A common topic in the headlight world is: H9 vs H11. The H9 and H11 headlight bulbs are two of the most popular options on the market, and they’re often used interchangeably in vehicles. While they may look similar, there are some key differences between the two that you should be aware of before choosing which one to use in your vehicle.

H9 vs H11 Key Differences

Beam Type

First, let’s take a closer look at the H9 and H11 bulbs themselves. Both bulbs are halogen bulbs, which means they use a filament inside a gas-filled glass bulb to produce light. The H9 bulb has a single filament design, with one coil of wire inside the bulb that produces both low and high beam light. The H11 bulb, on the other hand, has a dual filament design, with two separate coils of wire inside the bulb that produce low and high beam light separately.

Size & Shape

One of the main differences between the H9 and H11 bulbs is their size and shape. The H9 bulb has a length of 2.56 inches and a diameter of 0.94 inches, while the H11 bulb has a length of 2.75 inches and a diameter of 1 inch. This means that the H11 bulb is slightly longer and wider than the H9 bulb, which can make it more difficult to install in some vehicles.

Light Output

Another key difference between the H9 and H11 bulbs is their light output. The H9 bulb has a rated output of 1,200 lumens on the low beam and 1,500 lumens on the high beam, while the H11 bulb has a rated output of 1,100 lumens on the low beam and 1,300 lumens on the high beam. This means that the H9 bulb produces slightly more light than the H11 bulb, which can make it a better choice for drivers who need extra visibility on the road.

Headlight Housing Design

In terms of compatibility, the H9 and H11 bulbs are both commonly used in a wide range of vehicles. However, some vehicles may be designed specifically for one type of bulb over the other. For example, some vehicles may have a headlight housing that is too small to fit the H11 bulb, while others may have a headlight socket that is not compatible with the H9 bulb. It’s always a good idea to check your vehicle’s owner’s manual or a repair manual to find out which type of bulb is recommended for your vehicle.

Frequently Asked Questions:

H9 headlight bulb fits what cars?

The H9 headlight bulb is a popular option that is commonly used in a wide range of vehicles. However, it’s always a good idea to check your vehicle’s owner’s manual or a repair manual to determine if the H9 bulb is compatible with your vehicle. You can also use the Sylvania Bulb Guide to look up the lights that fit your vehicle.

In general, the H9 bulb may be a good fit for vehicles that have a headlight housing with a diameter of 0.94 inches and a length of 2.56 inches, and a headlight socket that is compatible with a single filament bulb. Some examples of vehicles that may be able to use the H9 bulb include:

  • Audi A3
  • BMW 3 Series
  • Chevrolet Silverado
  • Ford F-150
  • Honda Civic

This is not a comprehensive list, and there may be other vehicles that are compatible with the H9 bulb. Again, it’s always best to check your vehicle’s owner’s manual or a repair manual to be sure.

Is H9 the same as H11?

No, the H9 and H11 headlight bulbs are not the same. While they may look similar and are often used interchangeably in vehicles, there are some key differences between the two bulbs.

The H9 bulb has a single filament design, with one coil of wire inside the bulb that produces both low and high beam light. The H11 bulb, on the other hand, has a dual filament design, with two separate coils of wire inside the bulb that produce low and high beam light separately. This means that the H11 bulb is capable of producing two different levels of light output, while the H9 bulb has a fixed output.

Another key difference between the H9 and H11 bulbs is their size and shape. The H9 bulb has a length of 2.56 inches and a diameter of 0.94 inches, while the H11 bulb has a length of 2.75 inches and a diameter of 1 inch. This means that the H11 bulb is slightly longer and wider than the H9 bulb, which can make it more difficult to install in some vehicles.

In terms of compatibility, the H9 and H11 bulbs are both commonly used in a wide range of vehicles. However, some vehicles may be designed specifically for one type of bulb over the other. It’s always a good idea to check your vehicle’s owner’s manual or a repair manual to determine the recommended type of bulb for your vehicle.

Overall, while the H9 and H11 bulbs are similar in some ways, they are not the same. The H9 bulb has a single filament design and a compact size, while the H11 bulb has a dual filament design and a slightly larger size. The best choice for your vehicle will depend on your specific needs and the characteristics of your vehicle.

If you need to handle a headlight bulb, it’s best to use gloves or a clean cloth to avoid contaminating it with oil from your skin. If you do accidentally touch the bulb with your bare hands, you can try wiping it down with rubbing alcohol to remove any oil that may have transferred to the bulb.

How to take a headlight bulb out?

The process for removing a headlight bulb can vary depending on the make and model of your vehicle. In general, the steps for removing a headlight bulb are as follows:

  1. Open the hood of your vehicle and locate the headlight assembly.
  2. Depending on your vehicle, you may need to remove a plastic cover or other protective casing to access the headlight bulb. Consult your owner’s manual or a repair manual for specific instructions on how to remove the protective casing on your vehicle.
  3. Once you have access to the headlight bulb, look for the electrical connector that attaches the bulb to the vehicle’s wiring harness.
  4. Carefully unplug the electrical connector from the headlight bulb. Some connectors may have a release tab that you need to press in order to unplug the connector, while others may simply pull straight out.
  5. Once the electrical connector is unplugged, you should be able to twist the headlight bulb to release it from the headlight housing. Be careful not to touch the glass part of the bulb with your bare hands, as the oil from your skin can contaminate the bulb and cause it to overheat.
  6. Once the headlight bulb is released from the headlight housing, you can carefully remove it from the vehicle.

Keep in mind that the exact process for removing a headlight bulb can vary depending on your vehicle. It’s always a good idea to consult your owner’s manual or a repair manual for specific instructions on how to remove the headlight bulb on your particular vehicle.
