Best way to adjust headlights!

Get a 10-inch long Phillips bit for your drill. This bit will reach into both the vertical and horizontal holes needed to adjust the headlights. The adjustment screws have gears that a Phillips screwdriver can turn. Using a long Phillips bit on a drill makes the adjustment quick and efficient, and you will actually see the headlights move. Using a regular screwdriver makes it harder to notice the movement. Hope this helps all Hyundai owners!

  • Aim the driver’s side headlight so the top edge of the beam is level with the short piece of tape, four inches below the top edge of your long piece of tape.
  • Adjust the passenger side headlight in the same way, aligning the top of the beam with the other short piece of tape two inches below your long piece.

Thanks for the tip! I recently used a similar method to adjust the headlights on my Hyundai, and it made a world of difference. The 10-inch long Phillips bit really made the adjustment process much easier and more precise.

That’s a great tip for Hyundai owners needing to adjust their headlights! Using a 10-inch long Phillips bit with a drill ensures you can reach both the vertical and horizontal adjustment holes easily. The gears on the adjustment screws are designed for a Phillips screwdriver, and using a long bit on a drill makes the process quick and efficient. Plus, the visible movement of the headlights makes it easier to ensure they’re adjusted correctly. Thanks for sharing this helpful advice!


  1. Park on a Flat Surface: Choose a level parking spot in front of a flat surface like a garage door or wall.
  2. Level the Car: For accurate adjustment, park the car with no passengers or cargo in the trunk.


  1. Tape: Use masking tape or painter’s tape.
  2. Socket Wrench or Screwdriver: Select the tool that fits the adjustment screws on your car.
  3. Optional: Helper: Having someone assist with turning the headlights on/off and adjusting the seat height can be beneficial.

Adjustment Process:

  1. Measure and Mark the Wall: Measure the distance from headlights to the wall (usually 25 feet) and mark two spots on the wall where the center of each headlight beam should hit.
  2. Turn on Headlights: Ensure the headlights are in low-beam mode.
  3. Locate Adjustment Screws: Find the headlight adjustment screws behind the headlights in the engine bay. Refer to your owner’s manual for guidance.
  4. Adjust Vertically: Use the appropriate tool to turn the vertical adjustment screw. Make small adjustments to align the brightest part of the beam with the horizontal mark on the wall.
  5. Adjust Horizontally (if applicable): Some headlights have separate screws for horizontal adjustment. Align the light cutoff slightly to the right of the vertical mark on the wall for right-hand traffic countries.
  6. Repeat for Other Headlight: Adjust the other headlight using the same process.
  7. Double-Check: Verify both headlights for proper alignment and make any necessary minor adjustments.

Prepare Your Car: Make sure your car is loaded to its typical weight and the tire pressure is correct. Remove any excess weight from the trunk and have someone sit in the driver’s seat if possible.
Find a Suitable Location: You’ll need a flat surface and a vertical wall or garage door. The ground should be level and you should have enough space to park your car 25 feet away from the wall.
Mark the Headlights: Turn on the headlights and mark the center of the headlights’ beams on the wall with tape. You’re looking for the brightest point of the beam.
Back Up the Car: Move your car straight back about 25 feet from the wall.
Adjust the Headlights: Open the hood and locate the headlight adjustment screws. These are usually on top or behind the headlight assemblies. Adjust these screws to align the headlights to the correct height and direction. The top of the most intense part of the beam should be at or just below the center line you marked on the wall.
Check the Alignment: The beams should not point directly forward but slightly downwards and towards the center of the car. This is to avoid blinding oncoming traffic.
Test Drive: After adjusting, take a test drive to ensure the headlights are aimed correctly. The road ahead should be clearly lit without blinding other drivers.
