Headlight bulb shopping can be terribly confusing if you do not know which bulb goes into which car. For a long time, a common question that vehicle owners and auto distributors alike ask has been: Is H11 Same as 9006? A reasonable question, since they are both low beam bulbs and often get discussed in conjunction. However, despite their apparent interchangeability, it is important that the distinction be made in the interests of lighting safety and performance.
The DIY car owner, the auto part retail business owner, and the distributor-in-stock-will all suffer from reduced visibility, electrical failures, or, worse, destruction from using the wrong choice of bulb. Therefore, in this article, we are going to clear up the whole aspect so that you can make a good decision relating to the H11 and 9006.
Now, let's see what is h11 headlight bulb? H11 bulbs, being single-filament, are most often used in low beam headlights or fog lights. The design calls for an L-type plug, being very much in demand for use in modern auto lighting systems.
Technical Specifications:
Type: Single beam
Wattage: Usually 55W
Voltage: 12V
Base: PGJ19-2
Color Temperature: Varies with type (Halogen: ~3200K; LED: 6000K+)
Common Applications:
Low beam headlights
Fog lights in sedans, SUVs, and trucks
So what are H11 headlight bulbs used for? Mainly, for emitting wide, low-angle light—perfect for routine driving under light-poor conditions.
Similar to the H11, it's a single-beam bulb for low beam use. But 9006 high or low beam dilemma will puzzle many, don't worry, 9006 is used as a low beam bulb only in most cars.
Technical Specifications:
Type: Single beam
Wattage: Typically 55W
Voltage: 12V
Base: P22d (right-angled plug)
Color Temperature: ~3200K for halogen, 6000K+ for LED variants
Common Applications:
Low beam headlights
Rarely fog lights on vintage vehicles
While H11 and 9006 bulbs may appear to be the same, they have slight but significant differences.
H11: PGJ19-2 base; L-shaped socket
9006: P22d base; also right-angle plug but with differently arranged tab
These differences rule out plug-and-play replacement without adapters or modification.
Both are usually 12V and 55W, so they are very similar in electric power output. But they may be slightly different based on design, according to manufacturers.
The pin locations are different, and that affects whether the bulb will fit into the socket and work correctly.
Both bulbs will be used for low beam but the beam pattern and throw of the light might be slightly different due to internal construction and fixture built.

The short answer to the big question, is H11 same as 9006? Is no, they are not the same. But let's get technical.
Feature | H11 | 9006 |
Beam Type | Single (Low Beam/Fog) | Single (Low Beam) |
Base Type | PGJ19-2 | P22d |
Plug Shape | L-shaped | Right-angle |
Interchangeable? | No (different keying tabs) | No (requires adapter) |
An adapter can be used to install a 9006 bulb in an H11 socket or an H11 bulb in a 9006 socket. But experience only. Improper installation can result in:
Poor beam alignment
Electrical faults
Overheating or housing damage
Safety Tip: Don't take 9006 headlight bulb same as H11 for granted as a plug-and-play install. Even though they might be forced to fit, performance and safety could be at risk.
No, for h11 bulb same as 9006, they cannot be physically interchanged. The bases and locking tabs are different, so certain modifications will be required for it to fit.
Yes, you could connect one to the other using an adapter; however, this is not recommended, unless the bulb specifically indicates that it is for dual compatibility.
Using wrong bulbs or forcibly fitting one can create problems of overheating, misalignment of the beam, and electrical issues. Always use as per OEM specifications for your vehicle.
Here's a quick summary to highlight the most popular bulb types:
Bulb Type | Beam | Base | Common Use |
9006 | Low | P22d | Low beam |
9006 | High | P20d | High beam |
H11 | Low | PGJ19-2 | Low beam/Fog |
The 9006 vs 9005 vs H11 distinction matters most to any shopper buying bulbs—particularly when replacing high and low beam sets or going to LED kits.

No. Although they are used for the same purpose, they are not completely interchangeable because of varying base structures and pin configurations.
Is 9006 the same as H11? No, again. An interchange without change can lead to electrical or optical problems.
Installing the wrong bulb can:
Give you poor light quality
Damage to the headlamp housing
Void your vehicle's warranty
LED conversions are occasionally more tolerant of base variations, many LED kits have flexible connectors or offer adapters. However, carefully review specs. All H11 9006 pairings are not road-worthy or legal.
When purchasing your next bulb, keep the following in mind:
1. Compare the OEM Specifications
Always refer to your car manual or utilize a bulb finder tool for original specs.
2. Socket and Base Type
Bulbs can appear identical but socket types matter. Don't try to jam a bulb into another socket.
3. LED vs Halogen
LEDs offer much better lifespan and light but sometimes may require additional drivers or adapters. LEDs are less cheap and easy.
4. Projector Lens Headlights Upgrade (Optional)
If you’re investing in high-output LEDs, a projector lens setup ensures proper beam focus and minimizes glare, ideal for aftermarket upgrades.
So, is H11 same as 9006? No, they are similar in purpose but differ in design, base, and compatibility. While some adapters and LED kits offer cross-compatibility, it's always best to stick with what’s specified by your vehicle's manufacturer.
No, regardless of whether you are a car owner, part supplier, or car seller, it is advisable to verify compatibility. Do not assume h11 bulb equal to 9006 or is a 9006 bulb the same as a h11 necessarily means an interchanging that is safe.
