10: Bulb Replacement.
Some of the aftermarket headlight kits come with headlights, and some do not, so you will need to have your old headlight bulbs replaced if you decide to use them.
To replace the old bulbs properly, you will have to remove the grille from your car using a grille removal tool.
Then, use a pair of pliers to pull out the necessary wires to remove the old light bulbs and replace them with the new ones.
The great thing about aftermarket headlights is that they’re designed to be more durable and last longer than stock headlight systems.
