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.

What should the range of my headlights be?
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 350–400 feet (107–122 meters).
High beams are advised for when you’re travelling quickly, thus this is roughly twice the distance needed for conventional 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.
What distance should your high lights be visible?
A brilliant glow is produced by high beam headlights that can be seen up to 350–400 feet in front of your car. That roughly equals the length of a city block. High beams are excellent for nighttime driving in rural regions or on dimly lit highways because they are pointed directly in front of you.
High beams aren’t the best option for city driving, either, as their brightness and location can lead other vehicles up to 150 meters away from you to get blinded.
How should a driving light be pointed?
Calculate the distance between the auxiliary light’s center and the ground. Make a horizontal mark at that height on the wall. At a distance of 25 feet, with the lamp facing forward, a visual aim is made with the center of the driving beam hot spot 1.5 inches below the light’s center.
How should LED headlight bulbs be oriented?
What orientation should my LED bulb face is one of the most frequent queries we receive each day. In contrast to halogen lights, which emit light in all directions, LEDs are “directional light sources,” meaning they emit light in a particular direction. In addition to the potential for glare on other drivers, the light will otherwise look to have a poor output or beam pattern. Because headlamps have varied optical designs, LED bulbs need to be positioned precisely.
Diodes (LED chips) for single filament bulbs should always be oriented side to side, with one set of LEDs facing at 3 o’clock and the other set facing at 9 o’clock. This will allow for a nice, even 360-degree light dispersion throughout the housing, producing a light beam that is both well focused and fully filled.
We will employ the same side-to-side arrangement for dual headlamp configurations that produce both low and high beams from a single bulb. For dual beam bulbs, there are two sets of LED chips on either side of the bulb, and the two chip sets must be aligned as shown in the image below.
Important Information: Most of the time, each bulb is installed with the best operating angle, thus adjusting them is not always necessary. Before any harness is connected, check the LED lights’ alignment as soon as you have them installed. For information on how to modify the angle of the bulbs, please refer to the LED Bulb Adjustment Guide.
Why are there shadows in my headlights?
I don’t think it’s really a problem, more like it’s been set up that way. The beam has a dip in it to lessen glare for approaching drivers. All projector-based headlight systems make some form of dip, but the majority simply remain to the left.
In order to prevent the dip on each light from overlapping, you can move the headlights from side to side if this bothers you. If you do this, you will end up creating additional glare for approaching vehicles, therefore you should also point them slightly downward.

How far should low beams be projected?
The following determines whether to use high- or low-beam headlights:
About 200 feet, or half a city block, of the road is illuminated by low-beam headlights. High beams should be used when you can no longer see more than 200 feet in low beams, unless:
200 feet away and coming at you from the opposite direction is another automobile.
When used in poor weather, high lights can produce glare and become dangerous. And you should return to using low beams if using high beams could cause someone to get blinded on or near the road. However, in general, when there are no other vehicles around and the weather is good, you should use your high lights on both city and rural routes at night.
What is the cost of changing the headlights?
Headlamp alignment adjustments typically cost between $40 and $51. Between $40 and $51 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.
With low beams, how far should you be able to see?
Two headlamp settings are available for usage in various circumstances.
high beams and low beams (dimmed headlights) (bright headlights). Depending on your speed and visibility, using the incorrect type of headlight setting can be disastrous and cause an accident.
As a motorist, it is your obligation to be aware of when to use low and high beams.
How Far Can You See With Low Beams?
- High-beam headlights are appropriate for speeds more than 25 mph and provide visibility out to around 350 feet. Only certain circumstances should call for the usage of the high-beam setting (read more here).
- Low-beam headlights are ideal for speeds up to 25 mph and provide visibility for roughly 200 feet. The “dimmed” or “dipped setting is another name for the low-beam setting.
In essence, low beams at night emit significantly less light than high beams. When traveling at speeds greater than 25 mph at night while using low beam headlights, it can be too late to stop before colliding with an item.
Since low beams are much weaker than high lights, they can be employed without endangering other drivers’ vision.
You must switch to high beams when you require more light than low beams can offer (if legal). Keep in mind that while high beams will help you see wider in front of you, improper use of them risked blinding other motorists.
Should headlights be aligned?
It’s crucial to have good headlights to illuminate your path. When it comes to car ownership, many owners forget or outright disregard the fact that those bulbs are useless if they are not adequately pointed at the road.
The alignment of a car’s headlights can change over time or even with a simple bulb replacement. Reduced visibility, which is a major issue when driving at night, could result from this. If anything darts onto the road when you’re moving at 60 mph, you have just seconds to prevent a crash. Misaligned lighting can cause you to lose all reaction time.
Where are headlamps pointing?
The visually optically aligned (VOA) systems come in two different subtypes: visually aligned left (VOL) and visually aligned right (VOR) (VOR). The severe cutoff of the light pattern on the left of the lamp is directed toward a vertical aiming plane when VOL headlamps are pointed in that direction. The right side of the beam is used as the reference point when aiming VOR headlamps. A vertical aiming plane for VOL systems is located 0.6 below the alignment board’s vertical reference point. A vertical aiming plane for VOR systems is located at the same height as the reference point. The targeting planes are shown in figures 7 and 8.
