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.

How should my headlights be adjusted?
- 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 do you activate the Toyota automatic high beams?
The Automatic High Beam automatically switches the high beams on or off depending on the brightness of the lights of oncoming vehicles, streetlights, etc. using a camera sensor that is hidden behind the upper area of the windshield.
Warning:
Use the Automatic High Beam sparingly. Always drive safely, paying attention to your surroundings, and manually activating or deactivating the high lights as needed.
Note:
After about a second, the high beams will automatically come on if all of the following requirements are met:
The high beams will automatically turn off if any of the following circumstances occurs:
In the following circumstances, the high beams may not be automatically turned off:
when there are numerous curves, dividers, or trees along the road that make it difficult to see the cars ahead
If a vehicle using fog lights up ahead is seen without its headlights on, the high beams may be turned off.
The low beams may turn on or stay on as a result of house lights, street lights, traffic signals, lit billboards or signs, and other reflected objects.
The length of time it takes the high beams to switch on or off may depend on the following variables:
the state of the highway (gradient, curve, condition of the road surface, etc.)
The following circumstances could prevent the system from accurately detecting the amount of ambient brightness. As a result, the high beams may flash or dazzle approaching individuals or cars, while the low beams may continue to be on. It is required to manually switch between the high and low beams in this situation.
when the brightness of the environment matches that of the headlights, taillights, or fog lights
when an approaching vehicle’s headlights or taillights are dim, filthy, changing hue, or improperly focused
when often and constantly driving uphill or descending roadways, or when traveling on surfaces that are lumpy, uneven, or harsh (such as stone-paved roads, gravel roads, etc.)
when a sign or mirror with a lot of reflecting material is in front of the car
when a vehicle in front of you has a highly reflecting back, such a container on a truck
when a flat tire, a trailer being pulled, etc. causes the vehicle to title or list.
when the headlights alternate abnormally and frequently between the high beams and low beams
when the driver suspects that pedestrians or other drivers may be dazzled or distracted by the high beams
2. Pull the headlight switch lever back to its starting position, swiftly push it into the high beam position ten times, and then leave it there.
The Automatic High Beam indicator will turn on and off three times if the sensitivity is altered.
The high beam indicator will turn on after the Automatic High Beam indicator has been turned off.
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.
Where should headlights be visible?
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.
What is the cost of changing the headlights?
Headlamp alignment adjustments typically cost between $41 and $52. Between $41 and $52 is the expected labor cost range. Taxes and other costs are not included in this range, nor are your particular vehicle or geographic area taken into account.
The headlight beam pattern is what?
The light that is emitted onto a surface is in your beam pattern. It is produced by the bulb itself, the headlight lens, your headlight housing, or a mixture of all three. The beam pattern is impacted by the type of headlight and bulb you select, presuming you are replacing your OEM parts.
The ideal beam pattern will have crisp cut-off lines at its top and a spread that is large enough to extend somewhat beyond the road. Additionally, there will be distinct hot spots that provide you with quality forward lighting so you can see far into the distance.
Examples of Good Beam Patterns
This illustration is from a Morimoto XB LED headlight that is entirely LED. It is a flawless illustration of an excellent headlight beam pattern. With this light, the pattern has a wonderful form, tremendous width, great light dispersion, and extremely clear cut-off lines. The light’s power cannot blind approaching cars because of this form.
However, not everyone who reads this has a car that Morimoto sells a headlight housing for. Some readers are simply looking to improve their lights and encourage safe driving.
A decent beam pattern for projector headlights with the stock halogen bulb installed will resemble the image below. Although the brightness is obviously far lower than that of the Morimoto offering, the XB LED headlight beam pattern is physically identical.
Here is an illustration of an LED bulb in a housing for a reflector. While not the best, this beam pattern is still quite impressive. The pattern doesn’t shine as brightly as the XB LED headlamp, just like in the other sample we looked at. This one doesn’t have much width either.
Here is a bad headlight beam pattern as an example. With regard to the hot spots and beam spread, it is evident that they are cohesive or lack a defined form.
Aiming Your Headlights
You might need to re-aim your headlights if they don’t resemble any of the lights we just examined. The only other possibility is that your headlights are of poor quality or that the bulb you are using is incompatible with the housing of your headlights.
Equipment Required for the Job: Measurement tape, masking tape socket wrench or screwdriver a wall
Step 1: Pull up to the wall from a distance of about three feet, leaving some room between your front bumper and the actual wall.
If only one person regularly operates the car, you’ll want to ensure that someone is seated in the driver’s seat while you’re aiming. You should simulate that for this as well if your car is regularly loaded down with big equipment. Have around half a tank of gas in your car if you want to be exact about this.
Step 2: Determine the center of the car and mark it with a vertical piece of painter’s tape or another marking material. Add another vertical piece of tape to the wall in front of each headlamp after locating its center.
You’ll want to confirm that the distance between the headlight marker and the middle of the wall is the same. The small depression in the plastic that marks the center of your headlamp can be used to locate it.
Step 3: Use a tape measure to measure the distance between the ground and the center of your headlamp. The height of the dimple on your headlight as measured from the ground up is this value. Make a mark on the tape after measuring the distance up to it on the wall. That should properly locate the headlight’s center on the wall.
Make a mark and measure down two inches as well. Just above the bottom mark, attach a horizontal strip of tape across the surface. Likewise for the other headlight.
Step 4: Check that you have enough space and back 25 feet from the wall. Manufacturers may specify various closer or farther distances. Check your owner’s manual to be sure you’re performing the task correctly before attempting it yourself.
Your headlight beam should stop at the cross mark we drew on the wall once you have reversed far enough.
Before it has been correctly directed, this is how the headlight beam pattern appears. We came close, but not quite far enough.
5. Locate the adjustment screw to change the height of your headlights if it is incorrect, and make the necessary adjustments using a screwdriver or socket wrench.
You can see how the beam pattern has been adjusted to match the measurements we made on our wall in this picture.
