What is the difference between H11 and 9006 bulbs?
When it comes to automotive lighting, choosing the right bulb for your vehicle is crucial for safety and performance. Two commonly used bulb types are H11 and 9006. While they may look similar at first glance, they have distinct differences in design, application, and compatibility. In this article, we’ll break down the key differences to help you make an informed decision.
1. Bulb Design and Connector Type
The H11 and 9006 bulbs differ in their physical design and connector types, which makes them incompatible with each other without modifications.
- H11 Bulbs: These are single-beam bulbs, typically used for low-beam headlights or fog lights. They have an L-shaped connector and a specific tab alignment that ensures they fit only into H11-compatible sockets.
- 9006 Bulbs: Also single-beam bulbs, 9006 bulbs are commonly used for low-beam headlights. They feature a straight connector and a different tab alignment compared to H11 bulbs.
2. Wattage and Brightness
Another key difference lies in their wattage and brightness output, which can affect their performance and energy consumption.
- H11 Bulbs: Typically rated at 55 watts, H11 bulbs are designed to provide a bright and focused beam, making them ideal for low-beam applications.
- 9006 Bulbs: These bulbs are also rated at 55 watts but may have slight variations in brightness depending on the manufacturer. They are known for their efficiency and reliability in low-beam settings.
3. Applications and Compatibility
H11 and 9006 bulbs are designed for specific applications, and their compatibility depends on your vehicle’s headlight housing and wiring.
- H11 Bulbs: Commonly used in modern vehicles for low-beam headlights or fog lights. They are not interchangeable with 9006 bulbs due to their unique connector and tab design.
- 9006 Bulbs: Often found in older vehicle models for low-beam headlights. While they share a similar wattage with H11 bulbs, their connector and tab alignment make them incompatible without adapters or modifications.
4. Can You Use Them Interchangeably?
In short, no. H11 and 9006 bulbs are not directly interchangeable due to their differences in design and connector types. Attempting to force one into the other’s socket can damage the bulb or the headlight housing. If you need to switch between these two types, you’ll require an adapter or conversion kit, but this is not recommended unless absolutely necessary.

What vehicles use a H11 bulb?
There are several vehicles that fit these bulbs, for instance, Acura models including Cl, ILX, Integra, MDX and RDX models. It also fits in Audi A6, A8, and S6 models alongside Cadillac models such as Deville, Eldorado, Escalade, EXT, Seville, SRX, and STS models.
Is 9006 a low or high beam?
Primary Usage. The 9005 bulb is mainly used for high beams, offering brighter and more direct light. On the other hand, the 9006 bulb is primarily used for low beams, providing wider and less intense illumination.
What bulb can I use instead of H11?
A 9006 bulb, also known as an HB4 bulb, is another type of halogen bulb used in automotive lighting. They're often used for low beam headlights and fog lights, similar to H11 bulbs.
Does it matter if headlight is 9005 or 9006?
The 9005 bulb is mainly used for high beams, offering brighter and more direct light. On the other hand, the 9006 bulb is primarily used for low beams, providing wider and less intense illumination.
What bulb is interchangeable with H11?
H9
How do I know if my bulb is high beam or low beam?
Tip: High beams are distinguished from low beams by their brighter light. They are sometimes referred to as “main beam” headlights. These terms are synonymous, and the term used depends entirely on the region. High beams point straight ahead, while low beams are angled down towards the road.
Are 9006 and H11 bulbs the same?
If you're in a hurry, let us save you some time - H11 and 9006 are not the same bulb, you cannot replace one with the other, and neither is better than the other, they simply have different designs and fit on different vehicles and/or different beams.
Are H11 and 9005 the same?
A: No, 9005 and H11 bulbs are not directly interchangeable. Despite their similar L-shaped designs, 9005 and H11 bulbs have different wattages and light outputs. They will not work properly in each other's sockets.
Is H11 low beam or high beam?
H11 is the low beam and 9005/HB3 is the high beam. If it's your low beam that's not working and you pulled out a HB3 bulb, you accidentally removed the high beam instead of the low beam.
Can I replace H11 bulb with LED?
All vehicles fitted with halogen headlight bulbs from the factory are suitable for LED conversion. The main advantage is a massive increase in road illumination and therefore improved safety when driving at night.
