SEALIGHT 9006 Headlight Bulbs
OVERALL BEST
SEALIGHT’s reputation as a top-notch vehicle performance lighting brand precedes it, so it’s no wonder the X2 has claimed the crown. In fact, some believe the X2 to be the best SEALIGHT LED on the market.
The X2 boasts an impressive spec sheet, featuring a 20,000-lumen light output, energized by the cutting-edge 7035 LED chips. This translates to a brightness six times that of standard halogens. While it may not be the luminary behemoth on this list, it makes up for it with other standout features.
The avant-garde LED chip weaves a smooth light output and superior beam accuracy. It’s meticulously calibrated, crafting a faultless beam that suits most vehicles and driving conditions.
The lux reading might not be the brightest around, clocking in at around 1,740 lux in my tests. However, with only a 12% fade, it’s a clear winner for longer drives.
Overall, SEALIGHT has opted for consistency over raw power with the X2.
Having said that, I did notice some potential issues with the beam. In certain car housings, the cutoff appeared higher than the hotspot. This means it doesn’t quite mirror the 1:1 ratio with stock bulbs, and doesn’t always project as far as other LEDs.
For 99% of vehicles, this won’t be an issue as it still outperforms halogens with a throw much farther. However, since it’s not adjustable, you’re pretty much stuck with what you’ve got. But with a reach extending as far as 1,600 feet, you won’t be left wanting for reaction time.
I appreciated how the X2 perfectly filled in the weak spot often found at the bottom center of many bright LEDs.
The beam’s color profile is a pure, snowy white, even compared to other 6,500K LEDs. While this boils down to personal preference, it delivers unparalleled visual clarity at night. Road signs, reflectors, and lane markings are starkly defined, particularly on rural or mountainous roads.
For cooling, the X2 employs an ultra-powerful 20,000 LM silent turbo fan. Combined with a slim, 0.6-inch heat sink, it leaves plenty of space for air circulation, making the fan more effective.
From the ground up, the bulb is engineered for heat management. It’s made from aviation-grade 6063 aluminum.
This bulb’s cooling capabilities are truly impressive. It barely heated up after a 30-minute test run on high beams. It also sailed through a 30-day test at 90° F.
The X2 offers an easy plug-and-play installation. I was impressed by how snug and secure the bulb felt in its housing, thanks to its shockproof, wobble-free design. This feature, I believe, plays a significant role in preventing wear and tear.
As a CANbus-ready bulb, it caused minimal internal error codes, and I detected no interference.
Moreover, it’s IP67 rated, meaning it can withstand nearly any conditions.
All these features more than make up for the relatively high 150-watt power consumption (75 watts per bulb).
Considering all this, it’s hardly surprising that this bulb can last up to 50,000 hours, or 10 years. Reports of early burnouts or other technical defects are virtually non-existent. However, these bulbs do carry a somewhat heftier price tag, but I’d say you’re getting what you’re paying for.

Cons
- Power consumption is a bit higher than other bulbs
- Beam pattern not perfect on all vehicles
Hikari 9006 LED Headlight Bulbs
BEST BUDGET
For those of us who have an eye on our budget, Hikari’s H13 LED bulbs are an absolute blessing, and the slight dip of 15% in brightness is a small compromise to make.
The Hikaris churn out a substantial 12,000 lumens of brightness, which surpasses halogens by a whopping 330%. The beam illuminates everything within its reach as if it were a sunny day.
Each bulb is equipped with six customized LED chips, resulting in an impeccably calibrated beam. I didn’t spot a single dark area to blemish the beam pattern, nor did I have to contend with any blurriness.
This translates into a clearer line of sight for us drivers and an enhancement in road coverage.
The lux reading came in a bit lower at around 1,500 lux. This is slightly above the average and quite in line with what I’d expect from a top-notch 12,000-lumen LED.
Sporting a 6000K color profile, Hikari’s beam is a pure white. This ensures a higher beam clarity, making it a breeze to identify road obstacles or interpret signs.
The cool white appearance also constitutes a significant style upgrade from stock bulbs.
Should the beam not be quite right for your car or your preferences, you can customize it with the adjustable collar.
High-power bulbs often grapple with durability and consistency. But, the Hikari Thunder boasts a host of technology to combat that.
An intelligent IC driver is in place to regulate power consumption and ensure a smooth operation. It staves off overheating and filament degradation, even under strenuous use. This driver is equipped with a special technology that prevents bulb overload.
