The last thing you want when driving after the sun sets is for your headlights to blind oncoming vehicles or alert extraterrestrials from another galaxy. You may not mind if your cosmic counterpart pays you a visit, but at the very least, show some consideration for other drivers and adjust your headlight beams. No of the model year, your Tacoma has a pair of adjustments on each headlight assembly to assist you in providing that courtesy.
Setting up your Tacoma such that you can adjust the headlights appropriately is the most difficult part of the process. Find a level parking space with a wall or building that you can access to get started. You must have a clear line of sight to the wall and be able to park 25 feet away from it.

Items you will need
Your front tires should be aligned as you approach the wall. Find the pointing nipple that is right in front of the headlight bulbs by looking at the lenses of your headlights. Calculate the distance between the ground and the nipple’s center. The distance between the left and right headlights’ central aiming nipples should be recorded.
Create two 2-inch circular marks on the wall in the exact locations of the center aiming nipples. Make sure the marks are the same height and spacing apart as the center marks on the headlight lenses by using the measurements you took in the previous step. Make a 7.94-inch horizontal and vertical line that passes through the circles and intersects at their centers. Four 3.97 by 3.97-inch cubes should be drawn around each circle by boxing in the cross you just made.
Mark the concrete at 25 feet from the wall. Back up until the front bumper tip of your Tacoma is directly over the concrete mark you established while maintaining straight wheels; at this point, you can begin making changes.
The adjustment gears or screws on the back of the headlamp assembly should be identified. The vertical adjustment screw is located at the 8 o’clock position on the driver-side headlight and the 4 o’clock position on the passenger-side headlight, if you are looking squarely at the back of the headlight assembly. The driver-side headlight’s horizontal adjustment screw is located at 11 o’clock, while the passenger-side headlight’s is located at 1 o’clock.
Tips
- For the horizontal and vertical adjustment screws, some Tacomas use a 4mm bolt, while others use a little gear that you spin with a Phillips screwdriver.
- Small rubber caps may be used to cover the screws. To reveal the gear or 4mm screw head, merely remove the caps.
Turn on the headlights after removing the electrical harness from one of them. The headlight beam can be adjusted vertically by turning the screw either clockwise or counterclockwise. The four corresponding squares you created on the wall should contain the top of the headlight beam. Once the height is chosen, rotate the horizontal screw in either a clockwise or counterclockwise direction to adjust the headlight beam inward or outward.
To lock in the adjustment, each adjuster must be turned completely counterclockwise.
Put the headlights off. Connect the wire harness to the other headlight after disconnecting it from the headlight whose wiring you’ve just changed. Repetition of the correction process Before connecting the wiring harness, turn off the headlights. Any rubber covers that might have been on the adjustment screws should be replaced.
How do I correctly adjust 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.
Are the headlights on the Toyota Tacoma automatic?
The premium package for the 2019 Toyota Tacoma includes automated headlights. When an ambient light sensor determines that it is too dark outside, automatic headlights are intended to turn on. You can avoid the inconvenience of having to remember to turn on your headlight switch by doing this.
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 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 brightly should I set 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.

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.
How much does aligning headlights cost?
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.
