Dual headlights are generally replaced with a 9004 bulb. 

There are loads of 9004 bulbs on the industry, which indicates you finish up spoiled for decision. With so significantly range, how are you supposed to pick the correct a single? 

The excellent news is you have me to back you up. I reside, breathe, and sweat vehicles, so I know precisely what you need to appear for. 

I spent hours testing ten well-known 9004 LED headlights and located the brightest 3. 

The Auxito 9004 was the brightest set of LED headlight bulbs out of the lot. The purpose? 

Impeccable brightness and heat retention and effortless installation. 

I’ll comply with that with a spending budget alternative and a runner-up for brightest.

Let’s take a closer appear at the brightest 9004 LED headlight bulbs.

Auxito Brightest 9004 Headlight Bulb

General BRIGHTEST

Brightest of Them All

So what’s generating me gush more than the Auxito 2023 9004 LED headlight bulbs as the torchbearer for brightness? The producers claim an astounding 20,000 lumens per pair, and in my private expertise, I witnessed them peaking above three,000 lux – speak about getting super vibrant!

My Testing Methodology

The method of testing remains continual. I spot the bulbs 20 feet away from my lux meter, which enables me to measure the brightness and beam pattern.

I’m drawing a comparison right here in between the Auxito 2003 9004 LED bulbs and stock halogens. Your standard halogen bulb will churn out 725 lux in the projector test, and 910 lux in the reflector test.

During the projector test, the Auxito 2003 9004 LEDs clocked an initial score of 1,573 lux, a enormous 848 lux boost compared to halogen bulbs. 

A subsequent reading taken soon after an typical US commute time of 27 minutes, revealed that they retained a commendable 82% brightness at 1,290 lux, surpassing the typical of 77%.

The reflector test had the Auxito 2023 9004 LED bulbs kicking off with an impressive three,160 lux (a whopping two,250 lux far more than halogens). We’re speaking about a staggering 350% brightness increase – really spectacular final results.

After 27 minutes, these bulbs maintained their 82% brightness retention with a score of two,591 lux.

What struck me was the exceptional handle more than brightness and path of light, specially offered the higher lux readings. The generally problematic reduced center location was nicely illuminated, boasting a clear reduce-off.

Since the reduce-off is greater than usual, it is vital to align the lights appropriately to avoid dazzling oncoming drivers. 

While the bulbs are advertised as 50 watts each and every, I recorded 42.four watts for the duration of my test.

Color Temperature 

The AUXITO 9004 lights boast 6000 Kelvins, translating to a cool white for enhanced clarity.

My preference for LEDs stems from the reality that stock halogens usually generate a yellowish light with a colour temperature of three,000K. The white hue of the LEDs brings objects in front of my automobile into sharper concentrate, generating me really feel far more safe when I’m behind the wheel.

Managing the Heat

The Auxito 2023 9004 LED bulbs incorporate a dual cooling program, function a double-sided copper board, and are encased in an aviation-grade aluminum physique. They also come with a constructed-in 12,000 RPM higher-speed cooling fan.

Disappointingly, none of these functions appear to be efficient in heat management. My temperature tests revealed a staggering 219°F for the primary unit and 154°F for the driver soon after 27 minutes.

These temperatures are excessively higher, and I’m skeptical about the bulbs’ potential to final the advertised 50,000 hours.

Noteworthy Features 

The 9004 LED headlight bulbs come with a 360-degree adjustable collar. I appreciated the thoughtful gesture from Auxito to give antistatic gloves to shield my hands for the duration of installation.

Auxito deploys intelligent CSP chips affixed to an ultra-thin .039 inch baseboard to maximize brightness and boost nighttime visibility. This was substantiated in my test final results.

Installation

The simple but compact design and style is ideal for installation. It took me significantly less than ten minutes, courtesy of the 1:1 halogen plug-and-play design and style. Aligning the beam was just as easy.

Durability and Longevity

The AUXITO 9004 comes with an IP67 rating for waterproofing. I braved a heavy storm for almost an hour and the bulbs stood their ground, displaying no indicators of difficulty.

Auxito promises a lifespan of 50,000 hours, but contemplating the higher temperatures, I doubt they’ll hit that mark. However, they need to provide a strong overall performance for at least the duration of the two-year warranty.

