I simply pressed my hands together behind the lights to remove the lightbulb after removing the rubber boot off the plug and two metal prongs on the sides. then snap seal back on and pop clip back into plug harness back up. Passenger probably had more space and could view it better because it was hard to see. If I recall correctly, drivers are the cause of the fuse box and airbox.

H4 LED headlight: what is it?
In the past, H4 bulbs served as the majority of the lighting in cars. These are referred to as bilux lamps. Simply said, this indicates that the bulb has two filaments: one for the low beam and one for the high beam.
One filament illuminates when the low beam is turned on, while the other illuminates when the high beam is turned on. When the low beam is turned on, the light cone is thrown in front of the vehicle; when the high beam is turned on, the light cone is thrown further ahead. The reflectors in the headlamp are precisely adjusted to the location of the filaments in the lamp. Halogen bulbs are now frequently used in modern H4 lights.
An H4 system has the following characteristics:
- The bulb housing of the lamp contains two filaments.
- In the headlamp, there is just one lamp base plate available.
Describe an HIR2 bulb.
CI1255 HIR2 halogen bulbs are frequently found on Lexus and Toyota automobiles. The UV-reduced HELLA halogen automobile bulbs are secure for use in contemporary headlamps with polycarbonate lenses.
How do I adjust the headlight level?
- 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.
What is the ideal distance between 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.

Is H7 superior to H4?
The 180W headlight kit or two 90W headlights are installed in both headlights. They will provide highly effective, extremely bright light that will improve nighttime vision. The COB chip, or Chip on Board, used in the H7 headlamp is a relatively new advancement in LED technology. Compared to SMD, this makes it possible to create a denser light array that emits a clear, bright light.
The H4 LED headlights have a lifespan of up to 50,000 hours, whilst the H7 headlights have a lifespan of only 30,000 hours. Apart from the lifespan, both of them start to glow right away when powered on. They don’t always require a few minutes to reach the full brightness of it. Clear light will be produced by these LED headlights, and the spaces they shine into will be perfectly sliced. As opposed to halogen lighting, which typically has intense light in the center and gradually diminishes toward the edges.
These two headlights are water-resistant as well. The H4 headlight can endure rain or other damp conditions because it has an IP65 waterproof rating. On the other hand, the H7 headlamp has an IP7 waterproof rating, allowing it to be submerged underwater and still function well.
These two headlights will use less power than other headlights because they are both LED. Because of this, it is a better option in terms of long-term cost savings. These two types of headlights will undoubtedly give you the optimum lighting for nighttime driving, depending on which one best suits you.
H7 uses a high or low beam.
Autos have traditionally employed dual-beam bulbs. By changing the reflecting pattern, a single housing with a single bulb may switch between a high and low beam. So to say, a two-in-one light bulb.
However, more recent vehicles use two distinct single-beam bulbs for each purpose. The car’s headlights are then equipped with two bulbs, one on each side of the car.
Each of these beams uses either an H1 or a H7 bulb, as you would have guessed. And this is where the H1 and H7 bulbs differ from one another.
The high-beam light is produced by the H1, while the low-beam light is produced by the H7.
Both the H1 and H7 are single-beam lamps that produce a fixed beam using a single filament.
This headlight is mostly used on open motorways and at night on country roads; it is not always used.
The H7 beam’s shorter range makes it suitable for lighting the road ahead of the car.
Which vehicles will a H7 bulb fit?
You don’t have many options when it comes to the bulb fitting when buying new headlight bulbs. Your vehicle determines the type of bulb required. Several BMW, Audi, and Mercedes models, as well as many others, use H7 bulbs as headlights.
Using the bulb finder on our home page, you may identify the appropriate bulb fitting for your car. Check out our assortment of halogen H7 bulbs, which are ideal for headlights if your car needs them. We also have LED H7 bulbs if you want a fashionable aesthetic that is probably not street-legal.