The bulbs also come with an integrated CANbus in the design. While it usually prevents error codes or flickering in most cars, it’s not infallible. In some instances, you may need to install external error cancellers or resistors.
Cooling is managed by a 10,000 RPM fan. Granted, it’s not as high-speed as those in other bulbs I’ve tested, but the Thunder doesn’t need such a robust fan due to its superior heat management.
This means that the fan operates much quieter than the 12,000 or 20,000 RPM ones. It also helps to keep the bulbs’ individual power consumption to a low 30 watts.
Despite running non-stop for a week, these bulbs didn’t exceed 300°F. However, they do run a bit hotter than premium LEDs, like the SEALIGHT and AUXITOs.
This enhanced efficiency and cooling also boost lifespan and durability. You can expect over 50,000 hours of illumination, which is about the best you can hope for from LEDs in this category.
The only drawback I noticed was that the beam’s light started a bit further from the car. This results in a small blind spot right in front of the car. On the flip side, you gain a much further field of vision.
Pros
- 12,000 lumens
- Longer throw and wider angle of projection
- Better road coverage
- Precise beam pattern
- Free of dark spots
- 6000K color profile
- Integrated CANbus eliminates error codes and flickering
- Dual 10,000 RPM cooling fans
- Intelligent IC driver keeps power consumption efficient
- Latest CSP chips provide anti-overload protection
- Rated to last around 50,000 hours
- Low 30-watt power consumption
- Very affordable
Cons
- Dual fans can get loud at times
- Operating temperatures can get high
AUXITO 9006 LED Headlight Bulbs
BEST PREMIUM
These 9006 LEDs might hit your wallet a bit harder than the competition, but from my perspective, it’s a cost worth bearing.
Auxito has incorporated the latest LED technology with 7035 series chips. These chips are more efficient, potent, and have a longer lifespan than their predecessors. On the performance front, you’re in for a bright 20,000 lumens, which is an absolute boon for nighttime driving.
Having twelve chips on board results in a more even and finely-calibrated beam, which is up to six times brighter than your standard halogens, ranking it high among LEDs.
One standout feature is its slim baseboard, coming in at only 0.3 inches. This design brings the chips closer to the light-emitting area of halogen bulbs, allowing a 360° beam without dark spots, in perfect 1:1 ratio.
Moreover, the beam has minimal glare, making it a safer option for other drivers on the road.
The lux reading was decent, if not extraordinary, clocking in at 1,560 lux with the projector test. The reflectors scored around 2,000 lux. But as with most Auxito bulbs, there’s a relatively high light drop-off of about 30%.
With a color temperature of 6000K, it’s almost identical to the Hikari, but leans closer to pure white than the SEALIGHT. While I personally lean towards a touch of blue in my light, this is a matter of personal preference.
Nevertheless, the beam drastically enhances the ability to differentiate between obstacles. I can’t find any faults when it comes to visibility and reflectivity.
The front of your vehicle also gets a substantial style upgrade with the cooler beam lending a more modern aesthetic. That said, I would have preferred the pure bluish-white of 6500K.
Crafted from aviation-grade aluminum, these bulbs exhibit the high build-quality we’ve come to expect from top LEDs, making them less susceptible to physical damage.
I also appreciate the all-in-one design. The integrated driver and fan save space within the housing and eliminates any unnecessary steps from the installation process. You’re looking at a one-off plug-and-play installation, with no extra wires or connectors to worry about.
Cooling primarily relies on a 12,000 RPM silent turbo fan. While I initially thought this might be underpowered for a 20,000-lumen bulb, the copper baseboard pulls its weight by conducting heat away from the sensitive components.
This efficient design also keeps power consumption at a low 50 watts per bulb.
Moreover, the claimed 50,000-hour lifespan is no marketing gimmick. It’s a direct result of efficient cooling and power consumption.
I did encounter a bit of stereo/radio interference on certain car models, but this is fairly typical for aftermarket LED bulbs. A quick fix was to install an additional decoder, like I did.
The great news is the IP67 rating. This means the Auxito’s can weather the harshest conditions with ease. The manufacturer is so confident in their product that they offer a 2-year warranty. That’s an impressive coverage period for an LED headlight.
Pros
- Latest 7035 LED chips
- 20,000 lumens brightness
- Beam stretches further down the road
- Wider field of view
- 6000K color profile
- Improved visibility
- Noticeably easier to differentiate between obstacles