Feedback from Other Drivers

The AUXITO 9004 LED headlight bulbs have garnered more than two,000 consumer evaluations with an typical rating of four.four/five stars. 

Users have applauded the bulbs for their effortless installation and enhanced brightness for the duration of nighttime drives. 

The principal downside noted by customers is the bulbs’ tendency to overheat, which is one thing I seasoned as nicely.

The Final Verdict

The Auxito 2023 9004 LED headlight bulbs earn my vote as the brightest bulbs with a 350% brightness improvement more than halogens, it is difficult to locate something that can hold a candle to these.

Top Pick for the Budget Conscious

Just due to the fact you are mindful of your spending budget does not imply you have to settle for significantly less, and the Fahren Forscher 9004 LED headlight bulbs are a testament to that. The producers have pegged them at 14,000 lumens per pair, and they hit as higher as two,390 lux, promising enhanced brightness. The only point that is spending budget-friendly about them is their price tag tag.

My Trial Run

In my projector test, these bulbs clocked in at an initial 1,472 lux, which is roughly double what you’d get from stock halogen bulbs. After the usual 27-minute test period, they retained a whopping 89% brightness, delivering 1,313 lux. This outcome was nicely above typical, showcasing outstanding heat retention.

During the reflector test, the Fahren Forscher 9004 LEDs registered an initial two,390 lux, a substantial 1,480 lux jump more than stock halogen bulbs, equating to about 250% further brightness. After the 27 minutes, they held steady, preserving the 89% brightness level at two,137 lux.

The tests also revealed a decent reduce-off point in line with common headlight expectations. There was superb command more than the brightness, with only the usual suspects – the best and bottom center – getting slightly weak spots.

I was fairly impressed with the excellent light handle and a nicely-balanced distribution in between the left and correct sides. The clean reduce-off also ensured that there was barely any scattering of light.

Interestingly, soon after 27 minutes, my tests showed that the bulbs hit 25.9 watts, a fair bit brief of the advertised 35 watts. 

Color Temperature 

These headlight bulbs sport a cool white colour at 6500 Kelvins. When I took them for a spin, I was pleasantly shocked by the stark clarity of road indicators in comparison to the usual halogens.

Keeping the Heat in Check

These bulbs are constructed from aviation-grade aluminum and function a exclusive hollow-carved heatsink design and style. They also boast a constructed-in 12,000 RPM turbofan. My tests showed that the primary unit reached temperatures of 185°F, although the driver warmed up to 120°F.

While these temperatures are not as higher as the Auxito 2023 9004s, they’re nevertheless a tad hotter than I’d choose. This tends to make me query the claimed longevity of 50,000 hours.

There’s an additional quirk about the fan: it gets seriously loud. While this might not be an concern for some, I located it increasingly noticeable and mildly distracting more than time.

Handy Extras 

I located it neat how all Fahren bulbs come packaged in a tiny black bag. It felt like unboxing a surprise present. Inside, you will locate a detailed manual, which honestly, wasn’t necessary as the bulbs had been a breeze to set up. In addition, there’s double-sided tape, a tiny aluminum wrench for the adjustable collar, and 4 zip ties.

What sets Fahren apart is the inclusion of two further gaskets – a thoughtful touch.

Installation

Thanks to the plug-and-play design and style, I breezed via the installation method, wrapping it up in about 5 minutes. Adjusting the beam was a similarly swift affair.

Durability and Longevity

The Fahren Forscher 9004 LED headlight bulbs come with an IP68 rating, signifying their waterproof, dustproof, and usually climate-resistant traits. This is the very best achievable rating, and it absolutely bolstered my self-confidence for the duration of my drives in the rain.

They claim a lifespan of 50,000 hours and Fahren provides a 1-year warranty.

Feedback from Fellow Drivers

The Fahren Forscher LED headlight bulbs have raked in more than 59,000 consumer evaluations, boasting an typical rating of four.five/five stars.

Users have heaped praises on the ease of installation and the efficacy of the lights.

The noisy fan has been a typical point of complaint amongst drivers, so it appears I’m not the only a single irked by it.

