9004 vs 9007 bulbs: Key Differences, Compatibility & Swaps

Are 9004 and 9007 bulbs the same? Please make no mistake, they are very different.

You may think that 9004 and 9007 bulbs look almost identical, but in fact, they have obvious differences in internal structure, so they cannot be used interchangeably. Choosing the wrong bulb will not only make it impossible to install, but it may also affect driving safety. Don't worry, this article will help you quickly understand the difference between the two and help you choose the right bulb, saving time and worry.

9004 and 9007 Headlight Bulbs

9004 Bulbs

9004 bulbs (also called HB1) are dual-filament halogen bulbs, which means they can provide both low beam and high beam. And 9004 headlight bulbs are commonly used in many car models, with stable brightness, suitable for driving in various road conditions.

9007 Bulbs

9007 bulbs are also dual-filament designs, which can also take into account the functions of low beam and high beam. They are used on many American cars and some Japanese cars. Compared with 9004, 9007 has stronger performance and is a good choice for driving at night or in bad weather.

Main differences between 9004 vs 9007 headlight bulbs

Filament structure

From the appearance, 9004 and 9007 bulbs are indeed very similar, but their filament layouts are completely different:

9004: Filaments are arranged horizontally

9007: filaments are arranged axially (that is, front and back direction)

This is not a small detail. The direction of the filament will directly affect the projection effect and focus of the light. If you install a 9007 bulb into a lamp originally designed for 9004, the light beam will run around, so not only can it not illuminate the road clearly, but it is also easy to scare the oncoming driver, which is very dangerous.

Base

The base of 9004 is P29t, and 9007 uses PX29t.

Although the two sound only one number different, they have different structures and different sockets, and cannot be directly replaced.

Compatibility

9004 bulbs can be cross-referenced with HB1, and 9007 bulbs can be used interchangeably with HB5.

This is also an important difference between 9004 and 9007. Although they have their own equivalent models, they are not interchangeable with each other. Before changing the bulb, it is recommended to check the vehicle manual or the original part number to avoid buying the wrong one.

Parameter comparison of 9007 vs 9004 bulbs

Application

We have introduced 9004 and 9007 bulbs before. They are both dual-filament structure designs, so 9004 and 9007 bulbs can be used as low beams and high beams at the same time.

Power

There are differences between 9004 vs 9007 bulbs in terms of power. The power of 9004 bulbs is 45 watts in low beam mode and 55 watts in high beam mode. The power of 9007 headlights is 55 watts in low beam mode and 65 watts in high beam mode.

Therefore, the power of a 9007 is generally higher than that of a 9004 headlight bulb.

Brightness

The lumens of the bulb are decided to a certain degree by the bulb power, so the 9004 and 9007 brightness will also be different. Headlight bulb 9004 typically has 700 lumens of brightness in low beam and 1000 lumens of brightness in high beam. Bulb 9007 typically has 1000 lumens brightness in low beam and 1600 lumens brightness in high beam.

Lifespan

Both halogen bulbs, 9004 and 9007, share the same lifetime since the 9004 headlight has a lifespan of 600 hours, and the 9007 bulb has a lifespan of 800 hours.

In general, there is a big distinction between headlight bulbs 9004 vs 9007, and we believe that from this post, we can help you make a good decision. If you are tired of using dim halogen bulbs and want to change them, LED bulbs will be your best choice.

Upgrading bulbs to LED

If you're fed up with the dull and dim halogen bulbs, LED is the way to go.

 Brighter: LEDs are a few times brighter than conventional halogens, which results in safer night driving.

l Wider field of view: 9004 and 9007 LED light bulbs will illuminate further and wider, and you don't need to worry about blind spots.

l Super long life: LED bulbs can be used for tens of thousands of hours, nearly 100 times longer than that of halogen lamps! That is, there is no need to constantly change the bulbs.

Many car owners choose RIMTHIN brand 9004 or 9007 LED bulbs. As a brand focusing on high-performance LED lighting, RIMTHIN has outstanding performance in brightness, installation convenience, and service life, and has helped countless drivers say goodbye to blurred vision.

Warm reminder: Before changing the lights, remember to check your owner's manual to ensure that you buy the matching model to avoid installation problems or electrical problems.

9004 vs 9007 Comparison Summary

Selecting the right headlight bulb for your vehicle is a critical component of nighttime driving safety. Knowing the main differences between 9004 and 9007 bulbs allows you to make the right decision. Correctly matching bulbs not only provides clearer lighting effects, but also significantly improves driving comfort and safety. Before you buy, make sure that you pay attention to brightness, quality, and compatibility with the car to ensure that you buy a lighting solution that gives you performance and safety.
