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.

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.
