Understanding the 9004 Bulb Type
What is a 9004 bulb?
The 9004 bulb is a popular type of halogen headlight bulb found in older vehicles. With dual filaments, it can operate as both high and low beams.
Is 9004 bulb high beam or low beam?
Thanks to its dual filaments, the 9004 bulb works for both high and low beams. It can switch between the two to meet your needs.
Brightness and Lifespan of 9004 bulb
A basic 9004 bulb produces around 700 lumens on low beam and 1200 lumens on high beam with 45 to 65 watts of power. It has a yellow-white light at 3200K color temperature.
In terms of the lifespan, a standard halogen 9004 bulb lasts around 320 hours.
Compatibility of 9004 bulbs
The 9004 bulb is compatible with headlights in many 1980s and 1990s vehicle models, including those from Audi, Chevrolet, Dodge, Ford, Hyundai, Mazda, Mercedes-Benz, Toyota, Volkswagen, and others.
* Before buying replacement bulbs for your vehicle, always double check your owner's manual to confirm you're getting the right type. For helpful details on finding the correct headlight bulb for your specific vehicle, refer to this guide.
Comparing 9004 with Other Bulb Types
Is 9004 the same as HB1?
Yes. The HB1 bulb provides the exact same function as the 9004 bulb; the names are simply interchangeable for the same automotive part.
Is 9004 the same as H4?
While the 9004 and H4 (or 9003) bulbs are both dual-filament, their filament configurations differ. The 9004 has filaments placed horizontally, whereas the H4's filaments are oriented vertically. As a result, they generate distinct beam patterns and are not interchangeable.
What is the difference between 9004 and 9005?
The 9005 bulb only has a single filament and is meant solely for high beams. While the dual-filament 9004 can serve as both high and low beams, the 9005 can only be used for high beams.

What is the difference between 9004 and 9007 bulbs?
The 9007 bulb is also a dual-filament type, but its filament positioning differs from the 9004.
The 9007 bulb features vertically-oriented filaments, whereas the 9004 bulb has filaments positioned horizontally. Therefore, you cannot use 9007 instead of 9004.

FAQs about 9004 Bulbs
Q1: Are 9004 bulbs the same as H4 bulbs?
No, 9004 and H4 bulbs are not the same. While both are dual-beam bulbs designed to provide high and low beam functions, they differ in their electrical specifications, wiring configuration, and performance output. Although they may look similar and use comparable connectors, they are not interchangeable due to these differences.
Q2: What’s the difference between 9004 and 9007 bulbs?
The main differences lie in their design and wiring. A 9004 bulb uses a dual-filament setup with separate filaments for high and low beams, while a 9007 bulb operates differently in terms of electrical control and beam switching. Additionally, the pin configuration and wiring layout are not the same, which means they cannot be swapped directly.
Q3: What vehicles use 9004 bulbs?
9004 bulbs are commonly found in a variety of vehicles, including sedans, SUVs, trucks, and even some motorcycles. They are typically used in older headlight systems that require a dual-beam bulb for both high and low beam functionality.
Q4: Is there an equivalent bulb to 9004?
The 9004 bulb is also known as an HB1 bulb. While H4 (also referred to as 9003) is another dual-beam option with a similar design, the two are not directly compatible due to differences in wiring and electrical characteristics. Care should be taken when selecting replacements to ensure proper fitment.
Q5: How many lumens does a 9004 bulb produce?
The brightness of a 9004 bulb depends on the type and manufacturer. Standard halogen versions typically produce around 700 to 1,200 lumens. However, modern LED upgrades can deliver significantly higher output, offering improved visibility and performance.
