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.

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.