In Conclusion

With their cost-effective price tag and exceptional overall performance, these lights surely make for an desirable alternative. They rank very amongst the brightest 9004 bulbs for spending budget-conscious drivers. With these installed, you can anticipate clear visibility and far more confident driving soon after dark.

Strong Second Option

The Novsight 9004 LED headlight bulbs are undoubtedly a robust second spot contender. Boasting more than two,000 lux, they exhibit brilliant light retention and are marketed at 13,000 lumens per pair. To best it all off, they come with some handy freebies.

My Testing Journey

In my projector test, the Novsight 9004 LEDs came in with an initial rating of 1,320 lux, a excellent 595 lux above the common halogen bulbs.

After 27 minutes, they slipped to 77% brightness, which is about par for the course.

As for my reflector test, it revealed an initial rating of two,340 lux, a hefty 1,430 lux far more than stock halogens, generating them a strong 250% brighter than common bulbs.

After the usual 27-minute period, they held on to 77% brightness, translating to 1,801 lux.

The test also showed a decent reduce-off point, even on the best and bottom, which is fairly a uncommon locate. The standard weak spot was nicely addressed, major to minimal scattering and amazing all round light handle.

The bulbs are advertised at 60 watts per set, but my readings showed each and every bulb clocked in at 25.1 watts.

Color Temperature 

The bulbs give off a pleasant and sharp cool white light, measured at six,500 Kelvins. I truly enjoyed hitting the road with these bulbs installed I could discern objects on the road quicker and far more clearly than with the factory bulbs.

Handling the Heat

I’m generally skeptical about all-in-a single units due to their tendency to heat up rather speedily. The Novsight 9004 LED bulbs, even so, are a pleasant exception. The integrated silent turbofan and the aviation aluminum material appear to do a stellar job at heat management.

My tests showed that the unit reached a comparatively cool 121°F soon after 27 minutes. And correct to the claim, the fan was certainly silent, as opposed to the Fahren Forschers.

Handy Extras 

One of the standout elements of these bulbs is their exclusive all-in-a single design and style, with an integrated driver and an completely metal building – no plastic components to be noticed. This tends to make for a strong and sturdy bulb, created even far more attractive with a satin finish.

To sweeten the deal, the Novsight 9004 LED headlights come with gifts, like a textile keychain and a Novsight-branded nano traceless magic sticker – nifty tiny additions.

Installation

Installation was a breeze, thanks to the 1:1 halogen plug-and-play design and style, a perk of the all-in-a single structure. It took me significantly less than ten minutes to get it carried out. Aiming the beam was equally effortless, and I very advocate undertaking this to steer clear of blinding other drivers.

Durability and Longevity

These headlight bulbs boast an IP68 rating, which implies they’re weatherproof and dust-resistant. They’re touted to have a staggering estimated lifespan of one hundred,000 hours, which considerably outstrips the typical. However, I stay sceptical about this claim.

Feedback from the Road

The Novsight 9004 LED headlight bulbs presently hold a four.six/five star rating.

Drivers have specifically lauded the compact and robust construct of these headlight bulbs, as nicely as the impressive brightness they supply.

The primary complaints seem to center about their unsuitability for DRL use.

Final Thoughts

The Novsight 9004 LED bulbs clinch the runner-up spot in my book. They might not fairly match up to the brightness of the Auxito 2023 9004s or their superior heat retention, but they’re far more cost-effective and handle to keep impressively cool.

Important Considerations When Buying 9004 LED Headlight Bulbs

9004 bulbs are not for every single automobile. I know for a reality that they’re well-known replacements for most VW automobiles and some Toyotas. It’s essential to verify the vehicle’s user manual to decide if they’re appropriate for other folks.

The other point to maintain in thoughts about 9004 bulbs is that they’re dual-beam, so they only match in automobiles with two headlights. If the automobile has 4 headlights, it requirements a various bulb for higher and low beams, so the 9004 is not appropriate.

Some drivers try to swap the 9004 for the 9007, which can be carried out if the socket is appropriate. The distinction in between the two is that the 9004 has a ground pin on a single side and the higher/low pins in the middle, although the 9007 has its ground pin in the middle and higher/low optimistic pins on the outdoors.
