It’ll be a headache to drive your JK with unadjusted headlights at night. You won’t have a clear vision of what is on the road. As a result, you may face accidents while traveling at night.

Blurry Headlights

Damaged Shocks

Defective shocks are another prime reason behind adjusting the headlights. The front of the JK stays lifted if the front shocks are poorly damaged. 

As a result, it covers the headlights. Installing new shocks than adjusting the headlights solves the problem faster.

Car Crash

If your JK crashed face to face with another vehicle, there’s a high possibility that the headlights will come out of their place. So, you must adjust the headlights ASAP.

An imbalance of tire pressure can also cause maladjustment of headlights. While driving on a rough surface, the ride can get bumpy. Consequently, a bumpy ride imbalances the headlights and causes blurry light issues while driving.

The 3 Feet Phenomena

Most jeeps have soft springs. So, when you put any weight on the jeep, the jeep’s height changes significantly. Therefore, you must adjust the headlights if you’re using a heavy front bumper.

Step 01: Jeep Parking

Jeep parking covers many steps. We’ve divided them into small steps for you to understand easily.

  1. Park your Jeep JK facing a wall. 
  2. Then calculate a 20 feet distance and label it.
  3. Now, take the JK to the marked spot and park it facing the wall again.
  4. Remember, the headlights should be 20 feet away from the wall.
  5. Select a flat parking surface to put the tires on the same height.

Step 02: Label 3 Feet

Use the sticky tape to mark 3 feet on the wall from the driver’s side. Next, follow the same procedure from the passenger’s side. 

Then, connect these two spots using the long tape. The long tape line indicates the 3 feet’ height from the ground.

Step 03: Headlight Adjusting

Well, you’re halfway done. Now that you’ve parked your JK 20 feet away from the wall and faced the wall follow these crucial steps to adjust the headlights.

  1. Use a torque screwdriver to adjust the corner headlight screws. Turn the screwdriver clockwise to loosen up the headlight and turn it counterclockwise to tighten them up.
  2. The screws are placed outside of the headlight in the Jeep JK model. Fix up the screws with the screwdriver.

Step 04: Alignment

Now that you’ve adjusted the lights, you must fix the JK’s beam. Follow the joined 3 feet tape line mark to adjust the beam. Voila! You’ve adjusted the headlights of your JK.

The Alternate Method

It’s the same method as the previous one, but some steps differ. Here are the steps you must follow to adjust your jeep JK’s headlight.

Step 01: Calculate Headlight Heights

Park your Jeep JK 20 feet away from the wall the same way following the first method. 

Now, calculate the height to the center of the headlights from the surface. Then, decrease the length by 2″ and mark the measurement on the wall with sticky tape.

Step 02: Adjust The Headlights

Use the torque screwdriver to adjust the headlight’s screw following the previous strategy.

Step 03: Align The Beam

Again, use the screwdriver to balance the beam. Balance the shaft to the decreased 2″ length marked on the wall. Apply enough force if you fail to align the beam correctly.

Step 04: Inspect

Check out the headlight’s light after you’ve completed the procedure successfully. Contact an experienced mechanic if you fail to adjust the beam correctly.

Cost Of Adjusting Jeep JK Headlight

It won’t cost a penny if you can adjust the headlights yourself. However, you might lose some screws while fixing it. Then, it becomes a pain to find the screws and modify them.

If you’re considering appointing a mechanic to adjust the JK’s headlight, he’ll charge you $35 to $44 on an average day. The adjusting screws will cost you $3.59 each. Sticky tapes for marking won’t cost you more than a dollar.

On the other hand, a long tape might cost you around $3.9 to $7.9, depending on its quality and warranty. So, the total sum stands between 40 to 55 bucks.

What will you do if you’ve damaged the headlights while adjusting them? In this case, you must replace the damaged headlights with new ones. You can buy new headlights for $65 to $100 if you’re on a tight budget. But if you want high-end JK headlights, you must pay up to $800.
