- Make that the area of the body surrounding the headlights is intact and not damaged. refuel the vehicle.
Tires should be inflated to the proper pressure. Reposition the jack, tools, and spare tire in their original locations. Open the trunk.
2. SET UP HEADLIGHT AFFINITY (Using a tester)
3. SET UP HEADLIGHT AFFINITY (Using a screen)
(a) Get the car ready under the following circumstances:
- Put the car in a spot where you can see the cutoff line clearly in the darkness. The cutoff line is a clearly defined line below which headlight illumination is visible and over which it is not.
- Put the car at a 90-degree angle to the wall.
- Set a space of 7.62 m (25 ft) between the car’s headlight center and the wall.
- Position the car on a level surface.
- To adjust the suspension, bounce the car up and down.
NOTICE:
For correct aim adjustment, there must be 7.62 m (25 ft) between the car’s (headlight bulb center) and the wall. If not available, reserve a space of precisely 3 m (9.84 ft) for inspection and correction. (Follow the instructions in the example because the target zone will change depending on the distance.)
(b) Create a screen out of a piece of thick white paper that is approximately 2 m (6.6 ft) in height by 4 m (13.1 ft) in width.
(d) Arrange the display as it is in the illustration. HINT:
- Place the screen vertically on the floor.
- Set the screen’s V line so that it coincides with the vehicle’s center.
The alignment gap is 7.62 m (25 ft) wide:
3 m (9.84 ft) is the alignment distance:
(f) On the screen, draw the basis lines (H line, V LH, and V RH lines) as shown in the illustration.
HINT:
- For “low-beam inspection” and “high-beam inspection,” the base lines are different.
- Mark the screen’s center with the headlight bulb’s marks. Use the center of the headlight bulb or the manufacturer’s name inscribed on the headlamp as the center mark if the center mark on the headlight cannot be seen.
First, the H Line (headlight height)
Draw a horizontal line through the center of the marks on the screen. The low-beam headlights’ headlight center marks and the H line should be at the same height.
(2) V LH Line, V RH Line (Left-Hand (LH) and Right-Hand (RH) Headlight Center Mark Position): At each center mark, draw two vertical lines such that they cross the H line (aligned with the center of the low-beam headlight bulbs).

INSPECT HEADLIGHT AIMING
To prevent light from the headlamp not being inspected from disrupting the headlight aiming inspection, (a) cover or disconnect the connector of the headlight on the opposite side.
Never cover the headlight for longer than three minutes. The synthetic resin used to make the headlight lens is prone to melting or other heat-related damage.
Cover the low beam or unplug the cable to check the high beam’s aim.
(c) With the headlamp on, check to see that the cutoff line is within the boundaries of the illustration’s indicated area.
High Beam:
Low Beam:
- Given that the low-beam and high-beam lights are one unit, if the aim on one is accurate, the other should be as well. To be certain, check both beams though.
With low-beam, the cutoff line is 101 mm (3.97 in) high and low, and left and right of the V line (SAE J599).
In low-beam applications, the cutoff line is 40 mm (1.57 in) above and below the H line as well as to the left and right of the V line (SAE J599).
When using high-beam, the cutoff line is 101 mm (3.97 in) to the left and right of the V line, as well as above and below the H line (SAE J599).
When using a high-beam, the cutoff line is 40 mm (1.57 in) above and below the H line as well as to the left and right of the V line (SAE J599).
5. CHANGE HEADLIGHT POSITIONING
(a) Vertically adjust the aim:
By using a screwdriver to turn aiming screw A, you can change the headlight’s aim to fall within the designated area. NOTICE:
The aiming screw should be turned clockwise for the last time. If the screw is overtightened, loosen it first, then tighten it again so that the final spin is counterclockwise. HINT:
- Adjust the low beam’s aim.
- When the aiming screw is turned clockwise, the headlight aim moves upward, and when it is turned counterclockwise, it moves downward.
- Both screws on a discharge headlamp should be turned in the same direction and by the same number.
How far up should I point my headlights?
Your vehicle’s ride height can be subtly altered by suspension issues or a large cargo load, which may also cause one or both headlights to move. Your lights may become out of alignment as a result of a collision or running over a road obstruction.
Parking the car on a level surface and shining the headlights on a wall or garage door 25 feet in front of you can help determine whether the headlights are accurately aimed (some cars may require a different distance). For the majority of vehicles, the top of the low beam that shines on the wall should be at or just slightly below the height of the center of the headlight lens. You can anticipate that the light pattern will be lower on the driver’s side to avoid blinding other cars and higher on the passenger’s right side to highlight traffic signs. This should help you determine whether the beams on both sides are pointed in the right directions.
Another approach is to park the car five feet from the wall and then mark the wall’s vertical and horizontal light beam centers with masking tape. Reposition the car 25 feet back. The light beams should be around the same height both vertically and horizontally with the help of the tape line.
For adjusting headlight height, vehicles typically feature a screw or bolt on the headlight assembly. Some vehicles additionally include a screw for adjusting horizontal aim. A bubble level is also included in some cars to aid in modifications.
Without taking apart components like the battery, you might not have much room or even be able to reach the adjusters on some vehicles. Additionally, the vehicle must be perpendicular to the surface you’re shining the headlights on, be on properly level ground, and have no damage to the suspension system, flat tires, or baggage that would impact the ride height.
The owner’s manuals of many vehicles offer scant or no advice on headlight aiming. Ask a repair business to check if you’re unsure. A dealership may inspect the headlight aim and align it for free if the car is still under the basic warranty.
View the video below for a visual representation of everything mentioned above. Additionally, remember to regularly clean your headlights.
How can headlamp alignment be checked?
You must first determine whether the headlamp alignment is correct and whether it has to be adjusted. This can be done in a few simple steps.
Remove any extra weight first, such as objects in the boot, as these could cause your reading to be off. Additionally, make sure your tires are inflated to the pressure recommended by the manufacturer. Once parked, keep your vehicle around 60 cm from any walls or garage doors.
Now you can turn on the headlights, making sure they are not set to the beam or the fog light settings but rather the regular option. On the wall, the headlights will appear as a circle. Use two pieces of tape or a pencil to draw a plus symbol on the wall. Both lines should run horizontally from side to side and vertically from the top of the circular to the bottom. The center of your headlights is where the two lines converge in the middle.
Use a tape measure to make sure the plus signs’ centers are the same height. If they aren’t the same height, you might need to decrease one plus sign.
Reverse your automobile so that it is around eight meters from the wall once you are satisfied with your marks and they are both the same height. You don’t need to modify anything if the middle of your headlights still falls within your marks. You must readjust your headlights if they are dropping above, below, or to the side of the plus symbols.
How do I manually change my headlights?
- Read the owner’s manual. Some automobiles don’t have a headlight adjusting feature. To find out whether your specific make and model allows for adjustment, examine the owner’s handbook. To find out where the adjusting screws are located, you need also consult the handbook. Similar to a carpenter’s level, certain automobiles contain leveling bubbles that aid in headlight adjustment. You may find the kind and placement of the adjustment screws in your owner’s handbook.
- Put the automobile on a level spot. Find a flat area where you may beam the headlights on a wall or a garage door. Make sure the car’s tires are properly inflated, that the petrol tank is at least halfway full, and try to simulate the weight that you would typically carry inside the automobile. Turn on the headlights while applying pressure to the car’s four corners to assist in balancing the shocks.
- Establish a central axis. It is better to complete this following stage at dawn or dusk. The distance between the car and the wall should be six feet. the low beam setting on your headlights. As the beam shines on the wall, use the masking tape to identify the horizontal and vertical axes of the beam. The tape should be placed such that it forms a cross.
- The difference between the two headlights should be measured. Check to determine if both headlights have the same measurement by using the measuring tape to measure the lines. The tallest centerline should be lowered to be the same height as the lowest centerline mark if the measurements don’t line up. Some cars have incorporated crosshairs in the headlight that make it simple to locate the beam’s center. This information can be found in your owner’s manual.
- Car is being backed away from the wall. Measure the area using the measuring tape at the approximate 25-foot distance suggested by your owner’s manual. Back the car up until the front wheels are at the 25-foot mark while maintaining a level surface. Turn on your headlights and observe where the marked area on the garage wall is struck by the brightest portion of the headlight’s beam.
- Get ready for the change.
- Remove the headlights’ ring or bezel to make way for the adjustment, keeping the pieces safely stored away. Make sure you have a screwdriver on available, along with some dark cardboard or fabric. Know where the vertical and horizontal adjuster screws are located. The actual adjustment operation is made easier with a helper inside the vehicle.
- Vertical field should be adjusted. Have the helper turn off the headlights while you are standing in front of the vehicle. Next, have the assistant switch on one headlight while you cover the other with the dark cloth or cardboard. Locate the adjusting screw and slowly move it in either the clockwise or counterclockwise direction to change the height of the lights. Ensure that the most intense portion of the headlight beam strikes at or just below the vertical centerline you marked with tape on the wall when you make your adjustment.
- the horizontal field, as necessary. To move the headlights inward or outward, turn the screws in either a clockwise or counterclockwise direction. Just to the right of the middle tapeline, the headlight beam should land. After making the necessary vertical and horizontal adjustments to the other headlamp, block out the modified headlight.
- Adjustments should be refined. Once the center axis of the headlight beam coincides with the tape marks on the wall, continue fiddling with the vertical and horizontal adjustments. Take the car for a test drive when you’re satisfied with the modifications, and if one of the headlights isn’t quite up to pace, repeat the steps above.
How far should your low beam headlights project?
Depending on the headlights you’re using, your headlights should shine a certain distance. High beams or brights should shine 350 to 400 feet in the distance, while low beams or dipped lights should shine roughly 150 to 200 feet away. For maximum effectiveness, fog lights must be positioned at a specific height; they do not need to illuminate the road in front of them.
Read on to find out everything you need to know about how far your headlights must shine, including how to examine each type, align them, and more!
How Far Should Your Headlights Shine While on High Beam (Brights)?
High beam headlights, sometimes referred to as brights, should illuminate the road in front of you for approximately 350400 feet (107122 meters).
High beams are advised for when you’re travelling quickly, thus this is roughly twice the distance needed for conventional headlights.
How far should your headlights project when they are on high beam?
When it is dark enough to not be able to see enough of the road ahead to drive safely, high beam headlights should be utilized.
Even the most seasoned drivers may find nighttime low visibility frightening. Why is nighttime driving riskier? A driver’s acute visionwhich includes depth perception, color identification, and peripheral visionis responsible for 90% of their reactions, all of which are significantly impaired at night. Headlights with high beams shine at an angle, illuminating the road 350400 feet in front of the vehicle, or nearly twice as far as low beams. (Remember that 100 feet per second is equal to 68 miles per hour. Low lights may only offer you a few seconds to react to a hazard when driving at highway speeds at night.)

High lights can help keep you safe but, if used improperly, they can also put other drivers in risk. Whenever there is a chance that you might blind other drivers, you are required by law in every state to lower your high beam headlights. In general, high beam headlights cannot be utilized within 500 feet of an approaching vehicle or within 200 to 300 feet of a vehicle you are following. The exact distance varies from state to state.
